A new version of TriAngle is now ready for download at the TriAngle sub page.

New feature:
In comparison to other Excel spreadsheets for triangular plots, TriAngle offers the user the opportunity to design individual masks by simply inserting the required plotting coordinates in the pre-defined fields in the ‘Template’ worksheet. TriAngle calculates the resulting X-Y-coordinates and draws the mask.
Labels can be inserted in the same way, too.
A manual how to create individual masks and labels is shown in the worksheet ‘Manual’.

TriAngle is a Microsoft Excel^TM spreadsheet template to create triangular plots in an easy way.

Features:

1. Simple to handle

3. No use of VBA; to adapt easily the file to other desktop and mobile spreadsheet programs which do not support VBA
4. Automatic display of apexes titles
5. Automatic display of a legend (can be deleted if not desired)
6. Selection of typical masks used in the daily business of geoscientists – the user has the chance to add own masks

The mineralogical and chemical characteristics of Palaeozoic rocks in the northern Eifel Mountains provide information on the sedimentary provenance in the NW Rhenohercynian Basin and on the mineralogical and hydrothermal control of trace element abundance. Elements mainly bound to illite (i.e. V, Ni, Rb, Sr, Cu, Ba) can be distinguished from elements predominantly controlled by chromite (Cr) and zircon (Zr). Lower Devonian and Upper Carboniferous units have similar …
