The Home of the Hard Rock Geologist

Here at Gabbrosoft.org we make no bones about the fact that we are mad on all things hard-rock geological. So, be you an igneous or metamorphic petrologist, a geochemist or a mineralogist, you are bound to find something here of interest!

This is also the home of our ‘World Famous’ mineral chemistry spreadsheets, which can be used to recalculate mineral stoichiometry based on electron microprobe analysis. There are also a number of other spreadsheets available that can be used to calculate a whole range of useful geochemical and geological parameters.

You can also find us on Facebook at The Hard Rock Zone which is the place to share geological news, information and images of an igneous, mineralogical, metamorphic or volcanological nature. We are also active on Pinterest, where a whole host of hard rock images are being gathered together, and our Gallery of photomicrographs and related field images is a growing resource.
