Environmental baseline evaluation of lead in shallow groundwater based on statistical and spatial outlier identification
Springer Science and Business Media LLC - Tập 34 - Trang 416-421 - 2015
Linhua Sun
A series of methods have been applied for evaluating the environmental baseline—especially on a regional scale—because of its importance for local environmental management. However, most of the methods have been statistical in nature, and spatial variability has not been considered simultaneously. In this study, the combined use of statistical and spatial methods has been carried out to analyse le...... hiện toàn bộ
A study on A-type granites in Suzhou, China
Springer Science and Business Media LLC - Tập 7 - Trang 29-45 - 1988
Zhang Xinglong, Wang Jiabing, Shen Bochun
The Suzhou granite suite is the anorogenic product, which is located on the inactive continental margin of east China. It was emplaced about 141 Ma ago, occurring as a stock with a polygonal outline on the surface, belonging to alkali potash-feldspar granites with K2O > Na2O, Reit’s alkali coefficient = 0.694, SiO2 = 74.95, and Al2O3/(K2O + Na2O)mol= 1. Besides K and Na, Li and Rb are also rather ...... hiện toàn bộ
Geochronology of and Nd-Sr-Pb isotopic evidence for mantle source in the ancient subduction zone beneath Sanshui Basin, Guangdong Province, China
Springer Science and Business Media LLC - - 1989
Zhu Bingquan, Wang HuiFen, Mao Cunxiao, Zhu Nai Juan, Huang Rongsheng, Peng Jianhua, Pu Zhiping
The available petrochemical data indicate that volcanic rocks in the Sanshui basin of Guangdong Province are characteristic of the island-arc tholeiite-calc-alkaline series.Their K-Ar ages range from 43 to 64 Ma, corresponding to Early Tertiary. The Nd-Sr-Pb isotopic correlations give two binary mixing trends, indicating a mixed source of Leiqiong depleted mantle, seawater and altered sediments pe...... hiện toàn bộ
A new type of micro-disseminated gold deposits in association with diabase found in Yunnan and Guizhou provinces and Guangxi Zhuang Autonomous Region—Their geological characteristics and metallogenic conditions
Springer Science and Business Media LLC - Tập 31 - Trang 449-456 - 2012
Zhuyun Li, Tianlong Lan, Ruide Ran, Guofan Cheng
With the continuous development of gold ore prospecting and exploration in recent years a new type of micro-disseminated gold deposits have been found in the regions of Southwest Guizhou Province and Northwest Guangxi Zhuang Autonomous Region, with the orebodies directly occurring in diabase or in the contact zone between diabase and strata. The orebodies are strictly controlled by fault structure...... hiện toàn bộ
New data on geochemistry
Springer Science and Business Media LLC - Tập 5 - Trang 34-54 - 1986
Zhengzhang Tao
Described in the present paper is the evolution of the concept of “clarke” introduced by A. E. Fersman. Based on the data available in literature, the atomic clarkes of chemical elements in the earth’s crust were computed and the logarithmic distribution curves were drawn by means of the micro-computer (PC-1500). Volume percentages of the chemical elements in the orust were also computd and the le...... hiện toàn bộ
Assessing and reducing risks from historical gold mine tailings in Nova Scotia, Canada

Springer Science and Business Media LLC - Tập 25 - Trang 20-20 - 2006
Celine S. L. Lee, Shihua Qi, Gan Zhang, Xiangdong Li
Characteristics of biomarker in source rocks of Linxi Formation in Taohaiyingzi region, Zhalute basin
Springer Science and Business Media LLC - Tập 34 - Trang 338-345 - 2015
Li Liu, You-jun Tang, Xing-chao Jiang
Based on gas chromatography and gas chromatography mass spectrometry techniques, the authors researched biomarker characteristics of the Linxi Formation source rocks in the area of Taohaiyingzi, and analyzed the information and petroleum geological significance that were indicated by source of organic matter, sedimentary environment, maturity and so on. Gas chromatography peak of saturated hydroca...... hiện toàn bộ
Atomic emission determination of microelemental composition of diatoms
Springer Science and Business Media LLC - Tập 25 - Trang 201-202 - 2006
Irina E. Vasilyeva, Elena V. Shabanova, Natalia N. Pakhomova, Ekaterina N. Epova
Study of the factors affecting the abundance of organic matter in Jurassic carbonate rocks in Qiangtang Basin, Tibet
Springer Science and Business Media LLC - Tập 23 - Trang 52-56 - 2004
Wen Zhigang, Hu Mingyi, Gong Wenping, Xiao Chuantao
Field and laboratory analyses of carbonate rock samples from the Qiangtang Basin, Tibet, indicate that carbonate source rocks are mainly developed in the Middle Jurassic Xiali Formation and Upper Jurassic Suowa Formation. Comprehensive studies showed that the Suowa Formation carbonate source rocks have a favorable hydrocarbon-generating potential. The abundance of organic matter in the carbonate r...... hiện toàn bộ
