Qapf Mineraologic Classification Of Igneous Rocks Diagram Quizlet Start studying qapf mineraologic classification of igneous rocks. learn vocabulary, terms, and more with flashcards, games, and other study tools. This qapf diagram is two independent ternary diagrams that share the a p edge. the upper triangle has the corners a q p, where a is alkali feldspar, q is quartz, and p is plagioclase.
Classification Of Igneous Rocks Diagram Quizlet A qapf diagram is a doubled triangle plot diagram used to classify igneous rocks based on their mineralogy. the acronym qapf stands for " quartz, alkali feldspar, plagioclase, feldspathoid (foid)", which are the four mineral groups used for classification in a qapf diagram. Although similar diagram exists for volcanic rocks as well but because volcanic rocks are typically too fine grained for mineralogical analysis, they are classified according to their chemistry and tas diagram is used instead of qapf diagram. Iugs diagram for naming plutonic phaneritic igneous rocks with an>50. this qapf diagram is two independent ternary diagrams that share the a p edge. the upper triangle has the corners a q p, where a is a lkali feldspar, q is q uartz, and p is p lagioclase. Qapf diagram is a double triangle diagram which is used to classify igneous rocks based on mineralogic composition. the acronym, qapf, stands for "quartz, alkali feldspar, plagioclase, feldspathoid (foid)".

Qapf diagram is a double triangle diagram which is used to classify igneous rocks based on mineralogic composition. the acronym, qapf, stands for "quartz, alkali feldspar, plagioclase, feldspathoid (foid)". The qap ternary diagram is used to classify igneous rocks with visible mineral grains (phaneritic texture) from their feldspar and quartz content. in plutonic rocks, all of the minerals are crystallized into visible grains. The program will also classify the input samples based on igneous rock categories depicted within the diagrams and save these classifications within the same datasheet (figure 3: far right column). Qapf diagrams are not used to classify pyroclastic rocks or volcanic rocks if modal mineralogical composition is not determined, instead the tas classification (total alkali silica). A qapf diagram is a double triangle diagram which is used to classify igneous rocks based on mineralogic composition. the acronym, qapf, stands for " quartz, alkali feldspar, plagioclase, feldspathoid (foid)".
