Hassan Abad Au-Sb prospect area is located in north of Khorasan Razavi Province about 45 km souht of Neyshabour. Volcanic rocks (rhyolite, rhyodacite, trachyandesite and andesitic-basalt) and sub-volcanic intrusive (Eocene-Oligocene) such as biotite diorite porphyry, biotite hornblende diorite porphyry, hornblende monzonite porphyry, biotite micogranite, micogranodiorite, and granodiorite were ...

Gradient and MS Complex on sub-domains. Gradient pairs are computed within a sub-domain using Algorithm 1 and Algorithm 2 from section 4. The cell complex of the sub-domain is extended to include the set of cells that are incident on the shared boundary of sub-domains but gradient pairs are computed only on the initial sub-domain cell complex (see Figure 1b). Thus, we obtain identical pairings ...

Waste ore samples (pH 3.0) were collected at an acid mine drainage (AMD) site in Anhui, China. The present acidophilic microbial community in the waste ore was studied with 16S rRNA gene clone library and denaturing gradient gel electrophoresis (DGGE). Eighteen different clones were identified and affiliated with Actinobacteria, low G + C Gram-positives, Thermomicrobia, Acidobacteria, Proteobac...

With the era of big data, prediction and evaluation geological mineral resources have gradually entered into a new stage from digital prospecting to intelligent prospecting. The theoretical method data mining can contribute deep resource evaluation. This paper extracts ore-causing ore-caused anomaly information based on text technology, constructs regional conceptual model data. First, we set u...

Ore bodies generate natural electrical fields that are measurable at the ground surface. The surface signature of this field is called a self-potential anomaly. We developed sandbox experiment to monitor evolution anomaly associated with redox processes mediated by bacterial activity buried metallic object crossing water table. A Bio-Electrochemical Cell (BEC) formed metal bar connecting upper,...

mapping the edges of magnetized bodies is fundamental to the application of magnetic data to geologic mapping. whether as a guide for subsequent field mapping or as a predictive mapping tool in areas of limited exposure, delineating lateral magnetization changes provides information on not only lithological changes but also on structural regimes and deformation styles and trends. adding contact...

The East Pana intrusion is a part of the Paleoproterozoic Fedorova–Pana complex (FPC), which belongs to group Fennoscandian layered mafic–ultramafic massifs. This article discusses magmatic stratification intrusion, as well Cu-Ni and platinum-group elements (PGE) mineralization (PGE zones A, B C) in its various parts with total length more than 20 km, including Chuarvy PGE deposit. Based on who...
