How to Identify Chert Sedimentary Rock Like a Geologist #rocks #identification #geology #rocktypes

Hi Rockhounds. Let’s identify Chert. Chert is a sedimentary rock that is typically gray or white, light shades of red, yellow, and brown in color. Identifying Chert sedimentary rocks is fun when you learn how geologists use different properties of the rock to determine its name. You can learn to identify rocks like Chert using color, texture, and mineral content.

Chert is a cryptocrystalline form of quartz that forms as nodules and layers in other sedimentary rocks such as dolomite, limestone, and chalk. Chert is used to make firearms, prehistoric arrowheads, tools, and headstones. Chert may contain fossils and it will spark if you hit it with a hammer. Tracy Jones, the professional geologist at Mini Me Geology is ready to show you examples of Chert rocks and teach you how to identify the rocks in your collection.
