Reservoir induced seismicity provides a suitable method for studying the roles of fluid in inducing earthquakes. The fault structure plays a predominant role in the occurrences of earthquakes, and the influences of fluid also cannot be disregarded. In this study, we investigate the active Fairy Mount fault in the Three Gorges Reservoir. Since water impoundment in 2003, more than 4000 detectable earthquakes have occurred along the fault. The vast majority of these earthquakes are associated with ...

One of the best-preserved dykes of olivine minette among the lamprophyre dyke swarm in the Moldanubian Zone of the Bohemian Massif (Czech Republic) was investigated. The minette, exposed at Horni Kožli Village (near Prachatice town), has porphyric texture with phenocrysts of olivine, clinopyroxene, orthopyroxene and biotite in a fine-grained matrix consisting of K-feldspar, biotite, clinopyroxene and minor plagioclase and quartz. Accessory minerals are apatite, Cr-rich spinel and iron sulphides....

Reaction rim growth experiments provide insight into mass transport phenomena, which are important for metamorphic rock-forming processes and deformation mechanisms. We investigated the formation of enstatite single rims between quartz and forsterite and of enstatite-forsterite double rims between quartz and periclase using porous polycrystalline starting materials. About 3 wt% water was added, acting as a catalyst for reactions. Experiments of mainly 4 and 23 h duration were performed in a Pate...

Controlling the consistency of aluminium ore concentrate is difficult when there is no proper sampling protocol in place. A proper sampling strategy is necessary to obtain the data for effective quality assurance and quality control. Inputs from several disciplines, including statistics, geostatistics, geology, and sampling, are necessary to establish realistic goals for assessing the accuracy and precision levels regarding the main constituents of aluminum ore, namely available alumina and reac...

Orthocuproplatinum, Pt3Cu, is a new mineral from the Lubero region of North Kivu, Democratic Republic of the Congo. The mineral, which has a synthetic analogue, occurs as a 1.5-mm-long alluvial grain in a heavy-mineral concentrate, together with the holotype specimen of kitagohaite, Pt7Cu. The grain of orthocuproplatinum has a rim of hongshiite, PtCu, and abundant inclusions of calcite. Opaque and metallic, orthocuproplatinum has a whitish colour in reflected light and slightly perceptible aniso...

Mechanochemical activation can be defined as a process able to induce structural disorder through intensive grinding. In certain conditions, it may increase the chemical reactivity of the processed material. The process is extensively utilized in extractive metallurgy, synthesis of nanocomposites or pharmacology. It is also considered an environmentally friendly alternative to activate kaolinitic clay avoiding high calcination temperature. This paper aims to give a comprehensive overview of the ...

The structure of trigonal ferrinatrite, Na3Fe(SO4)3⋅3H2O, from the Hongshan Cu-Au deposit, Eastern Tianshan, NW China was refined in space group P\( \overline{3} \) based on single crystal X-ray diffraction data [a = 15 .553(2), c = 8.6616(17 ) A, V = 1814.4(5) A3, Z = 6; R1 = 0.0535]. All hydrogen atoms were located by difference Fourier methods and refined with soft restrictions for distances, but with fixed thermal isotropic displacement parameters. The atomic arrangement in ferrinatrite is b...

Unusual agpaitic syenites containing up to 25 vol.% lamprophyllite-group minerals (lamprophyllite, fluorlamprophyllite, barytolamprophyllite, and the new mineral species fluorbarytolamprophyllite, IMA 2016–089) have been discovered in the Niva intrusion and Mokhnatye Roga alkaline dyke belonging to the Kola Alkaline Province, northwestern Russia. The other main components of the rocks are potassium feldspar, Ti-rich aegirine-augite, aenigmatite, alkaline amphiboles, astrophyllite, natrolite, and...

In this paper, we describe the metamorphic conditions of Fe-rich granulite and variations in rare earth elements (REE) between peak garnet porphyroblasts and secondary garnet coronae. The Fe-rich granulites were collected from Vesthaugen, Sor-Rondane Mountains, East Antarctica, and consist mainly of cordierite, garnet, spinel, perthite, K-feldspar, plagioclase, and orthopyroxene or sillimanite. Temperatures estimated from perthitc–mesoperthitic feldspar compositions, experimentally calibrated ge...
