Pure silex 15 grains.
Pure alumina, or the earth of clay 11 grains.
Oxide (rust) of iron 3 grains.

Magnesium Carbonate material in the core has in some instances been converted to glass (this is very rare but was first produced by the writer in an implosion tube experiment).
Calcium carbonate deposits which form in caves and around hot springs where carbonate-bearing waters are exposed to the air. The water evaporates, leaving a small deposit of calcium carbonate.

In soils where negligible calcium carbonate is present, as was the case here, total carbon provides a measure of organic carbon held in the soil relating to biomass (e.g. microbial, macrobial, humus, plant material).
In tropical regions in particular, plants and animals not only affect the weathering of rocks but are a source of sediment themselves. The shells and skeletons of many organisms are of calcium carbonate and when this is broken down it forms sediment, ...
