Lherzolite - Wikipedia
网页Lherzolite is a type of ultramafic igneous rock. It is a coarse-grained rock consisting of 40 to 90% olivine along with significant orthopyroxene and lesser amounts of calcic chromium -rich clinopyroxene. Minor minerals include chromium and aluminium spinels and garnets.
Lherzolite Rock Composition and Occurrence - Geology Base
网页2023年12月18日 · Lherzolite is a dense, coarse-grained, dark greenish to greenish-black rock. It may be massive or layered, and alteration may change its colors. On a hand specimen, this rock will have dark green forsterite olivine (iron-rich olivine) and enstatite (orthopyroxene).
Lherzolite - an overview | ScienceDirect Topics
网页Lherzolite refers to the structurally oldest rock type, characterized by spinel-peridotite facies equilibrium assemblages and clinopyroxene-rich compositions, that has been uplifted and equilibrated in the lithosphere under specific pressure and temperature conditions.
Peridotite - Wikipedia
网页Peridotite (US: / ˈpɛrɪdoʊˌtaɪt, pəˈrɪdə -/ PERR-ih-doh-tyte, pə-RID-ə-) is a dense, coarse-grained igneous rock consisting mostly of the silicate minerals olivine and pyroxene. Peridotite is ultramafic, as the rock contains less than 45% silica.
Lherzolite - SpringerLink
网页Lherzolite is an ultramafic rock first identified at the Etang du Lherz in the Pyrenees in 1797, and first described from this and other Pyrenean localities by Lacroix (1894). The original rock consists of olivine, two pyroxenes—a calcic clinopyroxene and a magnesian orthopyroxene—and accessory spinel.

A two-pyroxene- and olivine-bearing, coarse-grained, ultrabasic rock consisting of essential magnesium-rich olivine, chromium-magnesium clinopyroxene (Cr-diopside), magnesium orthopyroxene (enstatite), and garnet or spinel, which is found as xenoliths in basalts and as a component of Alpine ultramafic bodies.
