introduction thermodynamically, the surface waters in mountain environments are unstable and their chemical composition is a reflection of water-rock interactions. few studies have also been undertaken on the geochemistry of the surface waters in mountain environments. hence, this paper deals with the source of elements as well as the chemistry of the stream which drains from the caldera of bid...

Abstract New detrital U–Pb zircon ages from the Sanandaj–Sirjan metamorphic zone in Zagros orogenic belt allow discussion of models late Neoproterozoic to early Palaeozoic plate tectonic evolution and position Iranian microcontinent within a global framework. A total 194 valid age values 362 grains were obtained three garnet-micaschist samples. The most abundant population included Ediacaran ag...

The study was carried out in the purposively selected Senapati and Thoubal districts of hill and valley regions of Manipur State of India. Two blocks from each of the above selected districts were selected randomly and further from each block four villages were also selected randomly. 30 dairy farmers from each village were selected randomly and thus collected data from 240 respondents through ...

Rock fragmentation is one of the desired results of rock blasting. So, controlling and predicting it, has direct effects on operational costs of mining. There are different ways that could be used to predict the size distribution of fragmented rocks. Mathematical relations have been widely used in these predictions. From among three proposed mathematical relations, one was selected in this stud...

the aim of this study is prospecting of iron and manganese in the balvard 1:100000 sheet which is situated in sanandaj - sirjan structural zone utilizing index overlay and fuzzy logic methods in the gis. in this study, the layers for integration, alterations, geological, geophysical, geochemical and structural data based on stream sediments, airborne magnetometeric and remote sensing studies. b...
