Mineralogy
Dexter Perkins et al. · University of North Dakota
Minerals are our planet. They form the Earth and the bedrock that we live on, making up all of Earth’s rocks and sediments, and they are important components in soils. So, they literally are the foundations for our lives. Perhaps because they are ubiquitous, most people don’t even notice them or consider that all rock is made of minerals.
