... to 55% under storm conditions; Mahler and Massei 2007 ). In the eastern portion of Austin, clays (e.g. Del Rio Clay, Taylor Clay, and Walnut Formation) overlie the Edwards Aquifer and limit the infiltration of natural and anthropic recharge. This, in combination with the contrasting permeability...

... Zone and constrain the timing of ore formation. Apatite fission track ages range from 203 to 241 Ma, with typical uncertainties of ± 10 Ma. Mean confined track lengths generally vary between 12.0 and 13.4 μm and indicate that the apatites record "apparent" ages only. An inferred thermal history...

Once downloaded, the data are prepared in .csv format, validated and matched to the individual node. Fig...

...Huichuan Liu; Sune G. Nielsen; Guangyou Zhu Abstract Slab material transfer processes in continental arcs can be challenging to decipher because magmas are often characterized by significant contributions from continental material. In this study, we identified a Prototethyan continental arc (419...

...Sune G. Nielsen Abstract The Earth's mantle is divided into separate reservoirs. From basaltic lavas erupted today we know that the upper mantle is depleted in incompatible trace elements, whereas ocean island basalts (OIB) sample a deep, more enriched reservoir. The two incompatible elements...

To date, Mg isotopic data have been reported for only six cratonic eclogites from...

The analysis indicates that the depositional environment of the target lower part of the Ganchaigou Formation is an alluvial fan. We define eight lithofacies according to the core analysis and five sedimentary...

..., is the Suning Formation, the lithology of which consists of alternations of brown clay and dark gray clay. The dark gray or black carbonaceous clay was probably deposited in a marsh. Between the gray or black clay, sand and gravel with parallel and tabular cross-bedding were deposited, indicating that this may...

... ( Lachaal et al. 2016 ). This interesting aquifer strategy is represented by Lower Miocene and Oligocene sandstones ( Ben Salem 1992 ; Ben Salem and Taamallah 1995 ). The Oligocene formations crop out on the southwestern border of the Jebel Abderrahman anticline. This element can play an important role...
