This image gallery provides pictures of thousands of mineral specimens, arranged alphabetically. For each specimen, a thumbnail and a larger image are provided. Other information includes a brief description of the specimen being shown, scale bar (when available), locality data, and a link to additional information on the mineral. Full description.

This directory provides a listing of minerals arranged by Powder X-ray Diffraction (XRD) data . XRD is one of the primary techniques used to examine the physico-chemical make-up of unknown solids, in which a powdered sample is illuminated with X rays of a fixed wavelength and the intensity of the reflected radiation is recorded using a goniometer. Minerals are arranged in increasing order of D1 spacing, ... Full description.

This web page provides an interactive petrological database of the ocean floor. The ultimate goal is to provide a robust, complete reference data library for the petrology and whole earth science communities. Users enter search parameters such as geographical name, latitude, longitude, elevation, tectonic setting, expedition name and chemistry, and receive information on the petrological condition ... Full description.

This is a large database of minerals that can be sorted either alphabetically or arranged systematically. Users can access minerals by name, elements, sulfides, halides, oxides, carbonates, sulfates, phosphates, silicates, organic minerals, or by variety. Once located, the properties of the mineral are displayed, including its chemical formula, crystal system, and location. Users can also access photos ... Full description.

This undergraduate course deals with principles and concepts fundamental to understanding the physical, chemical, crystallographic and structural properties of minerals. There is a syllabus, annotated lecture schedule, list of lecture topics with assoicated links, and a set of on-line quizzes for student self assessment. Full description.

This directory provides a listing of mineral species based on Dana's New Mineralogy, in which a number is assigned to each class based on a combination of chemistry and crystal structure. Clicking on each class heading provides access to a list of each mineral that conforms to that class. Each mineral name is a link to additional information on the mineral. Full description.

This directory provides a listing of mineral species under the Strunz system, a chemical-structural system for classifying minerals. Clicking on each class (elements, sulfides, oxides/hydroxides, etc.) provides a listing of all minerals that conform to that class. Each mineral name is a link aditional information on the mineral. Full description.

This is a listing of mineral species arranged by physical and optical properties: hardness, streak, and luster; density; cleavage and fracture; refractive index; or color. Clicking on each property provides access to a list of minerals exhibiting that property; clicking on each mineral name provides access to more detailed information about it. Full description.

This directory provides an alphabetical listing of more than 4,000 mineral species. Clicking on each mineral name provides access to information including chemical formula and composition, locality and name origin, physical properties, optical properties, images, and many others. Full description.

This table summarizes the 32 crystal classes by crystal system and class name, including symmetry elements. Clicking on each system or class heading provides information on each class within the system, including axes of rotation, symmetry planes, center, and Hermann-Maugin symbols. There is also an illustration, paper models that can be downloaded, printed and assembled, animated pop-ups that show ... Full description.
