What is the chemical formula for slate?

Answer 1

There is no specific or universal chemical formula for slate, because slate is formed up of various amounts of varying types of rock such as:

• Quartz
• Muscovite
• Illite
• Biotite
• Chlorite
• Hematite
• Pyrite
• Apatite
• Graphite
• Kaolin
• Magnetite

In some locations, such as the mountains of Wales, slate also contains iron.

The chemical formula for slate is primarily composed of silicate minerals, such as quartz, feldspar, and mica. However, since slate is a metamorphic rock formed from shale or clay, its exact chemical composition can vary depending on the specific minerals present in the parent rock.
