Abstract China has unique salt lake resources, and they are distributed in the east of Eurasian subzone Northern Hemisphere Salt Lake Zone, mainly concentrated regions with modern mean annual precipitation lower than 500 mm. This paper preliminarily reviews progress made research for past 60 years. In Paleoclimate paleoenvironment from sediments, a series salts have been proposed to be indicators paleoclimate, well accepted by scholars. The chloride‐sulfate depositional west Qaidam Tarim...
Quantitatively assessing the porewater dissolved inorganic carbon (DIC) cycling in methane-enriched marine sediments is crucial to understanding contributions of different sources global pool. In this study, Makran accretionary wedge was divided into Zone 1 (high methane flux area) and 2 (background area). Porewater geochemical compositions (Cl – , SO 4 2– NH + Mg 2+ Ca Ba DIC δ 13 C-DIC) a reaction-transport model were used determine source calculate through carbonate precipitation...
Accurate knowledge of the relationship between modern vegetation and corresponding surface pollen assemblages is key to quantitative reconstruction paleovegetation paleoclimate. The steppe regions are affected by many factors distinguishing different plant community types, especially Artemisia Poaceae communities a major difficulty in studies these regions. In this study we used RDA analysis analyze percentage data from 119 sampling sites Bashang region North China, which has typical...
Mantle plumes originating from the Core-Mantle Boundary (CMB) or Transition Zone (MTZ) play an important role in material transfer through Earth's interior. The hotspot-related originate different mechanisms and have diverse processes of transfer. Both Morganian large low shear wave velocity provinces (LLSVPs) are derived D″ layer CMB, whereas Andersonian upper mantle. All a plume head at Moho, although LLSVPs additional MTZ. We compare geochemical characteristics various attempt to evaluate...
Abstract: The general classification of intermediate‐acid intrusive rocks in the metamorphic zone Gaoligong Mountains as one terranes Proterozoic is problematic regarding intrusion stage and age, well subsequent metamorphism deformation. In this study, we investigated granitic gneiss based on 1:50,000 regional geological survey Qushi Street (2011–2013) SHRIMP U‐Pb zircon geochronology. Results showed that dating ranged from 163.5±5.7 Ma to 74.0±2.0 Ma. Thus, was grouped into orthometamorphic...
A good graphical user interface (GUI) is crucial for an application's usability, so vendors and regulatory agencies increasingly place restrictions on how GUI elements should appear to interact with users. Motivated by this concern, paper presents a new technique (based static analysis) checking conformance between (Android) applications policies expressed in formal specification language. In particular, (1) describes language formalizing policies, (2) proposes program abstraction called...
A new method of fault location distribution network based on the tree structure diagram and improved Dempster-Shafer Theory evidence is proposed to solve problem misjudgment caused by abnormal information in network. Firstly, this paper presents a search diagram. Through diagram, we can ensure initial positioning result respectively three different alarm information. The include indicator information, transformer trouble calls. And then, through using evidence, integrate results get final...
The Banshan archaeological site is one of the most important Early Pleistocene Paleolithic sites in Nihewan Basin North China. Based on analyses pollen, grain size and charcoal 56 samples from a sedimentary profile, we reconstructed environment before after interval hominin activity (1.340–1.290 Ma). results show that appearance (1.340–1.324 Ma), climate region was initially cold wet then dry. regional vegetation mainly Pinus Picea forest earlier stage, steppe dominated by arid-tolerant...
