Therefore, it has become imperative to search for Li from other sources. Li in coal is thought to be one of the candidates. In this study, the petrology, mineralogy, and geochemistry of No. 21 coal from the Hebi No. 6 mine, Anhe Coalfield, China, was reported, with an emphasis on the distribution, modes of occurrence, and origin of Li. The results show that Li is enriched in the No. 21 coal, and its concentration coefficient (CC) value is 6.6 on average in comparison with common world coals. -

Huang) cCollege of Resources and Environment, University of Chinese Academy of Sciences, Beijing 100049, China dBeijing National Day School, Beijing 100039, China Received 22 October 2018; Accepted 21 January 2019 abstract The cryosphere water resource service (CWRS) is the most significant cryosphere service (CS) to directly affect human societies. Regionalization of CWRS is an important prototype for the comprehensive regionalization of CSs. It is also a crucial cutting-edge exploration of interdisciplinary work across cryospheric science, physical geography and human geography. We constructed a quan- titative indexing system for the regionalization of CWRS along the dimensions of base–supply– demand informed by the characteristics of cryosphere resources and human use of CSs. Different levels of regionalization are subdivided using cluster analysis, the importance index of CWRS, and a location entropy model. A region in Northwest China with significant CWRS use was the study area. From the joint effects of nature and human activity, there emerge principles of regional differentia- tion that govern the regionalization of CWRS. The study area was first divided into three high level service regions according to the availability of stored cryosphere water in snow cover, frozen ground and glaciers, indicating the regulatory function of cryosphere components. -

The UHP rocks, as lentoid bodies in regional gneisses, include eclogite (garnet-bearing pyroxenite), garnet peridotite and various pelitic or felsic gneisses. There are many re- cords of minerals and microstructures of exsolution indicate the UHP metamorphism, such as coesite (or its pseudomorph), diamond, exsolution of clinopyroxene/amphibole/+rutile or rutile+quartz+apatite in garnet, exsolution of quartz in omphacite and exsolution of kyanite+spinel in precursor stishovite.

High-resolution sedimentary records can help us to assess how erosion and weathering have evolved in response to recent climatic and anthropogenic disturbances. Here we present data from a high- resolution (∼75 cm/k.y.) sedimentary archive from the South China Sea. Provenance data indicate that the sediment was derived from the Red River, and can be used to reconstruct the erosion and/or weathering history in this river basin. -

The Thickness and Structural Characteristics of the Crust Across Tibetan Plateau from Active-Sources Seismic Profiles∗
Earthq Sci (2009)22: 21−31 21 Doi: 10.1007/s11589-009-0021-6 The thickness and structural characteristics of the crust across Tibetan plateau from ∗ active-sources seismic profiles Qiusheng Li 1,2, Rui Gao 1,2 Zhanwu Lu 1,2 Ye Guan 1,2 Jisheng Zhang 1,2 Pengwu Li 1,2 Haiyan Wang 1,2 Rizheng He 1,2 and Marianne Karplus3 1 Lithosphere Research Center, Institute of Geology, Chinese Academy of Geology Science,Beijing 100037, China 2 Earthprobe and Geodynamics Open Laboratory of Chinese Academy of Geology Science, Beijing 100037, China 3 Crustal Geophysics Group, Stanford University, Stanford CA 94305, USA Abstract The Tibetan plateau as one of the youngest orogen on the Earth was considered as the result of conti- nent-continent collision between the Eurasian and Indian plates. The thickness and structure of the crust beneath Tibetan pla- teau is essential to understand deformation behavior of the plateau. Active-source seismic profiling is most available geo- physical method for imaging the structure of the continental crust. The results from more than 25 active-sources seismic pro- files carried out in the past twenty years were reviewed in this article. A preliminary cross crustal pattern of the Tibetan Pla- teau was presented and discussed. The Moho discontinuity buries at the range of 60−80 km on average and have steep ramps located roughly beneath the sutures that are compatible with the successive stacking/accretion of the former Cenozoic blocks northeastward. The deepest Moho (near 80 km) appears closely near IYS and the crustal scale thrust system beneath southern margin of Tibetan plateau suggests strong dependence on collision and non-distributed deformation there. -

Influence of Climate Change on Desertification in Qaidam Basin Huang Jingtao1,A, Jiang Yingxiang1,B 1Kunming University of Science and Technology Kunming China
Advances in Engineering Research (AER), volume 135 2nd International Conference on Civil, Transportation and Environmental Engineering (ICCTE 2017) Influence of climate change on Desertification in Qaidam Basin Huang Jingtao1,a, Jiang yingxiang1,b 1Kunming University of Science and Technology Kunming China [email protected],[email protected] Keywords:Precipitation;desertification;Basin Abstract. In this paper, the data of soil erosion from Mangya, Lenghu, Xiaowouhuo, Golmud, Ulan and Da six Dan Chai ecological monitoring stations monitoring data ranged from 2005 to 2015, and MODIS and GIMMS remote sensing monitoring NDVI values from 1985 to 2015. This thesis researched characteristics of the soil erosion in the Qaidam Basin. At this time, The author researched Qaidam Basin Erosion (block) and dune movement characteristics, as well as the changes of the precipitation and desertification area. The impact of climate change on Desertification in Qaidam Basin was analyzed. The result indicated that evaporation volume paralleled with desertification. Introduction Desertification refers to the land degradation in arid, semi arid and sub-humid arid regions caused by various factors, including climate variability and human activities [1-3]. Desertification is the third major environmental problem in the world. Also, it is one of the most prominent ecological problems in China, and seriously harms the sustainable development of Chinese desertification areas [4-6]. Qaidam Basin is one of the areas suffering the most serious desertification in China, and the ecological environment there is quite fragile. With the progress of the western basin and the increase of population in the basin area, the contradictions between construction and development, population and land, and resources development and environmental protection have appeared in front of people to different degrees. -
