QAPF diagram for plutonic rocks. The diagram was created by the Subcommission of the Systematics of Igneous Rocks in the latter part of the 20th century. There are several reasons why this is the case. Geology is very complex, natural processes are often impossible to observe (metamorphism for example) or take place very slowly Triangle diagrams in Excel! Template. Triangle outline coordinates More sample coordinates Makes sure sum = 100 Raw coordinates Plot these columns Intermediate calcs Raw sample data Preliminary values go in these columns Change only these three columns Don't change these columns Don't change these columns either Step 1 . The acronym, QAPF, stands for Quartz, Alkali feldspar, Plagioclase, Feldspathoid (Foid). These are the mineral groups used for classification in QAPF diagram Ternary Plot on MS Excel Rock ComponentsFile was update: https://youtu.be/ioqYMonfvhcLink to download the file is on the new video WinRock plots IUGS igneous classification diagrams, including QAPF diagrams, plus sandstone, general purpose XY, pie, log, and ternary diagrams.

QAPF diagram and TAS diagram are based on different criteria. There is absolutely no guarantee that a rock sample which was correctly identified as trachyte using QAPF diagram is still trachyte if we make a chemical analysis of it and plot the results on the TAS diagram. But this is the reality we have to live with right now To plot the QAPF you actually need the normalized modal mineralogy of Quartz, Alkali-feldspar, Plagioclase, and Feldsparthoids. Your data is normative mineralogy, so they must be plotted on variation and TAS diagrams. You can do a CIPW norm calculation to infer modal mineralogy and then use that for in a QAPF
The AFM diagram is a triangular plot with apices A, F and M deﬁned as follows: A = (K 2O+ Na 2O) wt. % F = FeOtot wt. % M = MgO wt. % A + F + M = 100 % The classiﬁcation diagram divides data into 'tholeiite series' and 'calc-alkaline series' as proposed by Irvine & Baragar (1971) The QAPF and related diagrams are intended for classification of rocks in the field, or preliminary classification with modal proportions as seen in the optical microscope. They are not designed with the chemical composition of the rocks in the mind. Furthermore, these diagrams are merely descriptive and not genetic
Gracias a esto el diagrama STRECKEISEN o QAPF es actualmente el diagrama más empleado en la denominación de las rocas ígneas. Con esta pequeña utilidad podremos determinar mediante el uso de la PC los distintos tipos de rocas ígneas de manera bastante fácil y encontrar de esta manera, la denominación de las rocas plutónicas y volcánicas como solíamos hacerlo de forma manual. Place a regression line on it, and include the diagram in your report by describing what the data show. 2) Plot: IUGS, TAS LeBas diagram.

Plotting Onto a Ternary Diagram. Ternary diagrams make the assumption that the three variables plotted make up 100% of the sample. Before you can plot a data point (say, A = 700, B = 200, and C = 100) you. The diagrams below are those I have used, or tried to use, at one time or another. I had to figure out the discriminant line coordinates so that I could plot my data on them. It is a senseless waste of time for everyone else to have to do the same thing, so I present the coordinates for the benefit of all humanity
O diagram for classification of magmatic series proposed by Peccerillo and Taylor (1976), most of granites belong to high potassium calc-alkaline series Fig. (10). Figure 7 Figure The QAPF diagram with plotted data of igneous rocks of the study area (Source: IUGS classification, 2006). 8 Classification of igneous rocks b ACF Diagrams. One of the first uses of these types of diagrams was by Eskola (1915) who employed a diagram known as the ACF diagram in his study of metamorphic rocks. To plot a rock on the ACF diagram, the chemical analysis of the rock is first recalculated to molecular proportions by dividing the molecular weight of each oxide constituent by. A ternary plot, ternary graph, triangle plot, simplex plot, Gibbs triangle or de Finetti diagram is a barycentric plot on three variables which sum to a constant. Oct 23, 2020 · Type (or paste) your data in the Excel compatible spreadsheet on the left and symbols will popup in the triangle and the legend
The normative calculation is a way to take an aphanitic or glassy volcanic rock (which lacks the crystalline assemblages that lend themselves to QAPF diagrams), and use it's major-element chemistry to calculate an idealized mineralogy. (Basically it's Accounting meets Geology) One way this approach is useful is that it allows to examine a fine. Spreadsheet reports can be generated in order to quickly export bulk data for multiple samples to programs such as Microsoft Excel. Triangular and double triangular (QAPF) diagrams can be constructed within the software, with a range of preinstalled schemes available. Additional schemes can also be imported by the user 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. Determine the percentage, called the mode, of quartz (Q), alkali feldspar (A), plagioclase feldspar (P), and mafic. It would be rational to routinely use the QAPF diagram, together with supplementary modal diagrams for the gabbroic and ultra- mafic rocks (p. 18-21), in the classification of the main sequence plutonic rocks, and the TAS diagram in the classification of the main sequence volcanic rocks

Diorite A plutonic rock defined in the QAPF diagram as having Q between 0 and 5% or F/(F+A+P) < 10%, P/(A+P) greater than 90% and plagioclase more sodic than An50
A ternary plot, ternary graph, triangle plot, simplex plot, Gibbs triangle or de Finetti diagram is a barycentric plot on three variables which sum to a constant. It graphically depicts the ratios of the three variables as positions in an equilateral triangle.It is used in physical chemistry, petrology, mineralogy, metallurgy, and other physical sciences to show the compositions of systems. the TAS diagram, both for volcanic (Le Bas et al., 1986) and plutonic (Cox et al., 1979) rocks. The IUGS recommendations for plutonic rock nomenclature, such as the use of the QAPF double-triangle, cannot be followed. Further, it is not clear if the program allows for the prior adjustment of measured compositions on an anhydrous basis The diagram on the right is a P-T phase diagram, showing the relative stability fields of the Al 2 SiO 5 polymorphs. Petrology deals extensively with phase equilibrium and phase diagrams, and we will be seeing many such diagrams in subsequent chapters
