kuh- e -zar gold deposit located 35 km west of torbat-e-heydaryeh, (khorassan e- razavi province), east of iran. this deposit is a specularite-rich iron oxide type (iocg). this mine is situated within khaf-bardascan volcanic plutonic belt. based on recent exploration along this belt, several iocg type system plus kuh-e-zar deposit are discovered. in the study area, several type of tuff and lava...

A predominant sigmoidal clinoform deposit extends from the Yangtze River mouth southwards 800 km along the Chinese coast. This clinoform is thickest ( 40m) between the 20 and 30m isobaths and progressively thins offshore, reaching water depths of 60 and 90m and distances up to 100 km offshore. Clay mineral, heavy metal, geochemical and grain-size analyses indicate that the Yangtze River is the ...

The accuracy of data-driven predictive mineral prospectivity models relies heavily on the training datasets used. These are usually trained using data for “known” deposit locations as well “non-deposit” that based randomly generated point patterns. In this study, related to Seabridge Gold Inc Iskut project, an epithermal Au in northwestern British Columbia (BC), Canada, used test utility modeli...

An expert system applied to the control of mineral process unit operations is, by its nature, the site best operating practice, having been designed by the local experts in conjunction with consulting metallurgists. The “common sense” layer in a MET (MinnovEX Expert Technology) solution determines an appropriate action for the current operating conditions through a developed heuristic model of ...

Although native bismuth is a relatively common mineral, native antimony is less abundant, and Sb-Bi alloys are relatively rare phases in Nature. Sb-Bi alloys and Ag-Cu-Pb-Sb-Bi sulphosalts have been discovered in the Jialong vein-type Cu-Sn deposit in North Guangxi, South China. The Jialong deposit is hosted by schist within the contact zone of a Neoproterozoic granite. Four stages of ore forma...

pb-zn deposits in the kurdistan region, northern iraq, have occurred mainly as a stratabound and open-space filling ore bodies. they are hosted by dolostone and dolomitic-limestone of platform carbonates. the ore deposits at the studied dure and lefan areas are respectively hosted by kurra chine (upper triassic) and bekhme (upper cretaceous) formations. pyrite, sphalerite and galena are the maj...

Geologic processes strongly influence water and sediment quality in aquatic ecosystems but rarely are geologic principles incorporated into routine biomonitoring studies. We test if elevated concentrations of metals in water and sediment are restricted to streams downstream of mines or areas that may discharge mine wastes. We surveyed 198 catchments classified as "historically mined" or "unmine...

The present study aims to investigate the textural, mineralogical and geochemical characteristics of lean grade placer monazite from Bramhagiri beach sand deposit assess possibility for its use in industrial applications. bulk back dune with 18 samples showed elements uranium thorium traces, phosphorus calcium minor amounts, alumina, silica titanium major amounts. Since apatite was absent this ...

The application of remote sensing sciences in the field geology is very diverse and wide. One its most important applications earth geological mapping. Mineral exploration using techniques done different ways, one them mapping alteration zones related to mineral resources. Given importance geosciences today's industry given that deposit-related areas are exploratory keys. this review study meth...
