Geological Journal, EarlyView.This study reveals that the underexplored Benin Basin features a narrow shelf and steep slope, which promoted the development of multi‐phase, stacked channel‐lobe complexes. These gravity flow deposits, further enhanced by bottom current reworking, reveal a significant undiscovered Upper Cretaceous stratigraphic play with considerable petroleum ...

Geological Journal, EarlyView.The rhyolitic ignimbrite and K‐feldspar granite porphyry from the Wangmushan mining district, northern Fujian yield ages of 173.8 ± 0.8 and 102.6 ± 0.4 Ma, respectively. Geochemical data, zircon trace elements, whole‐rock Sr–Nd–Pb isotope data, and zircon Hf isotopic compositions indicate that the rhyolitic ignimbrite originated from partial remelting ...

River Research and Applications, EarlyView.ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Sustainable Development, EarlyView.ABSTRACT Colorado's geologic, pedologic, topographic, hydrological, and climatic contrasts create strong but under‐synthesized opportunities for sustainable agritourism. This review investigates how geodiversity, and the broader environmental heterogeneity within which it operates, can be used to diversify farm income, strengthen place‐based visitor ...

Геодинамика и тектонофизика, 2016 Paradoxically, the lists of “proxies” of both plate- and plume-related settings are devoid of even a mention of the high-grade metamorphic rocks (granulite, amphibolite and high-temperature eclogite facies).

Microplate Tectonics Through Earth History and Across Solid Multispheres
Geological Society of China Bulletin, EarlyView.The evolution of tectonic microplates throughout Earth´s history as well as the transitions between microplates across different solid spheres offers a novel approach to expanding the traditional plate tectonics theory. ABSTRACT The evolution of tectonic microplates throughout Earth's history as well as the transitions between microplates across ...

Journal of Fish Biology, EarlyView.Abstract Distinguishing fish populations is a long‐standing challenge in fisheries management, and otolith shape provides a low‐cost marker of population structure. Fish size strongly influences otolith shape; however, within‐lake size variation can obscure differences among populations. Here, a within‐lake length adjustment of otolith elliptic Fourier

Sr-Nd isotope geochemistry of the early Precambrian sub-alkaline mafic igneous rocks from the southern Bastar craton, Central India [PDF]
, 2009 Sr–Nd isotope data are reported for the early Precambrian sub-alkaline mafic igneous rocks of the southern Bastar craton, central India. These mafic rocks are mostly dykes but there are a few volcanic exposures.
