The Alta Floresta Gold Province (PAAF) is abundant in gold deposits and, located the state of Mato Grosso, Brazil, an ideal place to study geoelectric signature mineralization. Auriferous mineralization occurs along shear zones quartz veins and disseminated granites this region. Ores are associated with oxides sulfides, mainly pyrites. To identify primary or continuities mineralized zones, data...

The Bolboli2 copper ore deposit is located about 110 km southwest of Kerman and lies in the Dehaj-Sarduieh metallogenic belt (Kerman Cenozoic Mamatic Arc, KCMA). This ore deposit is hosted by the Eocene extrusive igneous rocks (tuff, agglomerate, andesite, and dacite) and the Oligo-Miocene intrusive igneous body (granodiorite). These rocks are host the propylitic, phyllic, and silicic alteratio...

Galali orebody is located in Sanandaj-Sirjan zone in west of Iran in the Karamkhani slops in Almogholagh mountains. The main ore is magnetite association with hematite, goethite, secondary limonite, malachite and pyrite. This orebody is located on north Galali fault; mineralization is made by fault movements in this orebody. Three types of ores have been seen in the Galali orebody as below: Typ...

The supplementary data have included a full range of TEM pictures of the post-run samples, including 400 oC calcinated MoO3/H-ZSM-5 samples (coked) and the parent H-ZSM-5 (coked), showing the distribution of Mo clusters on the zeolite crystallite external surface, and the observed coke deposition upon the spreading of the Mo species. The Figures S1-S9 are the complementary of the Fig. 8 in the ...

Direct numerical simulations are performed of turbulent planar Couette flow which are seeded with two-way coupled particles at low volume concentration. Based on an understanding of the development of particle stress (horizontal momentum carried vertically on average by the particle phase) in monodisperse systems at various particle Stokes numbers, several bidisperse and continuously polydisper...

Abstract The ABM deposit, Finlayson Lake district, Yukon, Canada, is a bimodal-felsic, replacement-style volcanogenic massive sulfide (VMS) deposit (19.1 Mt @ 6.6 wt % Zn, 0.9 Cu, 2.0 Pb, 1.4 g/t Au, and 148 Ag) hosted by Late Devonian continental back-arc–related volcanosedimentary rocks of the Kudz Ze Kayah formation. VMS-related hydrothermal alteration associated with extends >1 km be...

The trace element contents on the surface originated from mineralization would depend to the thickness of the calcrete layer above the ore deposit on the surface. A very thick layer of calcrete may not allow for much dispersion of the elements of interest in the surface. These elements may be concentrated in non-magnetic and magnetic part of calcrete. Based on the current research, mineralogica...

Geological and geochemical studies of gold mineralization in Bode-Saadu axis, Southwestern Basement Complex, Nigeria have been conducted order to study their mode occurrence, structural settings, pattern distribution potential. reveal that granite gneiss are the prominent rocks area exist north-eastern, north-western southwestern part whereas mica amphibole schist occur as low-lying exposure. P...
