نرم افزار HB-PLAG

نام انگلیسی: 
HB-PLAG
درباره ی نرم افزار: 

HB-PLAG is program to calculate temperatures from chemical analyses of coexisting hornblende and plagioclase (usually determined by electron microprobe).‎ The method is fully documented in Holland & Blundy ‪(1994 Cont.‎ Min.‎ Pet.‎ 116, 443-447)‬.‎

نرم افزار Thermo- Calc

نام انگلیسی: 
نرم افزار Thermo- Calc
درباره ی نرم افزار: 

THERMOCALC is a thermodynamic calculation software package for tackling mineral equilibria problems.‎ It has two main components: the application itself, and the internally-consistent thermodynamic dataset it uses.‎

نرم افزار AX

نام انگلیسی: 
AX
درباره ی نرم افزار: 

AX is a program which takes mineral analyses in the form of either oxide weight percent or as cations per formula unit and calculates the activities of the mineral endmembers useful for thermodynamic computations.‎ Errors are propagated from the probe data to the final activities.‎ This program is designed for users wanting approximate activities to use for thermo-barometric calculations, and does not use very sophisticated models ‪(output for each mineral phase lists the assumptions made in each calculation)‬.‎

نرم افزار CHO

نام انگلیسی: 
CHO
درباره ی نرم افزار: 

CHO is a program which allows the user to derive molar volumes, fugacities and activities for H2O, CO2, CH4, H2 and CO and perform speciation calculations at fixed P, T and fO2 in the O-H and C-O-H systems.‎ It uses the CORK equation of state (Holland & Powell 1991, CMP 109, 265-273) for all COH gases and additionally allows use of the Pitzer & Sterner equations (Pitzer & Sterner 1995, Int J Thermophys 16, 511-518) for H2O and CO2.‎ For gas mixtures the program uses the Van Laar mixing model as outlined in Holland & Powell (2003, CMP 145, 492-501) but also allows this to be overridden in favour of ideal mixing.‎

نرم افزار UnitCel

نام انگلیسی: 
UnitCel
درباره ی نرم افزار: 

UnitCell is a program which runs on Macintosh computers and under Windows.‎ 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.‎

نرم افزار Geoplot

نام انگلیسی: 
Geoplot
درباره ی نرم افزار: 

GeoPlot is a free VBA macro program used in Excel for plotting geochemical data.‎ It has the following functions: X-Y plot, triangular plot, normalized spidergram, discrimination diagram, and the related functions such as calculating formulas and CIPW norm.‎ GeoPlot also contains many normalization values used for spidergram and many discrimination diagrams.‎ Users can also add new normalization values for spider diagrams and the specification data for a new discrimination diagram into GeoPlot.‎ This program provides a menu and a toolbar in Excel for allowing easy management of these functions.‎ GeoPlot has the advantage over the existing stand-alone plotting programs in that it allows data to be plotted and visualized easily in the Excel environment, which geochemists use to organize and valuate the data.‎ 

نرم افزار Petroplot

نام انگلیسی: 
Petroplot
درباره ی نرم افزار: 

Interpretation of geochemical data requires visualization of increasingly large data sets in multiple dimensions.‎ Data are commonly archived in spreadsheet format, and therefore efficient visualization tools within this environment are necessary.‎ PetroPlot is a 4000-line software code written in Visual Basic for the spreadsheet program Excel that automates petrologic plotting and data management tasks for large amount of data.‎ The major plotting functions include: automation of large numbers of multi-series XY plots or spider diagrams;‎ re-plotting of any complex formatted diagram with multiple series for any other axis parameters;‎ and addition and removal of customized labels for individual data points.‎ Other functions include: assignment of groups for samples based on multiple customized criteria;‎ removal of non-numeric values;‎ calculation of averages/standard deviations;‎ calculation of correlation matrices;‎ deletion of non-consecutive rows;‎ and compilation of multiple rows of data for a single sample to single rows appropriate for plotting.‎ For users of Excel, PetroPlot increases efficiency of data manipulation and visualization by orders of magnitude, and allows exploration of large data sets that would not be possible making plots individually.‎ The source codes are open to all users.‎

SolvCalc 2.‎0

نام نرم افزار: 
SolvCalc 2.‎0
درباره ی نرم افزار: 

Please check http:\\sbmp96.ess.sunysb.edu\SolvCalc for more recent help document.‎

 The program SOLVCALC 2.‎0 is a user-friendly graphic interface software for calculating the ternary feldspar solvus and the equilibrium temperature of coexisting natural ternary feldspar pairs.‎ Six different thermodynamic models for ternary feldspar are incorporated into this program for both solvus calculations and thermometry.‎ An activity matching algorithm is used for the solvus calculations.‎ For the geothermometric calculations, an algorithm is used to search for the most concordant temperature by adjusting the feldspar compositions within chosen uncertainty.‎ SOLVCALC 2.‎0 can be used as both a research and teaching tool for comparing different models as well as for development of new ternary feldspar models.‎ It includes one user-defined model and the models of Elkins and Ghiorso (1984)‎, Green and Usdansky (1986)‎, Grove (1990)‎, Fuhrman and Lindsley (1988)‎, Lindsley and Nekvasil (1988)‎, Nekvasil and Burnham (1987)‎, for calculating ternary feldspar equilibria.‎ The calculation of SOLVCALC 2.‎0 can be conceptually divided into two main functions: SolvusCalc and ThermoCalc.‎ SolvusCalc calculates isothermal sections of the ternary feldspar solvus using any or all of the seven models (including the user-defined model) and plots the isotherms in the ternary feldspar system Ab-Or-An.‎ Given a pressure and a two-feldspar compositional pair, ThermoCalc searches for the closest matching tieline and the equilibrium temperature by adjusting the compositions within an uncertainty defined by the user.‎ This search may be conducted within an entire range of uncertainty or the user may fix one or more compositional values of the end members, thereby limiting the search range.‎ The tielines and uncertainty circles are then plotted in the ternary feldspar system Ab-Or-An.‎

The program runs on PC compatible computers with Windows 95 or NT.‎ A copy of SOLVCALC 2.‎0 is available from ftp//sbmp04.ess.sunysb.edu/solvcalc2.zip.‎
