Investigating the relative adsorption of polymeric depressants on pure minerals [PDF]
, 2011 The aim of this study was to investigate the relative adsorption of polymeric depressants on pure minerals. The minerals used were talc, pyroxene, plagioclase, chromite and chalcopyrite and the depressants used were guar gum and carboxymethyl cellulose ...

Newly found rock-forming minerals in the eastern part of the Slovak Ore Mountains, Western Carpathians, Slovakia [PDF]
Acta Montanistica Slovaca, 1996 This work focuses on first occurrences of more than 20 silicate minerals in the study area. In addition to amphiboles group (six minerals), pyroxenes (three minerals), different varieties of garnets and schist silicates and some Mn-rich minerals are ...

A critical evaluation of two-pyroxene thermometry in Adirondack granulites [PDF]
, 1979 Temperatures have been calculated from the composition of sixty-five coexisting ortho- and clinopyroxene pairs from the Adirondacks, New York, using calibrations proposed by Wood & Banno (1973), Ross & Huebner (1975), Saxena (1976) and Wells ...

PETROGRAPHY AND MICROTEXTURAL CHARACTERISTICS OF GRANODIORITE FROM WASIMI, SOUTHWESTERN NIGERIA [PDF]
Earth Science Malaysia, 2020 Rock samples of granodiorite from Wasimi were studied in detail to determine the minerals, mineral associations and the different micro-texture present in order to unravel the processes that were involved during the cooling of the magma.

Magnetic Anisotropy in Single Crystals: A Review
Geosciences, 2018 Empirical relationships between magnetic fabrics and deformation have long served as a fast and efficient way to interpret rock textures. Understanding the single crystal magnetic properties of all minerals that contribute to the magnetic anisotropy of a

Pyroxene mineralogies of near-Earth vestoids.
, 2009 We have calculated pyroxene mineralogies of seven near-Earth asteroids (NEAs) with reflectance spectra similar to HEDs (howardites, eucrites, and diogenites). Two different sets of formulas (Gaffey et al. 2002; Burbine et al.

Cosmogenic 3He exposure dating in mafic rocks by “Virtual mineral separation” of pyroxene [PDF]
GeochronologyWe describe a “virtual mineral separation” method for measuring the cosmogenic 3He concentration in pyroxene in mafic rocks that consist mainly of plagioclase and pyroxene, without physically separating the minerals. This approach is significantly faster

Yamato-8451: A newly identified pyroxene-bearing pallasite [PDF]
, 1995 P(論文)Yamato-8451 is an unusual meteorite which is newly identified as a pyroxene-bearing pallasite. It consists mainly of Fe-Ni metal, olivine and pyroxene, and shows a porphyritic texture typical of most olivine, the same texture as that of all known ...
