Authigenic Minerals

Authigenic minerals are minerals that form in place within sedimentary rocks or sediments, rather than being transported from elsewhere. They develop through chemical processes, often due to changes in temperature, pressure, or the surrounding environment. These minerals can provide valuable insights into the conditions present during rock formation, such as past climates or the chemical makeup of ancient waters. Common examples include clay minerals and certain types of quartz. Understanding authigenic minerals can help geologists reconstruct geological histories and assess natural resources like oil and gas.
