The Jiadi gold deposit, situated in the Southwestern region of Guizhou, is a large-scale, recently discovered, basalt-hosted, and fine-grained disseminated deposit. This study has unveiled that tectonic deformation deposit can be categorized into four stages: Late Paleozoic crustal uplift brittle (D1-deformation) stage; Early Yanshanian NW-trending compressive ductile (D2-deformation) NS-trendi...

We studied the mineralization and sulfur isotopic composition of sulfides gold–palladium ores in olivine clinopyroxenites from Dzelyatyshor massif made up a continuous layered series rocks: olivine-free clinopyroxenite–olivine clinopyroxenite–wehrlite. The primary igneous layering rocks, manifested as different quantitative ratios clinopyroxene them, controls local trends variability chemistry ...

Intact soil cores from three adjacent sites (Site A: grazed, Site B: fenced for 4 years, and Site C: fenced for 24 years) were incubated in the laboratory to examine effects of temperature, soil moisture, and their interactions on net nitrification and N mineralization rates in the Inner Mongolia grassland of Northern China. Incubation temperature significantly influenced net nitrification and ...
