troctolite [′träk·tə‚līt]

(petrology)

A gabbro composed principally of calcic plagioclase and olivine. Also known as forellenstein.

Troctolite

an igneous rock of the gabbro group, consisting mainly of basic plagioclase (labradorite or bytownite) and small amounts of olivine. Pyroxenes are either present in negligible amounts or completely absent. Serpentinization of the olivine is sometimes accompanied by the formation of characteristic fissures, which radiate from the olivine grains, in the plagioclase.
