Qapf Intrusive. Diorite classification on qapf diagram mineral assemblage of igneous rocks diorite ˈ d aɪ. A qapf diagram is a double ternary diagram which is used to classify igneous rocks based on mineralogic composition.
The acronym qapf stands for quartz alkali feldspar plagioclase feldspathoid foid. ə ˌ r aɪ t 1 2 is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar typically andesine biotite hornblende and or pyroxene. The acronym qapf stands for quartz alkali feldspar plagioclase feldspathoid foid.
ə ˌ r aɪ t 1 2 is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar typically andesine biotite hornblende and or pyroxene.
ə ˌ r aɪ t 1 2 is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar typically andesine biotite hornblende and or pyroxene. The acronym qapf stands for quartz alkali feldspar plagioclase feldspathoid foid. These are the mineral groups used for classification in qapf diagram. This is an intrusive magmatic rock and is close to the very hot core of the world which is why it takes longer to cool and therefore the rock is visibly very different from the opposite of the basalt.
