Hydroxide in pyroxene: Variations in the natural environment

, 1990
A suite of 51 pyroxenes from a wide range of geological environments was examined with infrared spectroscopy. Small amounts of OH occur in nearly all the samples, suggesting that OH groups are a minor component of most pyroxenes.

Hematite formed from pyroxene on Mars by meteoritic impact

, 1994
In earlier work, we showed using Mossbauer data that the mineralogy of iron-bearing phases in impact melt rocks from Manicouagan Crater (Quebec, Canada) is to a first approximation hematite and pyroxene.

Mineral dissolution in silicate melts

, 2015
Quartz and orthopyroxene in mafic rocks are commonly observed to be surrounded by fringes of granular pyroxene, and of olivine and clinopyroxene, respectively. This study reproduces the conditions of formation of these textures, and investigates their

Extent and survival of zoned pyroxene within intrusions hosting magmatic sulfides: Implications for zoned pyroxene as a prospectivity indicator

Chromium-zoning patterns in pyroxene from the economically significant Ni-Cu sulfide deposits at Nova-Bollinger (Western Australia) and Kevitsa (Northern Finland) were investigated using XRF mapping, automated mineralogy, and EPMA analyses.

Ti solubility in diopsidic pyroxene from a suite of New South Wales leucitites (Australia)

, 1989
The pyroxene chemistry from a suite of leucitites and related differentiates from New South Wales has been investigated with the aim of understanding the physico-chemical factors which may influence the Ti solubility in the pyroxene, relative to the ...
