Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Boron availability and fertilizer response of maize in soils from sub‐Saharan Africa

Journal of Plant Nutrition and Soil Science, EarlyView.
Abstract Background and aims Low boron (B) availability is associated with strongly weathered, coarse‐textured, and low organic matter soils, widespread in sub‐Saharan Africa (SSA). It is unknown to what extent B fertilization can increase maize yields in SSA.

Legacy Knowledge on Landscape Soil Carbon—Concentrated Organic Input to Selected Sites Comes With the Expense of Soil Health of Larger Areas

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Xu et al. show that high organic input and N‐balancing fertilization improve soil health at the soil plot scale; however, the effects of allocating C and N on soil health at the landscape or region scale are not considered. Historical soil management systems show that such a depletive redistribution leads to local agricultural improvements ...

Geochronology of the Whittlesey sedimentary succession, eastern England: The ‘Pompeii’ of the British late Middle Pleistocene to Holocene record

Journal of Quaternary Science, EarlyView.
Abstract The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...
