Chonolith

/ˈkɒnəlɪθ/ noun

Definition

A type of igneous rock body that has been intruded and displaced, breaking through layers of surrounding rock.

Etymology

From Greek choron (space or region) + -lith (stone). A geological term from 19th-century mineralogy for intrusive rock formations.

Kelly Says

Chonoliths are what geologists call certain igneous intrusions, and they can create valuable ore deposits when the hot magma interacts with surrounding rocks—they're basically geological bulldozers.
