In British English: /ˈpʌɪrəkˌsiːn/ (PYE-ruh-keen). In American English: /paɪˈrɑːkˌsiːn/ (pye-ROCK-seen).
Both are silicate mineral groups, but they differ in crystal structure and cleavage angles. Pyroxenes have nearly 90-degree cleavage, while amphiboles have about 120/60-degree cleavage.
Yes. Pyroxenes are common in basalt, gabbro, and some metamorphic rocks. They are a major component of the Earth's mantle and are also found on the Moon and Mars.
