Stock (geology)

From Wikipedia, the free encyclopedia
Smaller igneous intrusion
A stock of nordmarkite (quartz-alkalisyenite) ofTriassic age, in the Gevanim Valley, Makhtesh Ramon, southern Israel.

Ingeology, astock is anigneousintrusion that has a surface exposure of less than 100 square kilometres (40 sq mi),[1][2] differing frombatholiths only in being smaller. A stock has adiscordant relationship with the rocks that it intrudes. Many stocks arecupolas of hidden batholiths.[3][2] Some circular or elliptical stocks may bevolcanic plugs, which fill the vents of now extinct volcanoes.[4][5]Aboss is a small stock.[6]
