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 ...

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

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

MINERAL CHEMISTRY OF FELSIC EXTRUSIVE ROCKS OF THE EAST BAYMAK AREA OF THE SOUTHERN URALS AND APROBLEM OF HYBRIDISM IN THEIR GENESIS [PDF]
Минералогия, 2018 The Baymak ore district hosts numerous small Au-rich massive sulfide polymetallic deposits, which is a distinctive feature in comparison with other regions of the West-Magnitogorsk zone (Seravkin, 1986). According to geophysical data, the Baymak block is

Emergent 1/3 magnetization plateaus in pyroxene CoGeO_{3}
Physical Review Research, 2021 Despite the absence of an apparent triangular pattern in the crystal structure, we observe unusually well-pronounced 1/3 magnetization plateaus in the quasi-one-dimensional Ising spin chain compound CoGeO_{3} which belongs to the class of pyroxene ...
