Stock (geology)

A stock of nordmarkite (quartz-alkali syenite) of Triassic age, in the Gevanim Valley, Makhtesh Ramon, southern Israel.

In geology, a stock is a discordant igneous intrusion having a surface exposure of less than 40 sq mi (100 km2), differing from batholiths only in being smaller.[1][2] Most stocks are probably the cupolas of hidden batholiths. Circular or elliptical stocks may have been vents feeding former volcanoes.
