QAPF diagram for classification of plutonic rocks. A QAPF diagram is a doubled-triangle plot diagram used to classify intrusive igneous rocks based on their mineralogy. The acronym QAPF stands for "Quartz, Alkali feldspar, Plagioclase, Feldspathoid (Foid)", which are the four mineral groups used for classification in a QAPF diagram. The ...
A ternary flammability diagram, showing which mixtures of methane, oxygen gas, and inert nitrogen gas will burn. A ternary plot, ternary graph, triangle plot, simplex plot, or Gibbs triangle is a barycentric plot on three variables which sum to a constant. [1] It graphically depicts the ratios of the three variables as positions in an ...
Ternary diagram showing the relative abundance of quartz, feldspar, and lithic grains and views of what selected compositions would look like. A QFL diagram or QFL triangle is a type of ternary diagram that shows compositional data from sandstones and modern sands, point counted using the Gazzi-Dickinson method. The abbreviations used are as ...
A three-component compatibility diagram will depict the stable phase of each pure component as the point at each corner of a ternary diagram. Additional points in the diagram represent other pure phases, and lines connecting pairs of these points represent compositions at which the two phases are the only phases present.
Ternary logic, a logic system with the values true, false, and some other value; Ternary plot or ternary graph, a plot that shows the ratios of three proportions; Ternary relation, a finitary relation in which the number of places in the relation is three; Ternary operation, an operation that takes three parameters
English: An empty ternary plot: i.e. 'blank graph paper' for a ternary diagram / phase diagram, with axis labels perpendicular to each plotting axis to facilitate plotting and comprehension. Arrows parallel to each side indicate direction of increase for each of the three dimensions.
For a representation of ternary equilibria a three-dimensional phase diagram is required. Often such a diagram is drawn with the composition as a horizontal plane and the temperature on an axis perpendicular to this plane. To represent composition in a ternary system an equilateral triangle is used, called Gibbs triangle (see also Ternary plot).
Derivation of ternary plots from Cartesian coordinates: Image title: Derivation of ternary plots from Cartesian coordinates, drawn by CMG Lee. (1) shows a point P(a,b,c) in a 3-dimensional Cartesian plane. In (2), if a + b + c = K, and a, b and c are non-negative, P is restricted to the triangle bounded by A, B and C.
