NIH Image and related programs from the National Institute of Health.

http://rsb.info.nih.gov/nih-image/

NIH Image is a public domain image processing and analysis program for the Macintosh. It was developed at the Research Services Branch (RSB) of the National Institute of Mental Health (NIMH), part of the National Institutes of Health (NIH).

A free PC version of Image, called Scion Image for Windows, is available from Scion Corporation. There is also Image/J, a Java program inspired by Image that "runs anywhere".

Image can acquire, display, edit, enhance, analyze and animate images. It reads and writes TIFF, PICT, PICS and MacPaint files, providing compatibility with many other applications, including programs for scanning, processing, editing, publishing and analyzing images. It supports many standard image processing functions, including contrast enhancement, density profiling, smoothing, sharpening, edge detection, median filtering, and spatial convolution with user defined kernels.

Image can be used to measure area, mean, centroid, perimeter, etc. of user defined regions of interest. It also performs automated particle analysis and provides tools for measuring path lengths and angles. Spatial calibration is supported to provide real world area and length measurements. Density calibration can be done against radiation or optical density standards using user specified units. Results can be printed, exported to text files, or copied to the Clipboard.

More information about NIH Image can be found in the Overview section of the manual.

THERIAK-DOMINO The THERIAK-DOMINO Software collection by C. de Capitani calculates and plots thermodynamic functions, equilibrium assemblages and rock-specific equilibrium assemblage diagrams (elsewhere also called pseudo-sections). This collection includes the following programs:

Theriak, the heart of the collection, calculates the stable mineral assemblage and phase compositions for a given rock (bulk composition) at specified P,T conditions.

Domino may calculate (a) equilibrium assemblage diagrams with selectable axes (P, T, components activity and logarithms of components activity), (b) Pseudo-binary or pseudo-ternary phase diagrams, (c) Phase compositional isopleths as well as density, volume or modal amount distributions; (d) Distribution of rock bulk parameters.

Therbin and Therter calculate binary and ternary phase diagrams at constant P and/or T.

Thalia and Thermo calculate the phase or assemblage dependence of thermodynamic parameters on T or P or (binary) composition.

Guzzler and Explot are used to transform graphics information from the above programs to 'ready to use' postscript files that can be viewed on screen or printed to a hard-copy.




DRAWxtl
DRAWxtl is an open-source computer program to produce crystal-structure drawings. By Larry W. Finger, Martin Kroeker, and Brian H. Toby. Runs on Windows 2000, XP, Vista and Windows 7, Mac (OS X), Linux, other Unix-type systems, and openVMS.

Two pages with Paleomag software:
PaleoMag is an attempt to provide an integrated, graphics-oriented analysis environment for paleomagnetic data. It reads data preferably in CIT format but optionally in tab-delimited format and can display the data in orthographic (Zijderveld) plots, equal-area plots, or J/J0 plots. Users can flexibly choose data points to be fit using the line, plane, or great-circle fits described by Kirschvink (1980). Resulting fits can be displayed using equal-area or strigraphic plots and mean directions and uncertainties can be calculated using Fisher, Bingham, or non-parametric statistics. These statistics can be based either on sample fits or site averages. Several options for combining line and plane fits are allowed, and a simple reversal test is supported. Plots can be printed or copied to the clipboard but cannot be saved to disk directly.

Several Windows programs by Dmitry Dolivo-Dobrovolsky for multi-equilibrium TWQ and THERMOCALC thermobarometry

TWQ_Comb is a program 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. Only old DOS versions of the TWQ package are fully supported now. However, you can run winCMP and winTWQ programs in their batch modes for generated data files separately. You can also run DOS versions of TWQ programs under 64-bit OS (like Windows Vista, 7 and 8) due to implemented support of the DOSBox emulator.

TWQ_View is an advanced viewer of TWQ diagrams which should be used with TWQ_Comb.

TC_Comb is a wrapper for THERMOCALC running in geothermobarometry modes (AverPT + Reactions). Visualization of thermobarometry results is an important feature of the program. However, TriQuick (another program which acts as a server and editor of diagram graphics) is required for working with diagrams.

Drawpd2TVL can be used to convert THERMOCALC output files into TriQuick graphics. It is a replacement for the standard drawpd program.

TriQuick is a general purpose plotting program for creation and working with rectangular and ternary scatter diagrams and for viewing, creation and primitive editing of diagram graphics. TriQuick is also used as a server for displaying diagrams created in some of my other programs and its presence is required for their normal functioning. You can also use TriQuick for creation of animations from large series of diagram files (so that it's not necessary to use MATHEMATICA for this simple task).

All of these programs are freeware and can be found on at: http://www.dimadd.ru/en

General Description of Program Thermobarometry

The purpose of program Thermobarometry is to perform and plot the results of thermobarometry calculations. The program was written by Matthew J. Kohn at Rensselaer Polytechnic Institute (now at U. Wisconsin) and has been modified for the Macintosh by F. Spear. An attempt has been made to incorporate all reasonable calibrations of thermobarometers for crustal rocks that have been published in the literature. New code is being added frequently.

