X-ray diffraction study of enstatite 12 GPa 1473 K equations of state
2012/4/1
Crystal structures and phase transitions of enstatite (MgSiO ) were studied by in situ X-ray dif-fraction experiments using synchrotron radiation and a multi-anvil high-pressure apparatus at pres-/c t...

Experimental determination Magnesite + enstatite = forsterite + CO2
2012/3/31
he P - T equilibrium curve of the reaction of magnesite 1 enstatite 5 forsterite and CO2 was determined in the ranges 6?5 kbar and 700?100 8 C by 53 reversed experiments carried out in 1.91 cm diamete...
The reaction talc + forsterite = enstatite + H2O: New experimental results and petrological implications
reaction talc H2O New experimental results
2012/3/30
The reaction talc 1 forsterite 5 enstatite 1 H2O has been investigated between 6 and 20 kbar. Previous high-pressure experimental studies suggested various reaction positions,mostly with positive P - ...

The reaction of phlogopite plus quartz to enstatite, potassium feldspar, and aqueous fluid in the system KMASH-KCl was reversed at 2?2 kbar and 750?75 8C and at low H2O activities by reversal of the H...
Weathering of Enstatite to Talc Through a Sequence of Transitional Phases
Biopyribole Enstatite Smectite Talc Transmission electron microscopy Weathering
2011/11/23
Abstract: Orthopyroxene (En85) weathers initially by vacancy diffusion, and through this process hydration occurs and a sequence of biopyriboles develops, culminating in a talc-like layer silicate who...
