Qapf Diagram. A qapf diagram is a double triangle diagram which is used to classify igneous rocks based on mineralogic composition. Geology is very complex natural processes are often impossible to observe metamorphism for example or take place very slowly.
A qapf diagram is a double ternary diagram which is used to classify igneous rocks based on mineralogic composition. Geology is very complex natural processes are often impossible to observe metamorphism for example or take place very slowly. The composition of the rocks are plotted into a diamond shaped coordinate system the qapf diagram also known as streckeisen diagram named after the author of the original article.

These are the mineral groups used for classification in qapf diagram. A qapf diagram is a double ternary diagram which is used to classify igneous rocks based on mineralogic composition. There are several reasons why this is the case. The acronym qapf stands for quartz alkali feldspar plagioclase feldspathoid foid.
