The Simorgh area is located about 113 km southwest of Nehbandan. Initial prospecting conducted by satellite data ASTER sensor with spectral angle mapper method, in order to identify probable alteration zones. The data, compared with field observations, have provided satisfactory results. This area consists of Eocene volcanic units in which various sub volcanic rocks have intruded in them. The m...

The material source and the evolution of ore-forming hydrothermal fluids Xiaojiashan gold deposits remain controversial. We carried out a mineralogical characteristics analysis, trace elements sulfur isotope composition fluid inclusion microthermometry in order to explore sources, conditions, process this deposit. Gold mineralization can be divided into three stages: quartz-pyrite stage, quartz...

The Birimian of West African Craton (WAC) is known for its gold potential. Among structures, N-S and NE-SW trends have been defined as controlling mineralizations in Kedougou-Kenieba Inlier (KKI), whereas some these structures are not gold-bearing. To determine related to mineralization, airborne electromagnetic data collected during the “Système Minier” Mali processed interpreted. Identified l...

Knowledge-and data-driven approaches are two major methods used to integrate various evidential maps for mineral prospectivity mapping (MPM). Geological maps, geochemical samples and data from known gold deposits were collected in the western Junggar area, Xinjiang Province. The geological and a spatial database for geological and mineral occurrences were constructed for the studied region. A w...

The Mafic complex of Mishow is exposed in the north-western part of Iran, in the East Azerbaidjan Province (SW of Marand). Two different types of mineralization, sulphides and oxides, occur in the intrusion complex. The sulphide ore bodies are mainly composed of pyrrhotite accompanied by chalcopyrite, pentlandite, sphalerite, pyrite and troilite. The oxides mineralization consists of ilmenite a...
