Mineral Identification and Classification

The video tutorial explains how minerals are classified based on their chemical composition. It covers various types of minerals, including silicates, carbonates, halides, oxides, sulfides, sulfates, and native elements. The tutorial provides examples of each type and discusses their characteristics. It also includes a practice session for identifying minerals based on their composition.
