There are some famous places where Precambrian rock is exposed such as the Canadian Shield. It spans across Canada & parts of Greenland.\n\nThe basement rock in the Grand Canyon (rock on the bottom) is also visible.\n\nMost Precambrian rock is covered w/ sediment & or sedimentary rock where lowlying areas of it exist.\n\nAnywhere where Precambrian rock has been uplifted is a good place to look. Like the Teton Mtn. Range in Wyoming. That would be your best bet. At the feet of fault block mtn. ranges.

http://www.knowledge.co.uk/sis/ba9712bp.htm\n\nCheck out the link above. What I have come to believe like many others from studying the subject of bronze age natural disastors is that often stories and myths tie very well with geological events, such as tsunamis (parting of the sea for moeses and the jews) earthquakes etc. Stories in the bible can be traced back to earlier myths which existed before the bible was written. I would not beleive hat the bible describes word for word as throught he ages, stories have been altered to provide an exaggerated picture of true events to capture the imagination of the reader/pupil. How many times have you exaggerated a story just so it sounds better to the listner? Now apply 2000years to that and you know what I mean. Anyway the above link is an interesting read.

Possibly at some time in its history. Read the linked article.

Sure, why not.  I have a map that tells elevation and is color-coded for the geologic age of the exposed rocks.  That's four dimensions.

It is a myth....a bedtime story.  The Earth was formed over millions of years.

It would really help if you knew where he had found it, fossil assemblages vary from country to country, and even locally. If you know where it is from try contacting the local museum or geology department of the university in that area.

I quote D.J. (Dave) Sauchyn: "geomorphologists have widely accepted the concept of equifinality ("same final result") or convergence, that a given landform can have different origins" from \nhttp://uregina.ca/~sauchyn/geog423/morph.html

The lower Ordovician, about 490 million years ago. This link you have to scroll down quite a bit.

Try the www.usgs.gov, it is the US geological survery website they have all kinds of information on things like that.  If the info you want isn't there there will probably be a link that you can find for that information.

Around 600,000 years old. Maybe even older.

Identification of a sedimentary facies (or any rock facies, for that matter) requires an intimate knowledge of the type locality of that particular facies, what major minerals constitute the lithogenics, and what the depositional/erosional/tectonic activity of the region was like since the formation of the facies.  \n\nFor example, when I was out west I was able to trace the Navajo sandstone throughout the four corners region, from the Grand Canyon all the way up through Utah.  There were points where the Navajo was the thickest facies, while in other regions the Navajo was very thin and nearly unnoticeable.  In those thin regions, the deposition of the Navajo might not have been as pronounced (sedimentary facies are formed by deposition of sediment), or the facies could have been exposed at the surface much longer than in other regions and subsequently eroded away.  You can determine if this happened by looking for unconformities between the Navajo and the facies above it.  \n\nHowever, there are certain characteristics of the Navajo (Aeolian remnants, highly silicic, slight oxidation) that make it the Navajo formation.  Despite the varying thickness of the facies, you can trace these rock characteristics throughout the American Southwest.  So yes, if a geologist wishes to determine the full extent of a lithogenic facies, they must attempt to trace that facies as far out as they possibly can, which means a lot of survey work.\n\nWhat most geologists do nowadays is check the state geological maps of the regions they're interested in and look for rock facies that match the facies of the rock they're studying.  Oftentimes facies that are the same facies are given 2 different names in different state geological maps.  If this occurs, the type locality of the rock is determined (IE, the best-represented sample of that rock), and the facies name is given based on the state the type locality is in.

"My short answer for the questions that need a lot of spaces for arguments. \n\n1) Good geological conditions that need oil accumulation. \n2) Good source rock preservation due to geographic and rich orgainism thriving conditions. Both fine once in the present Middle East during many million years ago. \n\nSome details are as follows \n\nIn order to reach to a satisfying answer of your question, it is important to appreciate the science of Plate Tectonics. \n\nIn geologic terms,a plate is a large, rigid slab of solid rock. The word tectonics comes from the Greek root "to build." Putting these two words together, we get the term plate tectonics, which refers to how the Earth's surface is built of plates. \n\nThese blocks or plates have different properties and behave differently in response to its gliding surface and at the time of dynamic movements. The Earth what we observe now believed to be not the same throughout the geological time. It had changed its shapes and continents and had been mobilized geographically as well. Many scientific explanations have been presented to prove the theory. Presence of fossils of similar kind of plants and animals in diversified continents, thousands of miles apart, once fused, showed the evidence of plate movements. \n\nVarious continents of the Earth floated around the globe in the geologic past, such as, Africa and South America, India and Europe and Asia. Geological past could be as ancient as 2500 million years old to few thousand years ago. It implies that a continent at the equator now, must had been near the poles once in the past, may be several millions years before the past. Every climatic zones have their internal biologic and climatic activity. \n\nWhile studying Petroleum accumulation or deposits of hydrocarbon, keep in mind, the most important factors controlling the oil accumulation are, source rock, reservoir and trap. \n\nSource rock is closely and directly related to the biological activity of the given zone which will help to concentrate the organic matter at one place and afterward it becomes preserved if met appropriate conditions. Most of the areas now comprised of Arabian Peninsula including North Africa, Saudi Arabia, Iran and Iraq, were remained near the tropical areas between latitude 20 degree south to 20 degree north during Jurassic (135 million years) late Tertiary (10 million years). Biologic activity and productivity is the highest in these tropical and equatorial zones compare to the area lying near the poles. The rocks of the Jurassic and Cretaceous have been found good source and reservoir rocks throughout the Saudi Arabai, Yemen, Sudan Iraq and Iran. On the other hand reservoir rock particularly in the Paleozoic age are either deposited in the continental environments which have less prominent cement between the grains. Such rock are very porous and capable to store huge volume of oil and gas. Middle Eastern areas remained tectonically less active or passive and consequently much less breaking and destruction activity prevailed in that part of the Earth. \n\nIn summary, middle east has been encountered all the favourable conditions for the generation, preservation and accumulation of hydrocarbon during the geological history of the area. India has oil and gas because it has vast sedimentary basins in the west and east of the continent, both in offshore and land" (Syed Tariq Hasany).

sell it on ebay if you find someone to purchase something like that with no certificate of authenticity from a geologist to support your assertions.

This is something I do routinely almost every day as a petroleum geologist. We are constantly re-examining old data and combining it with new information in our search for new undiscovered and possibly bypassed oil reservoirs. A significant part of the future oil reserves in the US is going to come from this type of detective work. Some major discoveries have resulted from geologists going back and re-examining old well logs. \n\nYou have to keep in mind that the information coming from a well represents only one point on a map. Combining the information from that point with well data from a recently drilled well or new 3D siesmic data might change the entire interpretation of a specific formation. I saw a great example recently where a geologist realized that an unconformity extended across a region where no one else had noticed it before, and was able to find stratigraphic traps in areas that were near existing dry holes, but the wells had missed the reservoir.
