http://en.wikipedia.org/wiki/Deccan_Traps\n\nThis page has some information about the Deccan Traps. I will copy some of it here:\n\nDeccan Traps\nFrom Wikipedia, the free encyclopedia\nJump to: navigation, search\n\nThe Deccan Traps is a large igneous province located in west-central India and is one of the largest volcanic features on Earth. It consists of multiple layers of solidified flood basalt that together are more than 2,000 m thick and cover an area of 500,000 km². The name is derived from the Swedish word for steps which refer to the step like hills forming the landscape of the region.\n\nThe Deccan Traps formed between 60 and 68 million years ago,[1][2] at the end of the Cretaceous period. The gases released in the process may have played a role in the extinction of the dinosaurs. Before it was reduced to its current size by erosion and continental drift, it is estimated that the original area covered by the lava flows was as large as 1.5 million km². The volume of basalt is estimated to have been 512,000 km³.\n\nIt is postulated that the Deccan Traps eruption is associated with a deep mantle plume or hotspot. The plume or hotspot, known as the Réunion hotspot, is suspected of causing both the Deccan Traps eruption and opening the rift that once separated the Seychelles plateau from India. Seafloor spreading at the boundary between the Indian and African Plates subsequently pushed India north over the hotspot, which now lies under Réunion island in the Indian Ocean, southwest of India. The mantle plume model has, however, been challenged.[1]\n\nA large impact crater has been recently reported in the sea floor off the west coast of India. Called the Shiva crater, it has also been dated at 65 million years, right at the Cretaceous-Tertiary (K/T) boundary. The researchers suggest that the impact may have been the triggering event for the Deccan Traps as well as contributing to the acceleration of the Indian plate in the early Tertiary.[3] However, opinion in the geologic community is not unanimous that this feature is actually an impact crater.[4] Also, the reported age is in the middle of the ages given for the Deccan rocks.\n\nThe planet Venus is also thought to undergo vast basaltic flood eruptions, but on an even greater scale than those at Deccan Traps. It is not known whether the mechanisms are similar; Venus appears to lack Earth's plate tectonics and its internal structure may differ in other ways as well.\n\nThe "red bole" you mention could be the Reunion hotspot. Look at this link:\n\nhttp://en.wikipedia.org/wiki/R%C3%A9union_hotspot\n\nRéunion hotspot\nFrom Wikipedia, the free encyclopedia\nJump to: navigation, search\n\nThe Réunion hotspot is a volcanic hotspot which presently lies under the Island of Réunion in the Indian Ocean. The hot spot is believed to have been active for over 65 million years. A huge eruption of this hot spot 65 million years ago (MYA) is thought to have laid down the Deccan Traps, a vast bed of basalt lava that covers part of central India, and opened a rift which separated India from the Seychelles plateau. The Deccan Traps eruption coincided with the extinction of the dinosaurs, and there is considerable speculation that the two events were related. As the Indian plate drifted north, the hot spot continued to punch through the plate, creating a string of volcanic islands and undersea plateaus. The Laccadive Islands, the Maldives, and the Chagos Archipelago are atolls resting on former volcanoes created 60-45 MYA that subsequently submerged below sea level. About 45 MYA the mid-ocean rift crossed over the hot spot, and the hot spot passed under the African Plate.\n\nThe hotspot appears to have been relatively quiet from 45-10 MYA, when activity resumed, creating the Mascarene Islands, which include Mauritius, Réunion, and Rodrigues. Mauritius and Rodrigues ridge were created 8-10 MYA, and Rodrigues and Réunion islands in the last two million years. Piton de

I am afraid to say you won't get any relevent information about it on Yahoo Answers. Search out the Google for it, especially search under pages from India.

