Density of gabbro

WebDiabase ( / ˈdaɪ.əˌbeɪs / ), also called dolerite ( / ˈdɒl.əˌraɪt /) or microgabbro, [1] is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite ... WebAug 23, 2024 · Gabbro is a coarse-grained rock composed of the minerals pyroxene, plagioclase, and small amounts of olivine and amphibole. Black granite has lower density quartz content and a higher proportion of dark minerals with ions and other metals; therefore, it is much denser than other igneous rock types.
