The Qin-Hang Metallogenic Belt (QHMB), an important metallogenic belt in South China, hosts Cu and W–Sn polymetallic deposits. Tongshanling ore field the QHMB is characterized by coexistence of Cu- W-bearing deposits, which are related to granodiorite granite porphyry. This study examined whole-rock geochemistry, geochronology, Sr–Nd–Hf isotopes determine genetic relationship between diverse or...

Compositional features of a total 1887 gold alluvial particles from six localities to the south Loch Tay in central Scotland were interpreted establish different types source mineralization. Populations each locality grouped according alloy and inclusion signatures. Inclusion suites provided primary discriminant with Group 1 showing narrow range simple sulphide sulphoarsenide species, whereas w...

Increases in the magnitude of positive Ce anomalies zircons from igneous rocks are often interpreted to be controlled by progressive melt oxidation and have been used provide evidence for elevated redox state magmas associated with porphyry Cu deposits. In this paper, we test idea comparing trace element compositions Resolution Cu-Mo deposit, Arizona, numerical models systematics zircon-melt pa...

The Lut Block is a potential porphyry-style mineralized region in Iran including the well-explored Shadan porphyry gold-copper deposit, which has an extensive zone of gold- and copper-bearing stockwork-like sheeted veins. structural setting this deposit key to understanding genesis mineralization. Our field studies show that mineralization occurs as steeply dipping ore bodies along NW–SE transp...

the role of some ring structures in the distribution of porphyry copper deposits in south kerman porphyry copper belt is discussed. in the study area, ring structures are circular or elliptical shaped features which are partly recognized on satellite images. in this study, landsat multispectral images were used to identify ring structures in the area. the rudimentary identification stages of th...

maherabad prospect area, which is studied in detail, is the first porphyry cu-au mineralization in the east of iran. based on relation of mineralization with subvolcanic intrusive bodies mostly monzonitic with porphyry texture, extent and types of alteration including potassic, sericitic- potassic, quartz- sericite- carbonate- pyrite, quartz- carbonate- pyrite, silicification- propylitic, propy...

The Sungun copper deposit is located in about 40km north west of Ahar city in the east Azarbaigan province of Iran. The total geological ore deposit is estimated to be 740 million tons. In this study using all information from exploration and geotechnical studies of the area, final pit limits of Sungun copper deposit is designed by the 2-D Lerchs & Grossmann Algorithm. By this method, from 740 ...
