Web11 Nov 2024 · Under Plagioclase Feldspars there should be Anorthite. It is one of the most common rock bearing minerals in the entire world. It is something students will prep for especially with “feldspar ternary diagrams” as a topic in a different section. In fact, the ternary diagram is described by % anorthite (%An). Description: WebA 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)". These are the mineral groups used for classification in QAPF diagram. Q, A, P and F percentages are normalized (recalculated so that ...

WebThe equation would convert the data to x-y coordinates which I could plot on a standard graph. I would hide the axis, labels and put a blank ternary diagram in the background, over which my data would be plotted. The equations I used were: x=C÷SIN (RADIANS (60))+A÷TAN (RADIANS (60)))×SIN (RADIANS (60) y=A×SIN (RADIANS (60)) For a,b, and c ... http://www.ggtern.com/category/example/
WebFor comparison, I have added R.L. Folk’s 1966 classification of terrigenous sandstones (from Folk, 1968, Petrology of Sedimentary Rocks ). In this scheme, sand-dominated rocks and sediments carrying less than 15% matrix are called arenites; those with 15-75% matrix are wackes, and >75% matrix, mudstones. Note that the percentage matrix is ...
