Qapf Diagram

Qapf Diagram A qapf diagram is a plot diagram used to classify igneous rocks based on their mineralogy. it shows the proportions of quartz, alkali feldspar, plagioclase, and feldspathoid groups, normalized to 100%. 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.

Qapf Diagram 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)". 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 used to classify plutonic rocks. 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. Qapf diagram is a program that creates ternary graphs and classifies igneous rocks based on mineral abundance data from rockworks datasheet. it can plot qap, qapf, and qapf mafics diagrams and switch between plutonic and volcanic terminology.

Qapf diagram is a program that creates ternary graphs and classifies igneous rocks based on mineral abundance data from rockworks datasheet. it can plot qap, qapf, and qapf mafics diagrams and switch between plutonic and volcanic terminology. Qapf diagram is a diamond shaped coordinate system that plots the composition of igneous rocks by their content of quartz, alkali feldspar, plagioclase and foids. it is used to classify rocks into 15 basic fields based on their mineralogy and texture, and to distinguish plutonic and volcanic rocks. The template will plot modal compositional data of igneous rocks into qapf and triangular diagrams, including diagrams for mafic and ultramafic rocks, according to the usgs nomenclature. Learn how to use the qapf diagram, a petrological tool that divides volcanic rocks into four groups based on the percentage of quartz, alkali feldspar, plagioclase feldspar, and feldspathoid. see examples of andesite, rhyolite, basalt, and other rock types and their positions on the diagram. The acronym, qapf, stands for "quartz, alkali feldspar, plagioclase, feldspathoid (foid)". these are the mineral groups used for classification in qapf diagram. q, .a, p and f percentages are normalized (recalculated so that their sum is 100%) qapf diagrams are mostly used to classify plutonic rocks (phaneritic rocks) (figure 1), but are.
