What is the the depositional environment of the Cretaceous Wealden sedimentation?
337872
I did a search in Google Scholar and came up with some articles to start with.  I posted the URL of the search results below, hopefully that will work, otherwise, go to http://scholar.google.com/ and search using "environment of the Cretaceous Wealden sedementation.  If you have access to a nearby library they may have the publications that contain the articles, or, you could ask them about there interlibrary loan department.\n\nI suggest starting with these articles and looking at the article references to find some relevant books and/or more articles.  Good Luck!

No, not likely. \n\nCoal is formed from (coalified) plant material. Petroleum and natural gas are formed from organic remains of plants, primarily microscopic phytoplankton, and small marine animals called zooplankton. \n\nIn the rare instance that a dinosaur's dead body might have been carried by water into an oxygen poor (anaerobic) environment and quickly buried by catastrophic deposition of shales, there might have been some protein or lipids from that carcass that eventually converted to oil, but it is far more likely that the body of a large organism like a dinosaur would become food for decomposing bacteria and other scavengers long before it had the opportunity to be converted to oil by the process of heat and pressure known as catagenesis.\n\nThere is no truth to the answer that the "traditional theory is that petroleum formed during the same period as dinosaurs" as most of the world's petroleum reservoirs are known to be younger than that, and many are known to be older. One deposit of oil has been found that is only about 4,000 years old. \n\nDr. Thomas Gold's hypothesis of abiotic oil has never been substantiated by any evidence of oil that is NOT from biological sources.  Very few geologists agree with Gold, and none have been able to prove he was correct. There is considerable evidence in the form of molecular structure, isotopic fractionation, and more that proves that little if any oil is from the abiotic mechanism Gold hypothesized. The big problem with Gold's hypothesis is that oil and gas ARE NOT found in igneous rocks, as one answer here suggests.\n\nI'm a petroleum geologist.

Check out this site: http://www.expanding-earth.org/\nSome scientists may dispute the notion that additional solid matter is created from solar energy by photosynthesis in plants and other living organisms, but they should consider coal beds that were formed from trees in the Carboniferous (~360 to ~290 Ma) but are now buried under deep overburden that accreted later. The huge fossilized tree trunks found in the Petrified National Forest near Holbrook in eastern Arizona are additional evidence of mass from solar energy. Also consider the massive deposits of limestone created by marine fauna (fish, coral, bivalves, microfossils, etc.) in earlier epochs and this growth continues today. Today, piles of leaves, wood chips and fallen trees are rapidly converted to soil by nematodes.  The whole question of added mass needs further research to more accurately determine the volume and sources.

Turbidite geological formations have their origins in turbidity current deposits, deposits from a form of underwater avalanche that are responsible for distributing vast amounts of clastic sediment into the deep ocean.

Torbay, despite being a built up area, has some spectacular Coast Path scenery and geology. Here the rocks were literally turned upside down by earth movements during a mountain building phase 280-300 million years ago. Large scale folding and faulting of the rocks can be seen around Thatcher Rock and Hopes Nose. At Meadfoot strange fossils in the limestone tell us about tropical reefs of the Devonian period. Around Goodrington, younger rocks that formed as the mountains were eroded in a hot arid environment, contain boulders and pebbles from the older limestones and shales. These red beds form the headlands at Livermead and Roundham Head. At Thatcher Point, just along from Hope's Nose, you can clearly see the hundreds of layers of limestone which were formed over millions of years - try the sites below.

It is a huge question, but in general you would want to check paleoclimatology (for example, glaciation of Antarctica after opening of Drake and Tasmania passages), paleontology/biogeography (distribution of fossils and ancient migration of various animal groups).\n\nThere is a page with lecture notes which is very shorthand but touches on most things you may want to check:\nhttp://jersey.uoregon.edu/~mstrick/RogueComCollege/RCC_Lectures/ConDrift_PlateTec.html\n\nAnother link that touches on the subject:\nhttp://pgap.uchicago.edu/PGAP2000-1.html

You need to have special circumstances to find sandstone on top of a conglomerate. Typically not a marine environment because oceans and waters for example rivers sort the sediments to different grain sizes dependant on the speed of the current. Conglomerates are UN sorted sediments of many grain sizes. a common place to find this is in an environment where there were glaciers, they could drop unsorted sediments and then as the glacier recedes the outwash from streams can deposit layers of sand above it. I suppose there can be plenty other environments for this kind of deposition but I would say this is the most common. But it is definitely not the result of the oceans transgressing or regressing.

You see there are different kinds of aeolians deposits.\nIf you look at the sites you will see different formations. You will see at the windward side erosion occurs, in where wind pick up sediments, like sand, and deposits it at the leeward side or simply at the back.

Structures resembling remarkably preserved bacterial and cyanobacterial microfossils from ~3,465-million-year-old Apex cherts of the Warrawoona Group in Western Australia currently provide the oldest morphological evidence for life on Earth and have been taken to support an early beginning for oxygen-producing photosynthesis. Eleven species of filamentous prokaryote, distinguished by shape and geometry, have been put forward as meeting the criteria required of authentic Archaean microfossils, and contrast with other microfossils dismissed as either unreliable or unreproducible. These structures are nearly a billion years older than putative cyanobacterial biomarkers, genomic arguments for cyanobacteria, and oxygenic atmosphere and any comparable diverse suite of microfossils. Here we report new research on the type and re-collected material, involving mapping, optical and electron microscopy, digital image analysis, micro-Raman spectroscopy and other geochemical techniques. We reinterpret the purported microfossil-like structure as secondary artefacts formed from amorphous graphite within multiple generations of metalliferous hydrothermal vein chert and volcanic glass. Although there is no support for primary biological morphology, a Fischer-Tropsch-type synthesis of carbon compounds and carbon isotopic fractionation is inferred for one of the oldest known hydrothermal systems on Earth.

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.
