Despite the fact that rock glaciers are one of the most common geomorphological expressions of mountain permafrost, the impacts of their solute fluxes on lakes still remain largely obscure. We examined water and sediment chemistry, and biota of two neighboring water bodies with and without a rock glacier in their catchments in the European Alps. Paleolimnological techniques were applied to trac...

Depositional environment and source potential of the different organic-rich levels of Devonian age (up to 990m thick) from the onshore EC-1 well (Southern Tunisia) were investigated based on the analysis of more than 130 cutting samples by different geochemical techniques (Rock-Eval pyrolysis, GC-MS). The obtained results including Rock Eval Pyrolysis data and biomarker distribution (terpanes, ...

The present study focuses on source rock evaluation of the Sargelu Formation by using core chips rocks collected from well Atrush-2, Duhok, Kurdistan Region-Iraq. Rock-Eval pyrolysis and vitrinite reflectance were executed. Subsequently, selected parameters used for 1-D Basin Modelling calibration. upper part formation mainly comprises argillaceous limestone with low content organic matter (0.6...

Groundwater shortage and pollution are critical issues of global concern. In Wulian County, a typical hilly area, groundwater is the main source water supply. This study investigates current situation in City through analysis chemistry characteristics, quality evaluation, health risk evaluation. After controlling factors chemical components ion sources, sources were determined. The results show...

We use a relatively simple model of an underground current source co-located with the earthquake hypocenter to estimate the magnitude of the seismotelluric current required to produce observable ground signatures. The Alum Rock earthquake of 31 October 2007, is used as an archetype of a typical California earthquake, and the effects of varying the ground conductivity and length of the current e...

Eocene and Lower Oligocene rocks are potential source for crude oil accumulations in the Hungarian Palaeogene Basin. To enhance understanding of hydrocarbon system, this study (i) assesses petroleum formations, (ii) characterises rock facies accumulated oils, (iii) provides an oil-to-source correlation. Rock-Eval data samples from three boreholes (W–1, W–9 W–12) show that most formations mature...

dezful embayment contains several potential source rocks deposited in tectonically active environments. existence of various source rocks with different geological ages makes this area one of the most prolific regions throughout the middle east. the pabdeh formation (lower paleocene-eocene), the gurpi formation (santonian-masstrichtian), the kazhdumi formation (albian) and the gadvan formation ...

Gazestan magnetite-apatite deposit is located in Central Iran and Bafq region, which has been occurred in form of veins, veinlets, and small apatite lenses as well as magnetite in metasomatic rock types such as green chlorite-actinolite rock units. These rocks are situated in the carbonate-volcanic complex of Upper Precambrian-Lower Cambrian Rizo formation. In this study, staged factor analysis...
