2010, 16(4): 325-339.
Abstract (546) HTML (204) PDF (2038KB)(26)
Abstract:
The Aktogai ore field consists of a group of porphyry Cu-Mo-Au deposits, such as Aktogai, Aidarly, and Kyzylkia deposits, in the Balkhash Metallogenic Belt of the Central Asian Metallogenic Domain. They are formed in the Balkhash volcanic arc of the north-central margin of Kazakhstan Orocline due to...
GEOLOGICAL CHARACTERISTICS AND METALLOGENIC AGE OF BORLY PORPHYRY CU DEPOSITS IN BALKHASH METALLOGENIC BELT, KAZAKHSTAN
ZHAO Hengle, CHEN Xuanhua, QU Wenjun, YANG Yi, LI Xuezhi, YANG Nong, CHEN Zhengle, HAN Shuqin
2010, 16(4): 340-348.
Abstract (535) HTML (309) PDF (806KB)(26)
Abstract:
The Balkhash Metallogenic Belt in Kazakhstan, with the output of many large and superlarge porphyry Cu-Mo deposits and some quartz-vein greisen W-Mo deposits, is a very famous porphyritic Cu-Mo metallogenic belt in Central Asian Metallogenic domain. In this paper, the geological characteristics of t...
GEOLOGICAL CHARACTERISTICS AND RE-OS ISOTOPIC DATING OF AKSHATAU GREISEN-TYPE W-MO DEPOSIT IN BALKHASH METALLOGENIC BELT
LI Yong, CHEN Xuanhua, QU Wenjun, WANG Zhihong, YANG Nong, CHEN Zhengle, HAN Shuqin
2010, 16(4): 349-358.
Abstract (265) HTML (102) PDF (926KB)(9)
Abstract:
The Akshatau disseminated Be-W-Mo deposit is a large-scale greisen-type deposit in the Balkhash metallogenic belt of Central Asian Metallogenic Domain, with typical mineral compositions, wall rock alterations, ore body shapes, and ore texture and structures of greisen-type deposit. The ore field has...
TISSION-TRACK DATING FOR ACTIVITY OF THE LONGMENSHAN FAULT ZONE AND UPLIFTING OF THE WESTERN SICHUAN PLATEAU
YANG Nong, ZHANG Yueqiao
2010, 16(4): 359-371.
Abstract (346) HTML (163) PDF (770KB)(34)
Abstract:
Twelve samples of tectonites, metasediments and granites taken from the western Sichuan Plateau were dated in this study by apatite fission track dating method. The results are used to reconstruct uplifting history and fault activity of the Longmenshan tectonic belt in eastern margin of the Tibetan ...
MAGNETIC SUSCEPTIBILITY OF HEQING DRILL CORE AND ITS PALAEOENVIRONMENTAL IMPLICATIONS
XU Xinwen, QIANG Xiaoke, AN Zhisheng, LI Xubin, LI Peng, SUN Yufang
2010, 16(4): 372-382.
Abstract (371) HTML (175) PDF (666KB)(12)
Abstract:
Located in southwestern China, the Heqing Basin received continuous lacustrine sediments of great thickness, which could be an excellent continental record for Indian monsoon. In this study, we choose the lake sediments from Heqing drill core to analyze the paleoenvironmental significance of magneti...
GEOMORPHOLOGY OF THE FUXIANHU DRAINAGE BASIN AND ITS STRUCTURAL IMPLICATION
CHENG San-you, LI Ying-jie
2010, 16(4): 383-392.
Abstract (393) HTML (304) PDF (711KB)(22)
Abstract:
We took adavage of ArcGIS software platform to obtain the data of geometrical shapes and boundaries of 61 sublevel individual watersheds in the Fuxianhu drainage With SRTM-DEM as the basic data, 34 in the ridges east to Xiaojiang fault, 27 in the ridges west to the Xiaojiang fault. Afterwards, we ca...
PRETREATMENT METHODS FOR ANALYZING THE TOTAL ORGANIC CARBON AND NITROGEN CONTENTS OF HEQING CORE SEDIMENTS AND THEIR ENVIRONMENTAL SIGNIFICANCES
Lu Feng-yan, An Zhi-sheng
2010, 16(4): 393-401.
Abstract (205) HTML (122) PDF (555KB)(13)
Abstract:
Total organic carbon content (TOC), Total organic nitrogen content (TN) and their ration (C/N) of lacustrine sediments have been widely used in the Quaternary palaeoenvironment researches. Before measuring the TOC and TN of the sediments, the first important step is to effectively remove the inorgan...
QUANTITIVELY PARTITION OF EOLIAN AND HYDROMORPHIC COMPONENTS IN LACUSTRINE SEDIMENTS: AN EXAMPLE FROM LAKE QINGHAI

Abstract (242) HTML (115) PDF (663KB)(10)
Abstract:
This paper reports a cluster analysis on sources of Lake Qinghai sediments, and a grainsize analysis on the surface sediments of Lake Qinghai and its adjacent typical aeolian loess Based on the results, we have fitted the typical grain size distributions of the lake sediments and evaluated the propo...
PALAEOMAGNETIC STUDY OF THE LATE CENOZOIC STRATA IN THE CENTRAL TARIM BASIN:IMPLICATION ON THE EVOLUTION OF TAKELIMAKAN DESERT
