Carbon dating biogenic sediments

Dissolution rates are dependent upon the chemistry of the deep ocean waters through which the skeletal remains settle and of the bottom and interstitial waters in contact with the remains as they accumulate and are buried.

The chemistry of deep-sea waters, is, in turn, influenced by the rate of supply of both skeletal and organic remains of organisms from surface waters.

Non-marine as well as marine and terrestrial sediments can be dated using this method.

Each sample is prepared in the same way as for a micropalaeontological analysis.

Thus, associated gas was mostly flared (i.e., burned at the wellhead), and nonassociated gas was left in the ground, while town gas was manufactured for use in the cities.

Long-distance gas transmission became practical during the late 1920s because of further advances in technology.

For this reason associated gas is sometimes called “wet gas.” There are also reservoirs that contain gas and no oil. Nonassociated gas, coming from reservoirs that are not connected with any known source of liquid petroleum, is “dry gas.”Throughout the 19th century the use of natural gas remained localized because there was no way to transport large quantities of gas over long distances.Biogenic sediments, which are defined as containing at least 30% skeletal remains of marine organisms, cover approximately 62% of the deep ocean floor.Clay minerals make up most of the non-biogenic constituents of these sediments.It is also heavily dependent upon the rates of deep ocean circulation and the length of time that the bottom water has been accumulating CO Most carbonate or calcareous oozes are produced by the two different groups of organisms.The major constituents of nanofossil or coccolith ooze are tiny (less than 10 microns) calcareous plates produced by phytoplankton of the marine algal group, the Coccolithophoridae or by an extinct group called discoasters.

This work utilizes bulk and spatially-resolved X-ray absorption spectroscopy to characterize the OC content and composition of various environmental systems in order to identify the role of minerals and surrounding geochemistry in organic carbon preservation in sediments.
