Basalt - an overview ScienceDirect Topics

Basalt is the most widely distributed basic extrusive rock, with a SiO 2 content ranging from 45% to 52%, and is mainly composed of basic plagioclase and monoclase pyroxene, followed by orthopyroxene, peridot and amphibole. Pyroxene in basalt often has a complete crystalline, short columnar structure; plagioclase in basalt has a fine needle-like nondirectional arrangement.
