This site is devoted to microscopic images of minerals, thin sections of rocks and meteorites, and stereoscopy of minerals. The site is organized into the following categories: meteorites, plutonic rocks, volcanic rocks, carbonates, sedimentary rocks, sedimentary rocks and diatoms. Other links include conoscopic images, an index measurement page containing theoretical information about index of refraction ... Full description.

This web site includes almost 200 photomicrographs of rocks and minerals. The thin sections are all in transmitted white light, some in plane polarized light, but most with crossed polarizers on. The majority of the pictures show a field of view 1.5 mm long (about 80X magnification). Other magnifications are indicated where different. The thin sections are categorized into minerals, igneous, metamorphic, ... Full description.

This is a collection of photomicrographs of igneous rocks. There are 69 photomicrographs with captions containing pertinent information. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html Full description.

This page is a collection of photomicrographs of metamorphic rocks. There are 45 photomicrographs with captions containing pertinent information. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html Full description.

This site contains photographs of 22 igneous rock hand samples. Clicking on an image brings up a larger view of the sample. In addition, links to thin sections are available for some of the samples. Thin sections can be seen in both crossed polarized light and plane polarized light by moving the cursor on and off the photomicrograph.

This site contains photographs of 18 metamorphic rock hand samples. Clicking on an image brings up a larger view of each sample. Images of thin sections are available for some of the samples. Thin sections can be seen in both crossed polarized light and plane polarized light by moving the cursor on and off the photomicrograph.

This website, designed for a Sediments and Strata course at the University of California- Davis, contains numerous photographs of turbidite sequences in outcrop. Photos are divided into two categories; turbidites in the Cretaceous Pigeon Point Formation and turbidites in the Cretaceous Great Valley Sequence. Users may also follow a link to other sedimentary photos. Full description.

This PowerPoint presentation is part of the Whitman College petrology course. The presentation explains how igneous textures form and provides many pictures of igneous textures in microscope view.

This 24-slide PowerPoint presentation describes the classification of metamorphic rocks using texture and composition. Foliation, lineation, cleavage, schistosity, gneissose structure, hornfels, and granofels are discussed. Specific metamorphic rock types and modifying terms (porphyroblastic, spotted, augen, para-, ortho-) are defined and photographs of some are provided. This resource is part of ... Full description.

This PowerPoint presentation covers metamorphic textures such as relict, deformation, recrystallization, and recovery. Contact metamorphic textures are discussed, including decussate, granoblastic and polygonal. Photographs of metamorphic rock textures are provided.
