What is Triangular Graph Paper?



Triangular graph paper is used to graph the relationships between three variables on an equilateral triangle. This type of two-dimensional graph can be made when the sum of the three variables always adds up to a constant - usually 100% or 1. The charts produced from this method of graphing are generally referred to as "ternary plots" or "ternary diagrams". They are frequently used to plot the compositions of mixtures in physical chemistry, petrology, mineralogy, metallurgy and other physical sciences. Ternary plots are also used in genetics and game theory.


Plotting Example



In petrology, plutonic igneous rocks are classified by the relative abundance of quartz (Q), plagioclase (P) and alkali feldspar (A) in their composition. A field classification chart is shown below. By this chart rocks that contain greater than 60% quartz are known as "quartz-rich granitoids", those that contain between 20% and 60% quartz are known as "granitoids". Those that contain less than 20% quartz and are rich in alkali feldspar are known as "syenitoids". Other rocks are either dioritoids, gabbroids or anorthosites.

Two red points are plotted on the chart. One is at a composition of 50% quartz, 40% alkali feldspar and 10% plagioclase. That composition makes the rock a "granitoid". Another rock plots at 10% quartz, 40% alkali feldspar and 50% plagioclase, making the rock a "syenitoid".


About our Triangular Graph Paper



We have two types of triangular graph paper, one with black lines and one with blue. Choose the paper that will contrast with the pencil or pen color that you will be plotting with. These papers are provided as printable .pdf documents. They are designed to print on a standard sheet of 8 x 11 paper. They can be opened and printed with a .pdf document reader such as Adobe Reader.
