1. Chemical classification of rocks involves analyzing which aspect?Color Structural features Mineral composition HardnessAnswerThe correct answer is: C) Mineral compositionExplanationThe chemical characteristics of rocks are determined by their mineral composition, which also serves as the basis for their ...
The "flexible sorting strategy" of Lance and Williams , and the " Gower metric" are successfully used for the classification of associations. Eight taxa of igneous rock associations have been established and these are in good agreement with the concept of petrochemical provinces....
