Kayaç türü listesi

aşağıda, jeologlar tarafından tanımlanmış kayaç türlerinin bir listesi bulunmaktadır. kararlaştırılan sayıda belli kayaç türleri yoktur. kimyasal bileşim, mineraloji, tane boyutu, doku veya diğer ayırt edici özelliklerin herhangi bir benzersiz kombinasyonu, yeni bir kayaç türüne işaret edebilir. ek olarak, her ana kayaç türü için farklı sınıflandırma sistemleri bulunur. magmatik kayaç, metamorfik kayaç ve tortul kayaç olmak üzere üç ana kayaç türü vardır.
