tectonicr

tectonicr is a free and open-source R package for modeling and analyzing the direction of the maximum horizontal stress (SHmax) based on the empirical link between the orientation of intraplate stress and the direction of the relative motion of neighboring plates. You can download and install it directly from the CRAN server using install.packages("tectonicr") in R. A beta version is on Github. There is also tutorial and step-by-step guide.

structr

Structural geology package for R, free and open-source. It provides functions to

• analyze and visualize orientation data of structural geology.

• analyze stress (including visualization of the magnitudes of stress in the Mohr Circle).

• reconstruct the orientation of structures in oriented drill cores using the alpha, beta, and gamma angles.

ptrotR

A free and open-source R package for analysing and reconstructing plate motion. It reads GPLATES *.rot files, i.e. a sequence of total reconstruction poles, that can analysed (e.g. extraction of stage poles).

Theriak-Domino helpers

Web-application providing little helper functions to handle THERIAK DOMINO files

• Therin Generator: Calculates the molar units given a bulk compositions (wt. %) and generates the THERIN input for Theriak-Domino

• GUZZLER table filter: Extracts minerals from the GUZZLER reaction table
