Sites with extensive links

Claus Hedegaard - a fair number of links that include a good number of otherwise hard to find private home pages about minerals.  Also mineral localities he has visited.
Links for Mineralogists Annotated links to internet resources, especially for mineralogists, petrologists, crystallographers, and geologists divided in three categories: Knowledge, Tools and Contacts.  Maintained by Klaus-Peter Kelber, Mineralogisches Institut, Universität Würzburg, Am Hubland. D-97074 Würzburg, Germany
Mineralogy and Petrology Research on the Web -  includes links to Journals, Publishers, Topic-oriented Sites, Mineralogical Databases, Professional Societies, Laboratories, Surveys, and other Organizations, Research Groups, Mineral Collecting and Commercial, Sites, and Basic Resources.  Compiled by Andrea Koziol of Dayton (Ohio) University.
www.biogeosciences.org Biogeosciences is the study of the fundamental interactions between life and the Earth's atmosphere, hydrosphere, and geosphere, and potentially includes such life on other planets. The goal of this Web site is to bring together the biogeoscience community, advance awareness of the subject and promote the study of biogeoscience.

Mineral and Petrology Databases

Alphabetical Mineral Reference -
Athena Mineralogy -
Bayes Hompage - internally consistent thermodynamic dataset and interactive programs to generate petrological phase diagrams from the Ruhr-Universität Bochum, Germany.
Mindat.org - The largest mineral database on the internet. It was started by Jolyon Ralph in 1993 as a PC mineralogy software package for his own use - and was launched for free on the web in October 2000. Currently there are 11,125 different minerals, varieties and synonyms listed, and information on 144,323 mineral occurrences worldwide, from 26,867 different sites. What makes mindat.org different is you can take part. People all over the world are already adding their information into the database - it doesn't matter if you're an expert or not - you can help - register and add in the information on your local sites.
Mineral Database - mineral data on individual species searchable by crystallography (and a tutorial), X-ray powderdiffraction, chemical composition, physical and optical properties, Dana's New classification, Strunz classification, mineral pictures, and alphabetical listings of mineral species. By David Barthelmy.
Atlas der Krystallformen von Victor Goldschmidt (in German) The complete 9 volume Atlas der Krystallformen by Victor Goldschmidt.
QUT Mineral Database - Queensland University of Technology, Brisbane, Australia. Physical and chemical data, photos, electron microscopy images, images of thin sections and analytical data such as Mineral Vibrational Spectra in the near-, far- and mid- infrared regions of the spectrum, infrared emission spectra and Raman spectra of minerals. All the analytical data in this database were obtained in the QUT Faculty of Science laboratories.
Zeolite Database - provides structural information on all zeolite structure types. This includes crystallographic data and drawings for all zeolite framework types, simulated powder patterns for representative materials and relevant references.  By the Structure Commission of the International Zeolite Association.
LEPR, the Library of Experimental Phase Relations - an online database of experimentally determined magmatic phase relations compiled by members of Marc Hirschmann’s and Tim Groves’s research groups at the University of Minnesota and MIT and the database structure and web interface was built by Mark Ghiorso of OFM Research. LEPR contains experimental data on coexisting minerals and melts quenched from magmatic experiments, including phase compositions and, when available, proportions. LEPR also includes data pertaining to experimental techniques, such as the type of experimental device and container employed during each experiment, the duration of each experiment, and so on. Experimental conditions range from 0.1 MPa to 27 GPa and from 500 to 2550 °C. More data will be added in the future. User registration is required but access is free.
