The Mineral Industry of China in 2012
2012 Minerals Yearbook CHINA U.S. Department of the Interior February 2015 U.S. Geological Survey THE MINERAL INDUSTRY OF CHINA By Pui-Kwan Tse China ranked second behind the United States as the world’s social welfare costs. The working-age population decreased by leading economic power; it was also one of the world’s 3.5 million in 2012. The labor force in the mining sector was leading mineral producing and consuming countries. In 2012, 6.11 million, or 4.2% of the country’s total workforce in 2011. China’s economy remained strong compared with most of the In the manufacturing sector, rising production and developed countries in the West. During the past two decades, environmental costs, overcapacity, and uncertain external China’s economic growth was the result of a combination demand were likely to affect the sector’s profit margin. of trade and investment, and this growth greatly affected the Month-on-month production growth in the ferrous metals sector global commodity market. The country’s demand for energy, decreased significantly to 19.1% in November from 23.2% metals, and minerals was particularly strong.

Quinn Li, Graduate School Representative ABSTRACT GEOMICROBIOLOGICAL STUDIES OF SALINE LAKES ON THE TIBETAN PLATEAU, NW CHINA: LINKING GEOLOGICAL AND MICROBIAL PROCESSES By Hongchen Jiang Lakes constitute an important part of the global ecosystem as habitats in these environments play an important role in biogeochemical cycles of life-essential elements. The cycles of carbon, nitrogen and sulfur in these ecosystems are intimately linked to global phenomena such as climate change. Microorganisms are at the base of the food chain in these environments and drive the cycling of carbon and nitrogen in water columns and the sediments. Despite many studies on microbial ecology of lake ecosystems, significant gaps exist in our knowledge of how microbial and geological processes interact with each other. In this dissertation, I have studied the ecology and biogeochemistry of lakes on the Tibetan Plateau, NW China. The Tibetan lakes are pristine and stable with multiple environmental gradients (among which are salinity, pH, and ammonia concentration). These characteristics allow an assessment of mutual interactions of microorganisms and geochemical conditions in these lakes. Two lakes were chosen for this project: Lake Chaka and Qinghai Lake. These two lakes have contrasting salinity and pH: slightly saline (12 g/L) and alkaline (9.3) for Qinghai Lake and hypersaline (325 g/L) but neutral pH (7.4) for Chaka Lake. -

Geomorphic and Chronometric Evidence for High Lake Level History in Gahai Lake and Toson Lake of Northeastern Qaidam Basin, Nort
JOURNAL OF QUATERNARY SCIENCE (2012) 27(8) 819–827 ISSN 0267-8179. DOI: 10.1002/jqs.2572 Geomorphic and chronometric evidence for high lake level history in Gahai Lake and Toson Lake of north-eastern Qaidam Basin, north-eastern Qinghai–Tibetan Plateau QISHUN FAN,1* HAIZHOU MA,1 GUANGCHAO CAO,2 ZONGYAN CHEN2 and SHENGKUI CAO2 1Luminescence Dating Group, Key Laboratory of Salt Lake Resources and Chemistry, Qinghai Institute of Salt Lakes, Chinese Academy of Sciences, Xining 810008, China 2School of Life and Geographic Science, Qinghai Normal University, Xining 810008, China Received 26 August 2011; Revised 25 June 2012; Accepted 6 July 2012 ABSTRACT: Palaeoshorelines, highstand lacustrine sediments and lakeshore terraces are preserved around saline lakes in the arid Qaidam Basin. Previous research indicates that the chronology of a mega-paleolake in the Qaidam Basin during the late Pleisotocene is controversial. Here we report quartz optically stimulated luminescence (OSL) age estimates of highstand lacustrine sediments, shoreline features and geomorphic exposures that contribute to a revision of the lake level history of Gahai and Toson lakes in the north-eastern Qaidam Basin, on the northeastern Qinghai– Tibetan Plateau (QTP) margin. The results imply that: (i) high lake levels at Gahai and Toson lakes based on quartz OSL dating occurred at 85–72, 63–55, 31, 5.4 and 0.9–0.7 ka, probably corresponding to periods of warm and wet climate; (ii) periods of high lake levels are almost synchronous with other lakes on the QTP (e.g. Qinghai and Namco lakes), with the highest late Pleistocene levels occurring during Marine Oxygen Isotope Stage 5; and (iii) highstand phases on the QTP are out of phase with those of low-latitude lakes in the southern hemisphere, possibly driven by solar insolation variability in the low-latitude region. -
