Journal of Quaternary Science, EarlyView.ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

Assessment of Karstification Degree in the Copacabana Group for a Tailings Dam Foundation, South Andes, Peru [PDF]
, 2013 The world-wide occurrence of carbonate rocks is extensive, and Peru is no exception. Many mining facilities are located in or on carbonate rocks. Under specific conditions, carbonate rocks show varying degrees of karstification, which represent a ...

Journal of Quaternary Science, EarlyView.ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.

Mass Spectrometry Reviews, EarlyView.ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Study on the development model of deep carbonate paleokarst reservoirs in the Tarim Basin
Carsologica SinicaAs a critical hydrocarbon-bearing basin in China, the Tarim Basin contains exceptionally abundant oil and gas resources within its Paleozoic marine carbonate formations, particularly in the deep subsurface where it exhibits significant exploration ...

Oreocharis konkakinhensis (Gesneriaceae) sp. nov. from the Central Highlands, Vietnam
Nordic Journal of Botany, EarlyView.Oreocharis konkakinhensis, a new species of Gesneriaceae, is described and illustrated from the Central Highlands, Vietnam. The new species is morphologically most similar to Oreocharis phuongii, a recently described species from central Vietnam. However, it clearly differs from the latter by having stems without stolons, subulate bracts, yellow inner ...

Vadose zone air as a biogenic source of methane in Nerja Cave system (South of Spain) [PDF]
, 2018 Subterranean air in karst cavities has often low methane contents in comparison to atmosphere and so karst systems have been considered a sink of atmospheric methane. Methane-oxidizing bacteria have been hypothesized as responsible for CH4 depletion in