Red mercury is a semi-mythical substance that was claimed to be used in the creation of nuclear bombs (some believed that red mercury was a ballotechnic material). It has risen to prominence due to "sting" operations against putative terrorists. These consist of offering them "red mercury" and then arresting them when they make arrangements to buy this ficticious substance.\n\nhttp://chemistry.about.com/cs/chemicalweapons/f/blredmercury.htm

Mariguana is a rare semi-metallic halide mined under the hills of The Netherlands, Mexico, British Columbia, Turkey, Iran and Virginia, primarily by Thracian slaves captured during the Gulf War. Before the 1850s, this ore was known to the ancient Greeks who found it in the rubble of Agean volcanos, as "Fire of Kronos", or "Kronic", due to its luminescent qualities, and the strange way time seemed to slow down when humans were exposed to it. Greek Soldiers believed that The Fire of Kronos was a good luck charm that increased appetite, prevented nausea, and enhanced appreciation of music and sex, and hoplites were known to carry rocks of the ore with them in baggies full of local weeds.

Depends on what criteria you set, but the Deccan Traps in India 60- to 65Ma ago was very large. It was classed as a supervolcano much like the one in Yellowstone park at the moment. \nAlthough some people claim that the formation of Yellowstones caldera around 2 million years ago was the largest volcanic eruption ever.

A short distance off the coast of the remote Micronesian island of Pohnpei lies one of the greatest archeological mysteries in the world, the Lost City of Nan Madol. Built on an ancient coral reef and covering more than 11 square miles, this ancient city is made up of hundreds of artificial islets, intersected by numerous manmade canals. Even more curious, many of the city’s larger islands are connected by submerged tunnels. First discovered in the early 1800’s by European sailors, this baffling and immense megalithic stone city may contain evidence for the fabled lost continent of Mu.\n\nThe mysterious Nan Madol is built entirely out of gigantic magnetized basalt crystals, some weighing as much as fifty tons. In fact, the entire city contains an estimated 250 million tons of the prismatic basalt rock.

Yes. It is a bit of a worry as its is displaying signs of 'grumbling'. If you are interested, there has been a volcanic eruption before which is potentially the size if Yellowstone blows it top. It happened 60-65Ma ago and is one of the possible reasons the Dinasaurs died out. \n\nIf and when Yellowstone goes, there is a very good chance that pretty much most of the US is going to be destroyed by either the flowing lava or the gases released into the atmosphere.\n\nAnyway I have provided you a link to the above mentioned Deccan Traps.

There are mainly 2 broad classes of magma, rhyolitic and basaltic. Due to the chemical characters(more mg and fe) of the basaltic magma, it is denser but less viscous than the acidic (rhyolic) magma.  The rhyoltic lava due to its excess silica content are highly viscous and due to this reason after eruption from the plate collision site(normally we find volcanic eruption where an ocenic plate subducts beneath a continental plate though there are another kind of volcanic site called hotspot volcano which can be anywhere regardless of the plate position)it mounts up significantly but the basaltic lave flows downslope and  cannot mount up ( eg Deccan Trap in India and the whole ocean crust).  So we find the volcanoes are mainly made up of rhyolitic lava.

No record of who actually discovered it. It is several thousands of years old. It can be naturally extracted from Willow bark.

Linga (or Lingam) is used as a symbol for the worship of the Hindu God Shiva. While its origins are debated, the use of this symbol as an object of worship is a timeless tradition in India; mainstream scholars connect the origin of the lingam to the early Indus Valley civilisation. Lingam is usually found with Yoni, the pedestal. As such, Lingam represented the male entity of the universe, while Yoni represented the female; it was natural togetherness of the male (Shiva) and female (Shakti) (Lingam and Yoni) as the point of energy, point of creation, and point of enlightenment. Such revelation was later enriched by many philosophies and theologies as man's knowledge of God widened with civilization.

It's called the "Moho," which is short for "Mohorovicic Discontinuity."  It is named for the scientist who postulated its existence.  No one has ever drilled down far enough to see it, but that layer has certain unique physical properties.

that'll be chalcedony. it differs from quatrz in it's shape, as it usually occurs in botryoidal masses, whereas quartz occurs more in hexagonal prisms. chalcedony is similar to opal, but can be distinguished by its higher specific gravity. it can be formed as a dehydration product of opal, hence the connection. the colour is highly variable, as it can be white, blue, red, green, brown or black, and varieties of chalcedony include jasper, agate, chrysoprase, onyx and carnelian. it's formed in rock cavities, especially lavas, and it develops at relatively low temperatures, whereas quartz occurs in any rock type, and usually formed at higher temperatures

