The phyllic alteration in a number of circum-Pacific porphyry Cu-Au deposits is related to high-temperature saline magmatic fluids. This contradicts the widely used genetic models wherein phyllic alteration formed as the result of mixing between magmatic and meteoric fluids. At the Endeavour 26 North porphyry deposit in eastern Australia, the transition from early potassic to the main-stage phy...

An integrated study involving whole-rock and Sr–Nd–Hf isotope geochemistry and zircon geochronology and trace element combined with detailed field investigation was carried out for the composite Meiwu batholith in the West Qinling orogenic belt of central China to probe the origins of its compositional diversity and its emplacement history. The batholith is composed of quartz diorite, granodior...

Permian granitoids have been identified in the Zhalageamu district, Inner Mongolia, NE China, which provide an excellent opportunity to constrain tectonic evolution of Central Asian Orogenic Belt (CAOB). In this study, we determined zircon U Pb ages quartz diorite, granodiorite porphyry, diorite porphyry and granite at Zhalageamu. These are 269.5 ± 1.8, 261.4 1.9, 256.4 2.0 255.2 Ma, respective...

Fifteen volumes long, Against the Christians was written by the Roman pagan Porphyry circa 280 and was an educated man's studied attack on Christian theology. An exceedingly powerful and successful work, it and commentaries on it were condemned by the imperial church in 448 and burned. Only remnants which were contained in books that were primarily about other matters have survived until the pr...

Phytolith-occluded carbon (PhytOC) is a stable carbon (C) fraction that has effects on long-term global C balance. Here, we report the phytolith and PhytOC accumulation in moso bamboo leaves developed on four types of parent materials. The results show that PhytOC content of moso bamboo varies with parent material in the order of granodiorite (2.0 g kg(-1)) > granite (1.6 g kg(-1)) > basalt (1....

A large anatectic complex of Hercynian age, the Peña Negra complex, crops out in the central-north area of the Sierra de Gredos, Avila batholith, central Spain. Migmatites and anatectic granitic rocks were generated during the Upper Carboniferous from a Neoproterozoic – Lower Cambrian schist–greywacke complex with minor interlayered orthogneisses. Granitic rocks appear as subhorizontal sheets o...

[1] Many geomorphic studies assume that bedrock geology is not a first-order control on landscape form in order to isolate drivers of geomorphic change (e.g., climate or tectonics). Yet underlying geology may influence the efficacy of soil production and sediment transport on hillslopes. We performed quantitative analysis of LiDAR digital terrain models to examine the topographic form of hillsl...
