Long-standing debates exist over the timing and mechanism of uplift of the Tibetan Plateau and, more specifically, over the connection between lithospheric evolution and surface expressions of plateau uplift and volcanism. Here we show a T-shaped high wave speed structure in our new tomographic model beneath South-Central Tibet, interpreted as an upper-mantle remnant from earlier lithospheric f...

The accessory mineral assemblage (AMA) of igneous cumulate xenoliths in volcanoclastic deposits and lava flows the Carpathian back-arc basin testifies to composition intrusive complexes sampled by Upper Miocene-Pliocene basalt volcanoes. magmatic reservoir beneath Pinciná maar is composed gabbro, moderately alkalic alkali-calcic syenite, calcic orthopyroxene granite (pincinite). complex wider a...

ABSTRACT Yellow passion fruit is a species widely cultivated throughout the Brazilian semi-arid territory, but its yield affected by quality of waters this region. In context, objective was to evaluate gas exchange and production cv. BRS Rubi do Cerrado irrigated with different cationic natures. The study conducted in drainage lysimeters under greenhouse conditions Campina Grande, PB, Brazil, r...

The Pulang porphyry copper deposit (PCD), one of the main potential areas for resource exploration in China, exhibits typical alteration zoning. However, further investigation indicative significance minerals, additional insight into metallogenic characteristics, and prospecting guidelines continue to be challenging. In this study, ASTER WorldView-3 data were used map hydrothermal minerals by e...

The present study was performed for the ecotoxicity assessment of bismuth (Bi) effect on biological indicators soil condition: total number bacteria, catalase activity, dehydrogenases activity and germination Radish seeds length roots. Three types with significantly different resistance ability to heavy metal pollution were studied: Haplic Chernozems Calcic, Arenosols Eutric Cambisols Eutric.So...

soils of the arid–semiarid karaj basin in north-central iran have formed on alluvium-colluvium derived from mixed calcareous-gypsiferous marls of miocene and basic igneous rocks of holocene age. in order to characterize and classify the soils and to determine the soil-landscape relationship in the area, sixteen pedons located on different physiographic positions have been described, sampled and...
