Question

Quizplus · Accepted Answer

A stock is a small intrusive body of rock that has a similar composition and features to a batholith, but is much smaller in size, typically less than 100 square kilometers in surface exposure. Dikes and sills are also smaller bodies of intrusions, but they are primarily defined by their shape and orientation relative to the surrounding rocks (i.e. dikes are vertical or nearly-vertical intrusion that cut across preexisting rock layers, while sills are nearly-horizontal intrusions that are parallel or concordant with the bedding of the rocks they intrude). Veins are mineral deposits that fill fractures or cavities within existing rocks, and are not necessarily related to intrusive activity. Flood basalts, on the other hand, are massive outpourings of lava that cover extensive regions (up to thousands of square kilometers) and are associated with volcanic activity, not intrusive igneous activity.
