This freeware can be used for correction of brightness irregularities (shadows) on SEM images (mostly BSE images) of flat samples...


TWQ_CombTWQ_Comb is a ©MS Windows freeware for automatic generation of all possible combinations of selected microprobe analyses and for their processing by the CMP.EXE and TWQ.EXE programs (from the TWQ package of R.G. Berman et al.) running in the batch mode...


TWQ_ViewTWQ_View is a handy ©MS Windows freeware for viewing and basic work with diagrams generated by the TWQ program of R.G. Berman, T.H. Brown, E.H. Perkins and J. Ellwood...


Drawpd2TVLDrawpd2TVL is a ©MS Windows freeware that can be used to convert THERMOCALC output files into phase diagrams. It is a replacement for the standard Drawpd program included in the THERMOCALC package.



TC_Comb is a wrapper for the THERMOCALC program of R. Powell and T. Holland running in multi-equilibrium geothermobarometry modes (only avPT+Reactions now). This program can make THERMOCALC geothermobarometry more effective and comfortable.


PTQ_Avg logo

PTQ_Avg is a supplementary program for PTQuick which calculates "simple averages": the points with shortest root-mean-squared distances to all the lines plotted on 2D diagrams.


PTQ_Comb logo

PTQ_Comb is a small program which generates combinations of mineral analyses for geothermobarometric investigations with PTQuick...


XFluid logoYou can use this small and simple freeware program to calculate compositions of C-O-H fluid at pressures from 1 bar to 100 kbar and temperatures from 400°C to 2300°C for many samples at once, according to: Zhang, C., Duan, Z.H., 2009. A model for C–O–H fluid in the Earth’s mantle // Geochimica et Cosmochimica Acta, V. 73, pp. 2089–2102...


PTQuick logoPTQuick is a handy ©MS Windows program for estimation of equilibrium parameters (temperatures, pressures, oxygen fugacities) for mineral parageneses using methods of classical geothermobarometry, i.e. by independent expressions and algorithms ("tools") developed by different authors...


ReactionsReactions is a small handy freeware for generation of all possible reactions between specified substances (pure minerals and components of solid solutions, oxides and chemical elements) with selection of the arbitrary set of linearly independent reactions. This program may be useful for education, for analysis of diagrams (petrogenetic grids and results of multi-equilibrium geothermobarometry), for balancing of reactions involving minerals with real compositions, for evaluation of solid solution end-members, etc.
