I have a science project for school and I had to pick ten minerals and write down the color, luster, texture, streak, etc and then I have to answer a few questions about it. The last one says to classify the minerals into at least three groups. How do I do it? I‘m not asking for the answer, I just need a general idea of how to do it. Thanks x
they are usually classified by their chemical composition. Like metal ores galena lead hematite iron sphalerite zinc scheelite tungsten silicates mica feldspar hornblende tourmaline non-silicate, not metal ores calcite dolomite gypsum
