What Does OP Stand For?

OP stands for Oceanic Plagiogranites

Oceanic Plagiogranites (OP) refer to a specific type of intrusive igneous rock found primarily in oceanic crustal settings. Characterized by a mineral composition that predominantly includes plagioclase feldspar and quartz, these plutonic rocks typically form during the partial melting of basaltic mantle rocks in tectonic environments such as mid-ocean ridges and subduction zones. Their study provides valuable insights into the geology and evolution of oceanic lithosphere, as well as the processes involved in sea-floor spreading and mantle dynamics.
