Economic mineral deposits found in oceanic terranes include: mesothermal gold-quartz veins, Cyprus-type massive sulphide, podiform chromite. platinum or cobalt associated with nickel sulphides, as well as asbestos and jade deposits. These are rither hosted by, or otherwise closely associated with oceanic crustal or mantle lithologies. Mesothermal gold-quartz veins and related placers are histor...

the potential risk of metal accumulation in periurban agricultural areas is a matter for concern.the climate characteristics and carbonate content of calcareous agricultural mediterranean soils typical inthese areas favour metal accumulation at the surface level; however there is also a risk of potential metalmobility. our study focuses on the soil properties affecting metal mobility in these s...

Mineral paragenesis of rodingitized basic rocks of Iranian ophiolites are presented and metasomatic reactions between Ca+2 bearing aqueous fluids issued during serpentinization of host ultramafic rock – with magmatic minerals of basic rocks leading to present paragenesis of rodingites are discussed. It is concluded that Ca+2 rich aqueous fluid in equilibrium with serpentinite has high Ca+2 chem...

The study area is located ~50 km in the north of Tehran capital city, Iran, and is a part of central Alborz Mountain. The intrusive bodies aged post Eocene have intruded in the Eocene volcanic units causing hydrothermal alterations in these units. Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) images were used to map hydrothermal alteration zones. The propylitic, phyllic...

magnetic susceptibility has been extensively used to determine the magnetic properties of rocks for different applications, such as hydrocarbon or mineral explorations. this magnetic quantity can be directly measured in an accurate but time-consuming operation, or it can be mathematically approximated using a reliable procedure to achieve a desired accuracy. the poisson theory is one of the mos...

Revealing prospective locations of hydrothermal alteration zones (HAZs) is an important technique for mineral prospecting. In this study, we used multiple criteria inferred from Landsat-8 OLI, Sentinel-2, and ASTER data using a GIS-based weighted overlay multi-criteria decision analysis approach to build model the delineating deposits in Khnaiguiyah district, Saudi Arabia. The utilized algorith...

The ground magnetic survey was carried out using a Scintrex proton precession magnetometer to map subsurface structures and mineralization potentials at the Alajawa area in Shanon, Kano State. 2D forward modeling delineation of geological that are potential zones. Surfer 15 software used produce residual contour map. A total five (5) profiles anomalies were modeled Mag2dc software. mineral loca...

The northwestern part of the Kerman Cenozoic magmatic arc (KCMA) contains many areas with porphyry copper mineralization. In this research, we used the advanced space-borne thermal emission and reflection radiometer (ASTER) and Enhanced Thematic Mapper plus (ETM+) images of this region to map the distribution of hydrothermally altered rocks, based on their mineral assemblages. The spectral meas...
