Downloadable programs by Ken Wohletz
at Los Alamos National Labs include:
Erupt which generates
2D animations of compound eruptions
Heat which models 2D
heterogeneous heat dissipation
Magma which calculates
viscosity and density for magma compositions, in addition to classifying the
magma type
The Soft Earth
is a good site for seeing what is available "out there" on the WWWeb.
NewPet
Software is another good site and includes programs for rose diagrams and
ternary plots.
This is a
temporary addition primarily to download programs from
This site
is yet to be located but is on this page as a hopeful item brought to us by
Roger Powell and Brenton Worley at University of
Melbourne
Earth
Science Resources are a link to the University of Calgary which some of the
same sites as the others.
"IGNEOUS"
which is a magma modelling type
program by Todd Dunn.
"MINCALC2"
which is a program (again by Todd Dunn) for
converting mineral analyses to cation proportions.
This GeoKem link brings you to a page full of geochemical data and plots – offering examples of different magma compositions from all over.
This link leads you to the GERM site (Geochemical Earth Reference Model) – including a site for Partition Coefficient data for just about any element into any phase.
A WWWebsite browser flowchart which will walk you through
how to identify and classify igneous rocks
A tutorial concerned with Petrology and Plate Tectonics -
put out by the good folks at
A tutorial treating the Earth's interior and Plate Tectonics
Ternary
diagrams tutorial for understanding ternary plots
the IUGS
classification scheme for identifying and classifying igneous rocks
Tutorials and lecture notes from other Petrology and Geochemistry courses are
also available; for instance these concerning: the Rb-Sr
isotope system or the the Sm-Nd isotope system or
the the stable isotopes
Chemical data may also be obtained from the WWWeb.
The
interactive Periodic Table at this site (Los Alamos National Lab) is one of
the best available on the WWWeb, as is this Periodic Table maintained by
the Illinois State Geological Survey. There are many others - in all languages
- and with slightly different emphases. A word of caution: some contain
erroneous information - so - BEWARE.
