A global encyclopedia of ore deposits

Data Metallogenica is described as a 'global encyclopedia of ore deposits,' that includes a database which contains:

• Samples from nearly 4,000 mineral deposits from more than 70 countries
• Photographs of 70,000 representative rock samples world-wide
• Descriptions, maps, cross-sections, field & mine photographs
• Spectral mineralogy of altered rocks
• Complete research theses on mineral deposits
• A database listing of 10,000 Australian geoscience theses
• Searching by text or map  

The DM center is based in Adelaide Australia but is global in its coverage.  DM was set up as a self-funding not-for-profit enterprise. DM says its "internet database is now on-line and available to anyone wishing to subscribe. The rate is a sliding scale to make it affordable both for individuals and for organisations of different sizes. A special rate has been struck for universities and geological surveys, with significant discounts available to companies and institutions that sponsor DM."

There is a free search tool that provides limited access to the online resources.
