The southern part of Skull Valley has potential for shallowly buried mineral deposits. The most likely deposit type is either skarn/porphyry copper deposits, perhaps with surrounding polymetallic lead-zinc-silver replacement deposits or "distal disseminated" gold-silver deposits. The area (1) is structurally complex with both thrust and high-angle faults, (2) contains lithologic units favorable...

The Malmyzh ore cluster, which was revealed in 1970–1976, is located the central part of Khabarovsk territory, on right bank Amur River. deposits are timed to Late Cretaceous intrusions that break through sedimentary formations Early Cretaceous. Mineralization controlled by intrusive dome structures.

In vector model, the boundary between features is stored and shown categorically in an absolute way, in other words Membership or non-membership of a point in each polygon is known which can be 0 or 1. For showing real world and its projection on map, because of the uncertainty on the border of the boundary between phenomena and spatial data, there is some uncertainty and vagueness in drawing a...

Indonesia is a country that has several world-class copper-gold deposits, particularly in eastern Sunda arc. The Hu’u complex prospects the surface as lithocap of extensive epithermal style alteration, but some were detected associated with porphyry beneath surface. study focuses on hydrothermal breccia cement factor influencing system district. methods used mineralogical analysis petrography a...

Response surface methodology (RSM) is one of the most effective tools for optimizing processes, and it has been used in conjunction with Analysis Variance (ANOVA) test to establish effect input factors on output factors. However, when this mineral flotation, its polynomial model usually performs poorly. An alternative use artificial neural networks (ANNs) such situations. Within context, ANOVA ...

A review of gold and bearing base metals deposits in Chile, indicate the existence at least six different type ore deposits, most largely formed during Cenozoic with predominance Miocene. Mesozoic are common but less relevant regarding their size content. These hydrothermal genetically associated subduction related Andean arc magmatism. Due to its relationship episodic magmatism migrating eastw...
