What is a Rock and What are 3 Basic Types of Rocks

Rocks formation takes different processes. Their formations are classified according to the rock types since the processes involved normally results in a characteristic relationship between the mineral grains. Rock formations, therefore, are in three basic groups which include igneous, sedimentary, and metamorphic. 1. Igneous Rocks

Mineral Groups – Physical Geology

Mineral Groups Most minerals are made up of a cation (a positively charged ion) or several cations and an anion (a negatively charged ion (, S 2–)) or an anion complex (, SO 4 2–). For example, in the mineral hematite (Fe 2 O 3), the cation is Fe 3 + (iron) and the anion is O 2– (oxygen). We group minerals into classes on the basis of their predominant anion or anion group.
