The Hatu area, West Junggar, Xinjiang, China, is situated at a potential gold-copper mineralization zone in association with quartz veins and small granitic intrusions. In order to identify the alteration zones and mineralization occurrences in this area, the Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper (ETM+), Quickbird, Hyperion data and laboratory measured spectra were combined ...

Different types of iron oxides deposits have been identified along the Khaf – Dorouneh volcanic and plutonic belt in north east of Iran. Kuh-e-Zar is one of these ore deposits known as Fe- oxide gold deposit. The main purpose of this paper is to detect and discriminate the iron oxide minerals in this area based on the ETM+ data. Data processing has been done by ENVI (Environment for Visualizing...

the northwestern part of the kerman cenozoic magmatic arc (kcma) contains many areas with porphyry copper mineralization. in this research, we used the advanced space-borne thermal emission and reflection radiometer (aster) and enhanced thematic mapper plus (etm+) images of this region to map the distribution of hydrothermally altered rocks, based on their mineral assemblages. the spectral meas...

sar-kuh porphyry copper deposit is located 6 km southwest of the sar-cheshmeh copper mine, kerman province, iran. based on field geology, petrography and fluid inclusions studies, four alteration types have been identified in the sar-kuh area. early hydrothermal alteration formed a potassic zone in the central parts of mamzar granite/grano-diorite stock and propylitic alteration in its peripher...

In This Issue In This Issue Pulling on a cytokine he extracellular matrix (ECM) acts as a storage facility for tons of factors waiting to do business in the cell. Annes et al. (page 723) show that the ECM anchoring of one factor, the cytokine TGF-␤ , is essential for its activation. The anchoring may give cells something to pull against, with the pulling mediating the activation. Most TGF-␤ is ...

In the course of geological prospecting fulfilled with participation FGBI TsNIGRI within Chayangro ore cluster Dodykhta-Uryakh region in southeastern Baikal-Patom metallogenic province, Dzhalagun lode gold prospect field same name was studied and its economic significance has been proved. It substantiated that is closely similar to typical deposits Bodaibo sense formation phasing, character hyd...

Exploration is a key fundamental step in the process of any uranium mining activity. Moreover, new deposit has been discovered context mine development. The objective present research studies to apply borehole redox mapping technique as guide for exploration sedimentary environment. Tarat formation study area Arlit divided into four units (U4, U3, U2, and U1) such Unit4 (U4) consists reduced gr...

The productive mineralization of the Sheikhdzheili-Zengiboba area is associated with metamorphogenic transformations rocks Urusai, Karauzyak, Kuyanchik, Sheikhdzheili suites, metamorphosed under conditions green schist facies. mineralized zones site are confined to narrow faults in tectonic northeast and northwest directions. main form manifestation gold-bearing small steeply dipping veins, len...
