Approximately 4,000 different minerals are recognized by the International Mineralogical Association, each with unique properties and its own set of descriptive keywords. Understanding what are the keywords for minerals is fundamental to studying geology, collecting specimens, and appreciating their economic value.

Over 4,000 different mineral species exist on Earth, each with a unique set of properties. Understanding the major features of the minerals is crucial for geologists and anyone interested in the natural world, as these characteristics determine a mineral's identity, formation, and uses. This guide will explain the key characteristics that define a mineral.

As of May 2025, the International Mineralogical Association (IMA) officially recognizes 6,145 unique mineral species, though that number continues to grow as new discoveries are made. This figure answers the question of how many different kinds of minerals are there, but the full story is far more complex, involving different classification systems and definitions.

Silicate minerals constitute over 90% of the Earth's crust. Understanding their systematic arrangement helps explain what is the classification of minerals in detail, a field centered on chemical composition and crystalline structure. Mineral classification is a critical tool for geologists and researchers to organize and understand the vast diversity of inorganic compounds that make up our planet.

The vast majority of Earth's crust, over 90%, is composed of just one mineral group: the silicates. Mineralogy, the scientific study of minerals, classifies these naturally occurring inorganic solids primarily based on their chemical composition, which organizes the thousands of known mineral types into distinct classes. Understanding what are the four major groups of minerals provides a fundamental framework for comprehending geology.

The Mohs hardness scale, a simple yet effective tool for mineral identification, uses a ranking of 1 to 10 to measure scratch resistance. At the seventh position on this scale sits quartz, a mineral so common and widespread that it is found in nearly every type of geological environment.

According to the U.S. Geological Survey, the Earth's crust is composed of over 90% silicate minerals, with an estimated 60% consisting of feldspar and 12% being quartz. This makes feldspar and quartz the two main minerals on Earth, dominating the composition of rocks and soils across the globe.
