Despite the on-going Ebola crisis AMR Gold has recommenced its exploration and evaluation programmes on its three Loko Hills Exploration Licences for gold, tin, coltan and accessory minerals
Contract notice: Purchase of two mass spectrometers for basic research of stable isotopes and accessory minerals
necessary for their effective functioning.
In this paper, accessory minerals
such as zircon, sphene and apatite are studied in Ghareh Gheshlagh area.
Zircon, opaque minerals, titanite and Fe oxides are present in the rock as accessory minerals
Rare earth elements in ultramafic and mafic rocks and their minerals; minor and accessory minerals
The groundmass is composed of quartz, feldspar, devitrified glass, minor magnetite, ilmenite, pyrite, rare galena, fluorite and accessory minerals
similar to those in trachyte samples (i.
We suggest that the reason for this lies in the physical effect of hydraulic sorting on coarser REE-bearing accessory minerals
which have been left behind during fluvial transport of these river gravels.
The use of epigenetic interlayer solution of some accessory minerals
for establishing the time of formation of oil deposits // Epigenesis and its mineral indicators / A.
He-diffusion studies have also been conducted for other common minerals such as titanite, monazite, hematite, and zircon, all of which are common accessory minerals
in igneous and metamorphic rocks.
This specific deposit contains 70 per cent calcite, a form of calcium carbonate; 10 per cent apatite, a rock phosphate (source of calcium and phosphorous); 15 per cent biotite/vermiculite; and 5 per cent of accessory minerals
such as pyroxene, chlorite, magnetite, and feldspar.
The three papers in the first section focus on petrological observations combined with trace element and isotopic data of accessory minerals
to link their formation with major mineral phases, and ultimately to the pressure-temperature-time path of metamorphic rocks.
Apatite, zircon, and rutile are typical accessory minerals
