salman and resalat oilfields are such marine oilfields that are in vicinity of each other. there is resalat oilfield in distance about 80-90 kilometers from lavan island in persian gulf. this oilfield is located in 25 kilometer southwest in reshat oilfield. salman oilfield is located in vicinity of water border line of united arab emirate in 140 kilometers of south of lavan island. this oilfiel...

This paper describes the use of lichen chemistry to assess airborne tungsten and cobalt in Fallon, Nevada, where a cluster of childhood leukemia has been on going since 1997. Lichens and their rock substrates were collected from Rattlesnake Hill within Fallon as well as from four different rock outcrops located north, east, south, and west of Fallon and at least 20 km away from the town center....

Driven by the needs of engineered underground systems, the field of rock mechanics is evolving to address the interactions of in situ mechanical, thermal, hydrologic, and chemical processes and their effects on system performance. Important technical issues include understanding how the relevant loads and gradients drive in situ processes; rock mass variability, discontinuity, and heterogeneity...

Abstract An extensive subsurface investigation evaluating the geothermal energy resources and underground thermal storage potential is being carried out in southwestern part of Swiss Molasse Basin around Geneva Canton. Among this process, evaluation petroleum source-rock type an important step to understand system responsible some oil gas shows at surface subsurface. This study provides a first...

With the constant consumption of conventional oil and gas resources, unconventional oil and gas resources with great resource potential such as tight oil have gradually been valued and become the new exploration area. Jimsar Sag is the key tight oil exploration and development block in Junggar Basin of Northwestern China. Based on the data sets of geology, oil production test, logging, rock thi...

petrography, modal analysis of sandstones and major elements geochemistry of shales of early cambrian zagun formation in sarbandan section, central alborz, are used to identify their provenance (including parent rocks, tectonic setting and paleo-weathering). petrography of the sandstones and plotting their point counting data on qt44, f47, l9 and qm44, f45 ,lt11 diagrams imply that they are ark...

Exploratory geochemistry studies of heavy minerals, stream sediments and rock in Asbkhan region, Heris, northwest Iran

Halliday, A.N., Davidson, J.P., Hildreth, W. and Holden, P., 1991. Modelling the petrogenesis o1 high Rh/Sr silicic magmas. In: A. Peccerillo (Guest-Editor), Geochemistry of Granitoid Rocks. Chem. Geol., 92: 107-114. Rhyolites can be highly evolved with Sr contents as low as 0.1 ppm and Rb/Sr > 2,0(t0. In contrast, granite batholiths are commonly comprised of rocks with Rb/Sr < l 0 and only rar...
