Each of the three corners represents a particular component mineral (for example, A quartz, B plagioclase feldspar, and C potassium feldspar). If people have suggestions for further additions, I welcome this input, and as usual, if this package has assisted you in your work, please feel free to contribute to my beer fund via the donations link at the top of the page. WinFeldth evaluates eleven twofeldspar thermometers, nine two-feldspar thermometers based on the thermodynamic modelling of ternary solid solutions, six plagioclase-liquid thermometers, two. The above illustration is of a ternary diagram, which is a useful way of displaying abundances of three components which are constrained to add to 100. Labs(title='Demonstration of Raster Annotation') Geom_point(size=5,aes(shape=Feldspar,fill=Feldspar),color='black') + Theme_rgbw() + theme_nogrid() + theme_legend_position() +Īnnotation_raster_tern(FeldsparRaster,xmin=0,xmax=1,ymin=0,ymax=1) + Examples of three end-member systems include percent sand-silt-clay in soil samples, percent quartz-feldspar-lithic fragments in sandstone samples, and alkali. Please cite as: Iacovino, Kayla, & Gouard, Cdric. Created using coordinates as given in Le Maitre et al (2002). Included in this ggtern 2.1.1 is raster-array data for Figure 6 from Elkins and Groves Feldspar, lets dive in and demonstrate how to overlay some fresh points over this existing figure, for the sake of convenience, lets use the data from the same paper for the points themselves.: Excel spreadsheet that allows for fast plotting onto a TAS (total alkali silica) diagram for use in naming your volcanic rock by composition. Several people have asked me how they can overlay their new data over the top of an existing ternary diagram, say from a publication and the like. This post will demonstrate the use of this requested feature. textures based on a bulk composition on 2 different ternary diagrams.

This includes a number of minor bug fixes, and an additional annotation, permitting the rendering of raster data, say for the inclusion of images. Hi Folks, ggtern v2.1.1 has just been submitted to CRAN.
