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)". These are the mineral groups used for classification in QAPF diagram.

Peridotite. Peridotite is a dark-colored igneous rock consisting mostly of olivine and pyroxene. It is an important rock type because the Earth's mantle is predominantly composed of it. A classification diagram of ultramafic rocks. Note that neither peridotite nor pyroxenite are single rock types.

Once data have been imported, the user can visualize them using three different types of diagrams commonly used in igneous petrology: binary, ternary, and spider diagrams . All diagrams can be easily generated in few steps. For example, a binary or a ternary diagram can be created in only 3 steps as described in Figure 3. Several options are ...

This can be illustrated in the feldspar compositional ternary diagram. Feldspar minerals are the most abundant constituents of igneous rocks. Despite being sensitive to weathering and alteration, feldspars are abundant (second after quartz) in arenaceous sedimentary rocks, either in form of detrital grains or as secondary, authigenic phases.

This activity takes place in a laboratory setting and requires ~1.5-2 hours to complete. Students observe igneous rock compositions and plot them on triangle diagrams, normalize rock compositions using a spreadsheet, and identify the rocks.

ESS 210 Lab 6: Igneous Rock Identification . Ternary classification of felsic to mafic igneous rocks. The top diagram is for extrusive rocks and the lower is for intrusive rocks. Note that rocks with glassy or pyroclastic textures may be described by the above compositions, but that for these specimens the final rock name must still ...

A: In general you can plot any sort of boundaries and/or labels you want with a ternary plot (aka triangle plot, depending on what world you work in), and your "but the line disappears" is easily explained. But more on that below. First, yes you can plot mafic and ultramafic rock classifications starting with version 2.2.6.

Igneous rocks are those that form via the process of melting and cooling. If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks.By contrast, Intrusive rocks are formed from magma that cools underground. If the intrusive rock cooled underground but near the surface, it is called subvolcanic or hypabyssal, and often has visible, but tiny mineral grains.

Like igneous rocks, most metamorphic rocks are composed of 9 or more major elements. Thus, initially it would appear that we are dealing with a 9 or 10 component system. Recall, however, that the number of components in any given system is the minimum number required to define the composition of all phases in the system.

These features make rock classification difficult and undermine its quality, thereby negatively impacting geological conclusions and mineral exploration results. A novel alternative procedure for igneous rock classification involves using whole rock lithogeochemical data for classification on Streckeisen ternary diagrams.

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. Here is how it works:

The classification of igneous rocks is largely based on two diagrams: QAPF diagram for plutonic rocks (formed in the crust) and TAS diagram for volcanic rocks. I made the schemes using the coordinates provided in the following book: Le Maitre, R. W.

Finding what is the norm of the rock. A norm is an estimation of the ideal mineralogy of an igneous rock, based on the chemical composition of the rock. The most common norm calculation method is the CIPW norm, but there are other methods as well. For starters you should do fine with the norm.

Lithogeochemical classification of igneous rocks using ...

These mineral mode estimates can then be plotted on (projected onto) Streckeisen ternary diagrams, to classify the rocks in the normal manner. This new approach has advantages over conventional classification strategies, in that it is relatively inexpensive, adaptable to all forms of igneous rocks, quantitative, accurate, and precise.

Ultramafic rocks containing hornblende, a type of calcium amphibole, are very rare on Earth, but they are found in some mafic and ultramafic complexes as a result of igneous processes that are currently poorly understood. These rocks can be classified using the olivine - pyroxene - hornblende (Ol - Px - Hbl) ternary diagram, where Px ...
