In this video, I introduce the "Soil Texture Ternary Diagram" and do two examples on how to plot a soil texture value on the ternary diagram. Let's assume you have three variables, A = 42.5%, B = 25.5%, and C = 17%.
for a specimen plotted at "A" How to read a ternary diagram? A ternary diagram consists of an equilateral triangle of which the apices represent 100% and the opposite base/side 0% of each variable.
To name a clastic sedimentary rock we must plot the composition on the QFL diagram, and the texture on the texture diagram, and then combine the two to get the full name. Go to all ternary diagrams combined into one diagram. And you need to do this for all possible pairs. The way to read the relationship is to always isolate 2 out of the 3 participating entities and see how they relate towards the third one. Notes Assume the ternary relationship has participating entities A, B and C (for degree > 3 it gets pretty hairy). Click the Scale tab and set Rescale mode. Beginning with Origin 2021, you can control the Rescale mode of the graph axes: Double click on an axis to open the Axis dialog for ternary diagrams. Go to the Ternary tab, and choose either the Counter Clockwise or Clockwise radio button to set the axis direction. It allows to see how the points cover the space and to detect potential zones that should be explored in further experiments. Interpreting a ternary diagram After you have clicked on the OK button, the ternary diagram is displayed on a new Excel sheet (because the Sheet option has been selected for outputs). Usually have elements at the corners as the constituents, Know binaries! Useful books Understanding Phase Diagrams - V.B. The mass fraction of a component in the mixture i Ternary Phase Diagrams Lesley Cornish. Each corner of the triangle corresponds to a pure component. Move the black dot to any location within the triangle by clicking on that location which represents the overall composition of the mixture. (iii) This Demonstration shows two representations of a ternary phase diagram which is used to represent the phase behavior of three-component mixtures. These are single-phase homogeneous phases. (ii) Beginning from each vertex, label areas of the triangle that extend up to any of the boundaries as L1, L2 or V as appropriate. Steps for assigning phases on ternary diagrams (i) Assign each substance or compound a unique designation such as L1, L2 or V for a supercritical phase or a vapor phase.
