Simulation of rock salt dissolution and its impact on land subsidence [PDF]

, 2014
Extensive land subsidence can occur due to subsurface dissolution of evaporites such as halite and gypsum. This paper explores techniques to simulate the salt dissolution forming an intrastratal karst, which is embedded in a sequence of carbonates, marls,

Marine Isotope Stage 4 glaciation in northern England, UK: Evidence from Victoria Cave, North Yorkshire

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.

Management Assessment in Karst Areas

Acta Carsologica, 2016
Najpomembnejša odgovornost pri upravljanju s svetovno dediščino je dvojna. Po eni strani bi morali ohraniti integriteto in kakovost naravnega okolja, po drugi pa omogočiti dostop čim širši javnosti. Čeprav je v tej trditvi morda nekaj dvoumnosti pa ni dvoma, da se osnovna elementa tega vprašanja dopolnjujeta in da enega ni mogoče v celoti rešiti, ne da

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 ...

Desertification in karst areas: A review

Earth-Science Reviews
Desertification in karst is an effect of climate change and not sustainable anthropogenic activities, the combination of which, however, causes the gradual loss of karst natural resources, such as soil, vegetation, and groundwater. A considerable percentage of global karst areas is found in drylands, characterized by negative water balance and scarce ...

3D effects of seawater on electrical resistivity tomography near shorelines—Challenges and possible solutions inferred from synthetic and field data

Near Surface Geophysics, EarlyView.
Abstract Electrical resistivity tomography (ERT) is one of the most widely used geophysical techniques for hydrogeological questions, such as investigating the groundwater transition zone between land and sea. The interpretation of 2D coast‐parallel ERT profiles is challenging because most of the electrical current flows through the highly conductive ...

Chalcone-Synthase-Encoding RdCHS1 Is Involved in Flavonoid Biosynthesis in Rhododendron delavayi

Molecules
Flower color is an important ornamental feature that is often modulated by the contents of flavonoids. Chalcone synthase is the first key enzyme in the biosynthesis of flavonoids, but little is known about the role of R.
