Eucrite - Wikipedia
Eucrites are achondritic stony meteorites, many of which originate from the surface of the asteroid 4 Vesta and are part of the HED meteorite clan. They are the most common achondrite group with over 100 meteorites found. Eucrites consist of basaltic rock from the crust of 4 Vesta or a similar parent body.
Eucrite | Meteorite, Igneous Rock, Basalt | Britannica
Eucrite, rock that contains 30 to 35 percent calcium-rich plagioclase feldspar (bytownite or anorthite), as well as augite, hypersthene, pigeonite, and olivine. The name was given (1863) by Gustav Rose to stony meteorites of this composition (see achondrite), but it …
Eucrite - an overview | ScienceDirect Topics
Eucrite is a type of rock found in Earth and Planetary Sciences that typically consists of major orthopyroxene or pigeonite, calcic plagioclase, and minor to accessory minerals like silica, chromite, and phosphate.
The origin of eucrites, diogenites, and olivine diogenites: …
Jul 8, 2013 · Rarer rock types include cumulate eucrites and olivine-bearing diogenites. This large and diverse suite of meteorites provides a detailed picture of Vesta's igneous and postigneous history.
Eucrite‐type achondrites: Petrology and oxygen isotope …
Oct 4, 2021 · We report petrologic studies and oxygen isotope analyses of normal and anomalous eucrites, termed eucrite-type achondrites. Petrologically anomalous eucrite-type achondrites can have normal oxygen isotope compositions, and vice versa.
Eucrites - Meteorite Museum
Classification: Eucrite (diabasic, unbrecciated). Specimens: 43 g including two polished thin sections at UWB; 51.7 kg (including a 35.9 kg mass) with DPitt and the remainder with anonymous collectors. This is 1 of 273 approved meteorites classified as Eucrite-mmict.
The Crystallization Age of Eucrite Zircon | Science - AAAS
Eucrites are a group of meteorites that represent the first planetary igneous activity following metal-silicate differentiation on an early planetesimal, similar to Asteroid 4 Vesta, and, thus, help date geophysical processes occurring on such bodies in the early solar system.
Eucrite meteorite: Mineral information, data and localities.
Eucrites are the most abundant type of basaltic achondrite, linked by geochemical traits such as oxygen isotopic ratios and certain elemental ratios, of which Fe/Mn is the most widely cited. The main minerals in eucrites are Fe-rich pyroxene and Na-poor plagioclase.
Eucrite meteorites - SpringerLink
Eucrites are igneous meteorites that are characterized by subequal proportions of low-calcium pyroxene (pigeonite) and anorthitic plagioclase.
Eucrite Definition & Meaning - Merriam-Webster
