Metamorphic evolution of sillimanite gneiss in the high-pressure terrane of the Western Gneiss Region (Norway) [PDF]
European Journal of MineralogySillimanite-bearing gneisses in the Romsdal region of the Western Gneiss Region (south Norway) have been investigated to document the presence, formation, composition and petrological evolution of the sillimanite-bearing assemblages. Sillimanite is found

Geochemistry, Geophysics, GeosystemsThe formation, storage, and evolution of granitic magmas are fundamental processes driving the growth of continental crust. While traditionally attributed to crystal fractionation in high‐melt fraction magma chambers, the model invoking low‐melt fraction

Aspects of Infrared Radioluminescence dosimetry in K-feldspar
Geochronometria, 2013 Infrared radioluminescence (IRRL) of K-feldspar, detected at peak wavelength of 865 nm, is emerging as a potential geochronometric tool. The present study explores and attempts to optimize the IRRL dating protocols and proposes a revised protocol for estimation of palaeodose.

The Quartz-feldspar-lithic (QFL), and feldspar composition data in the sediments can provide valuable information on the provenance and the weathering intensity of the sediments. Traditionally, the QFL composition is identified under binocular microscope.

Comparing the accuracy and precision of luminescence ages for partially-bleached sediments using single grains of K-feldspar and quartz [PDF]
, 2019 Glacial settings are considered to be the most challenging context for the application of luminescence dating. The optically stimulated luminescence (OSL) signal of quartz is often preferred for luminescence dating in partially-bleached settings as it ...

Colloids and InterfacesFine spodumene particles are challenging to treat by froth flotation and are often discarded. An approach to recover the lithium-bearing mineral is to selectively aggregate fine spodumene into larger sizes that are amenable to recovery by flotation. This
