Mineral Mineral Classifiion of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (, halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level ...
The chemical composition and microstructure of raw iron ore from the six hills of Muko deposit (Uganda) were investigated. According to the obtained results of Xray diffraction analysis, it can be concluded that all ore samples from Muko deposit were found to be mainly of a hematitic nature.
The composition of coconut kernel is commonly measured according to the percentage of oil in the kernel which is remarkably consistent across different coconut varieties.

Recent data on the chemical classifiion of ordinary chondrites are examined. Graphs are presented which serve to separate these chondrites into types H, L, and LL according to bulk chemical composition and mineral composition (pyroxene, olivine, kamacite). Examples of ordinary chondrites of other types are indied, along with anomalous meteorites that belong to this group of chondrites.
