oeeuring in the Sangan arca was fonned within two different rock groups· graitoids and skarns. Based on the new amphibole classification and nomenclature, the general fonnula of amphibols IS (AB2C,T,O"OH),. Amphibole of granitoids is a ferroedenite in which Si = 6.87 - 7.75, CaR> 1.5, (Na+K)A > 0.5 and Ti < 0.5. Skarn amphiboles are mostly developed within amphibole skarns and gamet-pyr...
Summer catchment basins surrounding the city of Tehran, due to their remoteness from atmospheric pollution and urban manifestations, is considered as a place for exploring and recreating for many people, and as a place for money making out of restaurants attracting many tourists for others. Sangan is taken into consideration as one of the most beautiful valleys in Northwest of Tehran. The summe...
Detailed studies are done in order to investigate the ore body in Sangan mine. Analyses results showed very low amount of gold in mineralized zone, (max 32 ppb). It is indicated that there is a positive relation between Au, S and As whereas there was no special relation between Au and Cu. Therefore Au can not be found along with Cu sulfides such as chalcopyrite. The LREE elements are higher tha...
The Sangan processing plant consists of four consecutive low-intensity magnetic separation steps with the same magnetic field intensity of 1300 Gauss for upgradation of iron ore. Hence, the iron ore minerals with lower magnetic susceptibility or interlocked with gangue minerals have no opportunity for upgradation, and proceed to the tailing dam. Flotation is a powerful technique for upgradation...
Dardvey iron skarn ore deposit is located in the central part of the Sangan mininig area, northeastern Iran. In this study, silicate geothermometr were used to estimate the formation temperatures of skarn zones in Dardvey Fe-skarn deposits. The main metamorphic minerals in prograde and retrograde skarn zones are garnet-clinopyroxene-tremolite/actinolite-amphibole-chlorite-epidote-feldspar-phlog...
Inovasi adalah sesuatu hal yang baru mengangkat dari ilmu pengetahuan, serta dapat memberikan manfaat dalam kehidupan manusia. Ilmu pengetahuan sangat dibutuhkan untu pengembangan inovasi. Tanpa adanya inovasi tidak akan berjalan sebagaimana mestinya. Bahkan bisa saja salah sasaran, bertahan lama dan hanya menjadi angan-angan. sangan berguna di segala bidang kehidupan, oleh karena itu, memahami...
Pandemic Covid-19 membawa dampak yang cukup signifikan terhadap proses belajar mengajar. Didasari perubahan cara secara luring menjadi daring baik pada mata kuliah teori maupun praktik, tentu perlu mendapatkan perhatian khusus dalam penyampaian materi perkuliahan. Oleh karena itu adanya pengembangan media dapat dipelajari oleh mahasiswa mandiri. Penelitian ini bertujuan merancang, mengimplement...
Pada dasarnya guru adalah sebagai salah satu komponen dalam kegiatan belajar mengajar (KBM), harus memiliki kreativitas dan profesinalisme karena posisi yang sangan menentukan keberhasilan pembelajaran. Masalah dihadapi baik pemula maupun sudah berpengalaman ialah meningkatkan hasil belajar. Hal ini menuntut adanya kereativitas profesionalisme kerja bertugas merencanakan melaksanakan serta meni...
