In geology, a stock is an igneous intrusion that has a surface exposure of less than 100 square kilometres (40 sq mi),[1][2] differing from batholiths only in being smaller. A stock has a discordant relationship with the rocks that it intrudes. Many stocks are cupolas of hidden batholiths.[3][2] Some circular or elliptical stocks may be volcanic plugs, which fill the vents of now extinct volcanoes.[4][5] A boss is a small stock.[6]
