These lecture notes introduce magmatism and petrology as they relate to the oceanic lithosphere. The notes cover ophiolite sequences and types of volcanic settings found in ocean basins. A section about basalt includes discussion of location, composition and origin of mid-ocean ridge basalts. Ocean island basalts are further discussed with regards to occurrence, composition and origin. These notes ... Full description.

These lecture notes discuss metamorphic textures and the mechanisms that create them. A discussion of foliation covers types of stress and the development of foliated rocks from slate to gneiss. Five modes of metamorphic differentiation are introduced including preservation of original compositional layering, transposition of original bedding, solution and re-precipitation, preferential nucleation, ...

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.
