one of the major strengths of a geographic information system (gis) in geosciences is the ability to integrate and combine multiple layers into mineral potential maps showing areas which are favorable for mineral exploration. these capabilities make gis an extremely useful tool for mineral exploration. several spatial modeling techniques can be employed to produce potential maps. however, these...
Submitted: Jul 19, 2013; Accepted: Sep 3, 2013; Published: Sep 11, 2013 Abstract: The study of isotopic ratios of oxygen and carbon has gained importance to determine the origin of ore bearing fluids, carbon origin and also to determine the formation temperature of non-sulfide lead and zinc minerals. In order to determine the origin of fluids and carbon existing in zinc carbonate minerals in Ch...

W ith nearly two-thirds of the population afflicted, the Nuu-chah-nulth Indians of Vancouver Island in British Columbia have one of the highest rates of arthritis in the world. Often passed down family lines, the genetics of arthritis in this unique population was studied extensively during the 1980s by Richard Ward, now head of the Institute of Biological Anthropology at the University of Oxfo...
The investigated area is a part of Sabzevar ophiolite melang of North Eastern Iran which is important from two points of view, geology and its potential of Economic Mineral deposits. The main geological units in both Chah Yabu and Cheshmeh Palang areas are serpentinized peridotite, gabbro, diabasic dykes of Upper Cretaceous and Tertiary volcanic rocks which are mainly altered. Cheshmeh Palang a...
chah?rmah?l-o-bakhtiy?r? province has an area of some one percent of the area of iran and is situated in the northern basin of karun river, which is one of the most vital flows of the south-west iran. for various reasons, the region has been ignored in the national archeological studies. in a quick glance, the present study seeks to show the significance of the findings obtained in the course o...
Chah Sorb deposit is located about 66 Km north of Tabas and 16 Km north-west of Shirgesht village. The mineralogy is simple; galena is the main primary mineral and cerussite is the main secondary mineral. Sphalerite, pyrite, chalcopyrite, tetrahedrite are other main minerals. Secondary minerals are anglesite, malachite, flourite, wulfenite, minium, azurite and Fe-hydroxids. Some important alter...
Chah-Shoor kaolin mine is located about 150 km southeast of Isfahan and also located in the central Iran structural zone, Urumieh-dokhtar volcanic belt. Eocene Igneous rocks consist of andesite, tuffs and quaternary deposits have covered the area. Based on petrographic studies, the main minerals in the volcanic rocks are K- feldspar, quartz and plagioclase. Hydrothermal alteration has produced ...
The Chah-Shur clay deposit is located in150 km southeast of Isfahan. Eocene igneous rocks and Quaternary deposits cover the area. Eocene volcanic rocks include andesite and tuffs which relating to magmatic activities of Urumieh-Dokhtar magmatic belt. Alteration of the vitric and lithic tuff units has produced the clay deposit. Based on the petrographic studies, the main minerals in tuff uni...
