See TAS diagram below to see how these rock types differ in their chemistry. Trachyte is a volcanic equivalent of syenite. Syenite is a feldspar-rich plutonic rock which is similar to granite but lacks or contains very little quartz. Mafic minerals in trachyte are usually biotite, ... In the "Params" sheet, all coordinates used to determine the different areas of the TAS Diagram are reported. Row 33 contains the %SiO2 values, rows 3-32 contain the %(Na20+K2O). This plot has editable values, in case you wish to change the rocks fields. In the "Backstage" sheet, every field is sampled to identify where in the chart the sample falls.

The use of TAS diagram is very simple and straightforward. You only need to know the major element chemical composition of the rock sample being studied. There are SiO 2 on the x-axis and the sum of K 2 O and Na 2 O on the y-axis. TAS stands for Total Alkali Silica. Here are the coordinates of the intersections.

2. Data Input. Geochemical data can be imported into PetroGraph in three file formats (): (1) MS Excel® worksheets, (2) IgPetWin® formatted files, and (3) PetroGraph (.peg) files.MS Excel® worksheets need little formatting before imported to PetroGraph, as reported in Figure 2.The arrangement of the worksheet, however, is not much different from common analytical outputs.

Winrock Lesson3 Plotting Spider and TAS Diagrams. *Please note that all the ternary diagrams were constructed in the Excel package Ternplot (Marshall, 1996). Acknowledge the use of this program. I found the following while doing a Google search for an uncomplicated table showing conversions of IAS to TAS at different altitudes. It is not offered by the author as a highly precise table, in which every minute factor is calculated into the conversion speeds, but a "ready-reckoner." I find it useful -- perhaps others may, too. At 5,000' TAS = IAS + 9% At 10,000' TAS = IAS + 16% At 15,000 ...

QAPF diagrams are mostly used to classify plutonic rocks (phaneritic rocks), but are also used to classifyvolcanic rocks if modal mineralogical compositions have been determined. 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) is used.
