Abstract Geophysical exploration techniques play a pivotal role in enhancing the accuracy of mineral prospecting predictions. However, relying solely on individual methods often introduces uncertainties. This study presents case from Yongxin gold deposit, where we integrated audio-frequency magnetotelluric (AMT) with gravimetric surveying and high-resolution magnetic profiling to overcome this challenge. Advanced three-dimensional modeling were utilized precisely delineate lithological...
Abstract Rb, Sr, and magnetic susceptibility have been measured in the last interglacial–glacial loess profiles at Luochuan Huanxian, central China. A high degree of similarity between parameters both suggests that variations Rb/Sr ratios sequence can be regarded as an indicator East Asian summer monsoon strength. Matching record with SPECMAP δ 18 O curve ratio responds sensitively to changes induced by global ice-volume variation.
A 180‐m‐thick loess‐paleosol sequence from the northwestern Chinese Loess Plateau was investigated to construct a high‐resolution record of East Asian monsoon variability over last seven glacial‐interglacial cycles. The low‐field magnetic susceptibility ( χ , mass‐specific) and mean grain size are used as proxies for changes in intensity summer winter monsoon, respectively. Because weaker pedogenesis at compared central Plateau, our records show muted contrast but an enhanced monsoon....
Eolian dust deposits in north China provide an excellent means of determining past variations continental paleoclimate and atmospheric circulation. However, debate still exists on which deserts east Asia are the dominant sources Chinese loess whether provenance has shifted significantly at different time scales. Here we present new constraints fine‐grained deposited central Loess Plateau (CLP) by combining electron spin resonance signal intensity crystallinity index quartz contained samples...

Significance Selective inhibition of the intrinsic coagulation pathway is a promising strategy for developing safer anticoagulants without serious bleeding consequences. We prepared and identified series oligosaccharides as inhibitors tenase, which final rate-limiting enzyme complex in an attractive but less explored target due to lack pure selective inhibitor. Analysis these purified reveals precise structure fucosylated glycosaminoglycan. Among oligosaccharides, nonasaccharide minimum...
Abstract The Permian marine-terrestrial system of the North China block provides an exceptional window into evolution northern temperate ecosystems during critical transition from icehouse to greenhouse following late Paleozoic ice age (LPIA). Despite many studies on its rich hydrocarbon reserves and climate-sensitive fossil flora, uncertain temporal constraints correlations have hampered a thorough understanding records geologic, biologic, climatic change block. We present new...
Top-down cascade effects are among the most important mechanisms underlying community structure and abundance dynamics in aquatic terrestrial ecosystems worldwide. A current challenge is understanding factors controlling trophic strength under global environmental changes. Here, we synthesized 161 sites to analyze how multiple influence consumer-resource interactions with fish freshwater ecosystems. Fish have a profound negative effect on zooplankton water clarity but positive primary...
Abstract We examined the top 135 m, that is, entire Pleistocene, of classic Luochuan section on Chinese Loess Plateau with a diffuse reflectance spectrophotometer from near ultraviolet, through visible, and into infrared. From data we calculated sample brightness which, some caveats, is reasonable proxy for magnetic susceptibility. Mineralogic changes were identified by factor analyzing first derivative percent examining samples high scores. Two factors which explain about 96% cumulative...
