The video tutorial explains how geologists classify minerals into groups based on their chemical makeup and physical properties. It introduces the two main groups: silicate minerals, which contain silicon, and non-silicate minerals, which do not. Examples of each type are provided, such as quartz and feldspar for silicates, and sulfur and calcite for non-silicates. Additionally, minerals are categorized as metallic or non-metallic, with examples like galena and copper for metallic, and halite and calcite for non-metallic.
