Petrology: Igneous textures – Kurt Hollocher

This shows a quartz-rich xenolith enclosed in a granitic porphyry. At the time the xenolith became trapped, the magma was undersaturated with respect to quartz. The quartz reacted with the magma to grow a rim of hornblende. Later, the magma became quartz-saturated and grew quartz and hornblende as distinct, separated crystals.

Basalt

Basalt A basalt is a fine-grained basic igneous rock containing essential calcic plagioclase feldspar and pyroxene (usually Augite), with or without olivine. Basalts can also contain quartz, hornblende, biotite, hypersthene (an orthopyroxene) and feldspathoids. Basalts are often porphyritic and can contain mantle xenoliths.
