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, ...

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...

to evaluate the relationship between total organic carbon (toc) and rock-eval s2 (petroleum potential) of petroleum source rocks, atotal of 180 outcrop samples from the black organic matter–rich facies of mesozoic strata from a locality of southwest of iran wereinvestigated using rock-eval vi pyrolysis and leco carbon analyzer. the linear regression is applied to determine the correlationbetwee...

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 ...
