Gabbro Rock Sample - Natural Igneous Stone for Geological Study #3583284 (License: Personal Use)

This irregularly shaped rock specimen displays a phaneritic texture with interlocking crystals of dark amphibole or pyroxene and lighter-colored plagioclase feldspar. The surface shows natural cleavage planes and minor weathering, typical of intrusive igneous rocks cooled slowly beneath the Earth’s crust. Its dense, heavy appearance suggests a mafic composition rich in iron and magnesium.

Used in educational geology websites, museum digital collections, and mineral identification guides; serves users seeking visual reference for igneous rock classification, especially for distinguishing gabbro from similar rocks like diorite or basalt.