The 'nagmani' or 'snake's gem' is a myth prevalent in rural India - that when a pebble or stone accidentally gets into a king cobra's mouth and pierces its way into one of its poison glands, the snake's poison forms a thick layer around the stone and solidifies as a protective coat to prevent the stone from further damaging the snake's mouth. [The myth must have been based on how a pearl is formed within an oyster !]\nThis 'stone' was rated as having a rare gem-like quality - with allegedly miraculous healing powers. It was also supposed to bring good luck to those who owned, or wore them !\n...Several Indian folk tales, from various regions, relate how brave young men [usually princes] went in search of the snake-gems - and returned with a beautiful princess as well, for a 'bonus'. \n...But no such 'gems' are formed in reality - though even now there are con-men [and women !] who sell such fakes to simpletons, who are still willing to believe in these tall tales !

Here's what I found: \n\nAborigines believe they have lived in Australia since the beginning of all creation. This culture has produced many myths and legends about opals over this span of time and the Aborigines believe the opal has a spiritual value. They believe the opal represents something an ancestor left behind as a sign of his or her presence. The Wangkumara people have a legend which tells how their people gained fire from opal stones, with the assistance of a Muda - a Creator who switches from human form to pelican. \n\nThis story is preserved in a book of Aboriginal legends, titled 'The Opal that Turned into Fire', compiled by Janet Mathews and published by Magabala Books. This legend recounts how the Wangkumara people decided to send a pelican (Muda) to explore the Northern Territory, so he could return and tell them what was there. The pelican set off with all the fish and water he would need for the journey stored in the pouch beneath his beak. After flying a while the pelican felt ill and landed on top of a hill that the Wangkumara later named Bildimini. While resting the pelican observed the ground beneath him and was amazed by its magnificent array of colors.\n\nAlthough he did not know it, what he saw was opal. The pelican was so curious he began to peck at the colored stones with his beak. Suddenly, a spark flew out and lit the dry grass nearby. The flames rose and spread slowly across the plains approaching a group of Wangkumara who were camping near Cooper's Creek. The people were able to use the fire to cook their meat and fish for the first time, and were grateful for this new gift. \n\nAnother legend tells how an earlier Muda, also in pelican form, created Cooper's Creek for the Wangkumara and filled it with fish. Wounded by a spear, this Muda died on the hill that would be called Bildimini. His blood and the water in his pouch flowed down the hillside, soaking into the earth and hardening into opal and gold.\n\n(From: http://www.bernardine.com/birthstone/opal.htm)\n\nThe ancient Greeks believed the opal gave the wearer protection from disease and was a sought after gem for its gift of prophecy and foresight. Greek astrologers, mediums and soothsayers also used the stone for divination. As well as its mystical significance and psychic vision properties, opal was also thought to aid in digestion, stomach disorder, and to cure all disease associated with the eyes. It was believed that when a person was to suffer a minor illness, the stone became dull and grey it would turn a sickly yellow when an injury or accident was about to occur. \n\nSuperstitions associated with opal continued throughout the Middle Ages, when opal was widely believed to be beneficial to eyesight, while others thought wearing opal would render the wearer invisible to the eye. It was for this reason thieves held opal in such high regard, using it as their symbol, due to this superstition. Blond haired women wore necklaces of opal to protect their hair from loosing its colour, while opal amulets were worn to attract happiness, love, good fortune and favour.\n\n(From: http://searchwarp.com/swa8911.htm)\n\nMark Antony loved opal. Indeed, it is said that he so coveted an opal owned by Roman Senator Nonius that Mark Antony banished the Senator after he refused to sell the almond sized stone, reputed to be worth 2,000,000 sesterces. (US $80,000) Mark Antony is said to have coveted the opal for his lover, Cleopatra. Legend states that one Roman Emperor offered to trade one-third of his vast kingdom for a single Opal. \n\nThat and a lot more really cool facts and lore can be found here: http://www.opalsdownunder.com.au/articles/history.htm\n\nI hope this is helpful :)
