An accurate description of the effect extreme pressure and temperature on physical properties materials is required to understand structure composition mantle Earth similar planets. One such enstatite MgSiO 3 , which causes increased interest in investigating its behavior under intense dynamic loads.

Liquidus phase relationships determined on the join CaAIzSi20 8 (anorthi te)-MgzSiO 4 (forsteri te)-SiO 2 (quartz) at 10 kbar show that increasing pressure causes the forsterite and anorthite primary phase fields to shrink and the spinel, enstatite and silica fields to expand. The boundary line between the enstatite and forsterite fields and that between the enstatite and quartz fields both mov...

Enstatite achondrites (including aubrites) are the only differentiated meteorites that have similar isotope compositions to Earth-Moon system for most of elements. However, origin and differentiation enstatite their parent bodies remain poorly understood. Here, we report high-precision mass-independent mass-dependent Cr data 10 achondrites, including eight aubrites, Itqiy one enstatite-rich cla...

This study reports the bulk rare earth element (REEs, La–Lu) compositions of 41 chondrites, including 32 falls and 9 finds from carbonaceous (CI, CM, CO and CV), enstatite (EH and EL) and ordinary (H, L and LL) groups, as well as 2 enstatite achondrites (aubrite). The measurements were done in dynamic mode using multi-collector inductively coupled plasma mass spectrometers (MC-ICPMS), allowing ...

Calcium^aluminum-rich inclusions (CAIs) from enstatite chondrites have large 16O excesses, similar to CAIs in carbonaceous and ordinary chondrites, and are also similar in morphology, mineralogy and Al^Mg isotopic systematics. These similarities provide new evidence that most CAIs might have formed in a single, restricted nebular locale and were then distributed unevenly throughout the various ...
