The radioactive element uranium is well-known for its role in nuclear energy. People mine naturally occurring uranium from deep sandstone deposits called roll fronts. Scientists have long thought that abiotic chemical reactions that occur over millions of years resulted in formation of crystalline uranium. An international team of scientists has challenged …

We’re going far afield for chemistry news this morning: all the way to Mars. As many readers will have seen, there’s some very interesting (and long-awaited) news – deposits of organic compounds have been conclusively identified. (Here’s the paper, free full text). This really is of great ...
A new twist on uranium's origin story Mineral deposits in Wyoming have revealed a new form of biologically produced uranium Date: June 1, 2017 Source: Colorado State University Summary: Biogeochemists found biogenic, non-crystalline uranium occurring naturally in a Wyoming roll front, offering new clues to the mineral's origins. Share: …

GC8006. Distribution and Significance of Coarse Biogenic and Clastic Deposits on the Texas Inner Shelf, by R. A. Morton and C. D. Winker. 15 p., 7 figs., 2 tables, 1980.
Biogenic deposits are fine-grained red, brown or light-colored skeletal remains of planktonic organisms that have been deposited on the ocean floor.
Temperate Reefs, Seagrass Meadows, and Other Features. The buildup of biogenic sediment produces a variety of mound-shaped, tropical, and also nontropical deposits formed mainly of biologically produced sediment (known as bioherms) that occur on temperate to polar continental shelves.
order to reconstruct the main stages in the sedimentation of biogenic deposits, we have used stratigraphic variability of selected litho-geochemical elements (organic matter, calcium carbonate, biogenic and terrigenous silica, macro- and
3.7 Origin: Biogenic vs. Thermogenic . The origin of the encaged gas may be indicative of the distance of upward migration of the gas before it became a part of a clathrate hydrate.
SEDIMENTARY ROCKS. Prepared by T. Weiland for GEOL 1121. Sedimentary rocks - rocks formed by the accumulation and consolidation of sediments (surficial processes).. I.

Biogenic ooze: Biogenic ooze, any pelagic sediment that contains more than 30 percent skeletal material. These sediments can be made up of either carbonate (or calcareous) ooze or siliceous ooze. The skeletal material in carbonate oozes is calcium carbonate usually in the form of the mineral calcite but sometimes
Thick sediment deposits found at the foot of the continental slope, depths as great as 5km. Caused by turbidity currents, underwater landslides. Sometimes started by the shaking of earthquakes- rush up to 90km/h- slows down and deposits this sediment . Calcareous ooze. biogenic sediment on seafloor that is made of calcium carbonate …
