WebThe crust of Earth is of two distinct types: Oceanic: 5 km (3 mi) to 10 km (6 mi) thick [4] and composed primarily of denser, more mafic rocks, such as basalt, diabase, and gabbro. Continental: 30 km (20 mi) to 50 km (30 mi) thick and mostly composed of less dense, more felsic rocks, such as granite. WebDec 27, 2024 · Iron and magnesium each make up just under 5% of the crust’s mass, but they combine with SiO 2 and other elements to form pyroxenes and amphiboles. These two important mineral groups constitute around 16% of crustal rocks. Maybe the best known of these minerals are the two varieties of jade, jadeite (pyroxene) and nephrite (amphibole). dewalt battery pack 18v
