In 1986 he joined forces with Erich A . Colhoun to work together on the diatomite deposits at Marine Plain in the Vestfold Hills where the world-famous cetacean fossils were later found.

Medical-grade diatomite has been studied for its efficacy as a deworming agent in cattle; in both studies cited the groups being treated with diatomaceous earth did not fare any better than control groups.

During the Soviet period, a range of minerals was mined in Georgia, which included arsenic, barite, bentonite, coal, copper, diatomite, lead, manganese, zeolite, and zinc, among others.

The western end of the line was at Loch Cuithir, where diatomite-known locally as " Cailc " ( Scottish Gaelic for chalk )-was extracted from the lochbed and dried on wire nets.

Over 60 geoarchaeological sites bridging the Pleistocene-Holocene transition ( last deglaciation ) exhibit this " black mat "; it is a black organic-rich layer in the form of mollic paleosols, aquolls, and diatomites.

Tests of these tiny marine creatures form diatomite, and some of their organic remains persist as the high organic carbon content of parts of the formation ( when conditions are right, these organic remains form petroleum reservoirs ).

This remnant material is diatomite or " Diatomaceous earth ", and is used commercially as filters, mineral fillers, mechanical insecticide, in insulation material, anti-caking agents, as a fine abrasive, and other uses.

Besides molybdenum, Armenia has significant deposits of copper and gold; smaller deposits of lead, silver, and zinc; and deposits of industrial minerals, including basalt, diatomite, granite, gypsum, limestone, and perlite.

According to Haynes,'black mat'is a general term that also includes the similar other deposits of various shades of grey or even white, because some Younger Dryas marls and diatomites are actually white to grey in colour.

In terms of composition, the Ujina is pink-grey crystals and pumice and the Pastillos a gray-white pumice forming the lower member and the upper member of the Pastillos contains cinerites with accessory claystones, siltstones and diatomites.
