The Bolboli2 copper ore deposit is located about 110 km southwest of Kerman and lies in the Dehaj-Sarduieh metallogenic belt (Kerman Cenozoic Mamatic Arc, KCMA). This ore deposit is hosted by the Eocene extrusive igneous rocks (tuff, agglomerate, andesite, and dacite) and the Oligo-Miocene intrusive igneous body (granodiorite). These rocks are host the propylitic, phyllic, and silicic alteratio...
this study tries to show that how viewpoint functions in discourse. as it will be clarified, it is highly related to the intention of the speaker/writer, and as a result, the orientation (s)he adopts in the discourse. deictic markers function as discourse markers to fix and anchor time, place, agent, and other discursive elements. in this way, the viewpoint adopted by the enunciator/utterer is ...
The sediment-hosted stratiform copper–silver mineralization in the San Marcos area of Coahuila, northeastern Mexico occurs predominantly at an Early Cretaceous redox boundary between footwall siliciclastic red beds Formation and hanging-wall carbonate strata Cupido Sabinas basin. hypogene is mainly present as chalcocite-group minerals, with additional bornite chalcopyrite, everywhere both disse...
section{introduction} the concept of {sl cartan geometry} appeared at the beginning of the twentieth century, when {e}lie cartan was working on the so-called {sl equivalence problem}, the aim of which is to determine whether two given geometric structures can be mapped bijectively onto each other by some diffeomorphism. this problem can be considered in many different contexts, such as ...
طی این مطالعه 37 گونه شامل 44 آرایه درون گونه ای داینوفلاژله ها شناسائی شد. نمونه برداری ها طی سال های 1379 تا 1391 انجام گرفته است. داینوفلاژله های مورد مطالعه متعلق به 1 رده، 4 راسته، 9 خانواده و 13 جنس هستند و از اکوسیستم های آبی مختلف داخلی جمع آوری شده اند. بیشترین تعداد یعنی 25 گونه (31 آرایه درون گونه ای) متعلق به رودخانه هاست. در این مطالعه تجزیه و تحلیل مختصری نیز از نظر اکولوژیک و جغر...

This study encompasses the ore mineralogy, textures and sulphide trace element chemistry of Palaeoproterozoic Lovisa stratiform Zn-Pb deposit stratigraphically underlying Fe Formation in Bergslagen province (Sweden). We investigate relative timing formation subsequent modifications its ores relation to c. 1.87–1.80 Ga Svecokarelian orogeny. The consists several different types. massive sphaleri...
The study area is located in the Varzeghan city and in the province of the East Azerbaijan. Mineralization in the Hizeh –Jan area is gold mineralization type and associated with quartz and quartz - carbonate veins and veinlets, which is occurred in the Eocene volcanic rocks with andesite composition. The most significant alteration in this area, is developing of propylitic, argillic and silic...
Kariro Pb prospect area, which is located in northwest of Boshruyeh, occurs as vein-veinlets, open space filling, and cement of fault breccia in Middle Jurassic metamorphosed shale (slate) unit of Baghamshah Formation. Mineralization zones contain dolomite (70-85%) and galena (0.5-2.5%) with small amounts of pyrite, quartz, and calcite. Dolomitization and silicification of host rock are the mos...