This program manual contains description of computer programs and exercises on how to run the programs. The theoretical background is discussed at length in a set of short course notes published by the American Geophysical Union and distributed at 28th I nternational Geological Congress, which was held in Washington, D.C. in July, 1989 (Spear, F.S. and Peacock, S.M. (1989) Metamorphic Pressure-Temperature-Time Paths, 102 p. American Geophysical Union, Washington.) and is also discussed in Spear, F.S. (199 3) Metamorphic Phase Equilibria and Pressure-Temperature-Time Paths, 799 p. Mineralogical Society of America, Washington, D. C.) among other places.

P-T-t programs by Ganguly

Several programs are available from Jibamitra Ganguly's ftp site for (a) Thermo-barometry, (b) Diffusion Kinetic modeling of retrograde compositional zoning in garnet and (c) high temperature thermochronology. These programs can be accessed using the following link:

http://geo.arizona.edu/~ganguly/pub/

The program files and explanations are as follows:

(a) P-T Calc: This file contains several programs for calculation of P-T conditions of rocks using garnet based thermo-barometers and the garnet solution model of Ganguly et al. (1996; CMP 126, 137-151). The programs in this file are:

  • GT-AX.EXE: Calculates activity of garnet end member components using the Ganguly et al. (1996) solution model and input data of compositions

  • GTPX-TEM.EXE: Calculates T using Grt-Opx and Grt-CPx thermometers, as discussed in Ganguly et al. (1996)

  • GtBt-GASP: There are three programs in this folder: (i) GASP1.EXE (ii) GT-BT_T1.EXE and (iii) gb-gasp1.exe.

These programs calculate (i) P using GASP barometer at a specified T, (ii) T using Grt-Bt (Fe-Mg exchange) thermometer at a specified P and (iii) simultaneously solves for both P and T using GASP and Grt-Bt equilibria. For an idea of the reliability of P-T estimates using these formulations, see Dasgupta, Ganguly, Neogi (2004, JMG 22, 395-412)

(b) DIFF-CL.ZIP: It is a ZIP file containing programs that were used to calculate average closure temperature of minerals and age profiles in individual mineral grains from input data of diffusion kinetic parameters of daughter products of radiogenic decay systems and peak temperatures. The theory was developed by Ganguly and Tirone (1999: EPSL 170, 131-140). It represents a modification of the classic Dodson (1973) formulation.

(c) REAZ_Minuit* : There are several programs in this folder for modeling retrograde compositional in garnet with homogeneous core to retrieve cooling rates (see Ganguly et al. 2000: EPSL183, 471-486)


Seismic Duck
Your task is to find and extract oil from underground anticlines, curved "hills" of sandstone. You find these anticlines by sending sound waves into the ground and recording the echos on a seismogram. The anticlines have characteristic echos that hint where to drill for oil. The difficulty increases as you play. See how far you can get before going broke! Runs on Windows and Mac. http://www.blonzonics.us/games/seismic-duck


Hornblende-plagioclase geothermometry
hbplag is a public domain application for calculating hornblende-plagioclase geothermometry for the Macintosh, DOS and Windows. It is based on the thermometers of Holland and Blundy (1994, Contrib. Mineral. Petrol., v. 116).

PHREEQC is a computer program written in the C programming language that is designed to perform a wide variety of aqueous geochemical calculations. PHREEQC is based on an ion-association aqueous model and has capabilities for (1) speciation and saturation-index calculations; (2) reaction-path and advective-transport calculations involving specified irreversible reactions, mixing of solutions, mineral and gas equilibria, surface-complexation reactions, and ion-exchange reactions; and (3) inverse modeling, which finds sets of mineral and gas mole transfers that account for composition differences between waters, within specified compositional uncertainties.

There is also a Windows version available, called PHREEQCi. Available from http://h2o.usgs.gov/software/phreeqc.html.

For a version of PHREEQC that you can run directly from your web browser, check out Web-Phreeq!


CSpace

CSpace (Composition Space) is a program aimed at facilitating the graphical and algebraic analysis of data representing compositional coordinates, such as chemical analyses of minerals, rocks or other substances or systems. CSpace focuses on techniques that are particularly suited to the needs of petrologists and mineralogists, but could also prove useful for geochemists and other environmental scientists. A few examples of what can be accomplished with CSpace are the mapping of compositions into some desired set of system/phase components, estimating reaction/mixing coefficients, assessing phase-rule compatibility relations within or between complex mineral assemblages and so on. The program also allows interactive visual inspection of composition relations by means of customizable barycentric plots that can be readily made into a variety of composition diagrams."

UnitCell: a non-linear least squares cell refinement program with regression diagnostics

UnitCell is a program which refines cell parameters from powder diffraction data. It refines cell parameters from powder diffraction data. Unlike most existing cell refinement programs it does not require initial estimates for cell constants; it uses a non-linear least squares method, which allows the refinement to be carried out on the actual observed data (e.g. two- theta in the case of angle-dispersive monochromatic diffraction, energy in the case of energy-dispersive diffraction). Furthermore, the program incorporates regression diagnostics, particularly deletion diagnostics, to aid in the detection of outliers and influential data which could be deleterious to the regressed results. These diagnostic tools are particularly valuable in assessing the sensitivity of the calculated results to the observations of individual Bragg peaks.

The method and implementation are described in the following paper:
