Study on the Crustal Stability in Three-Gorges Area of the Yangtze River

Li Ping,Li Yuanjun

Strategic Study of CAE 2004, Volume 6, Issue 6,   Pages 26-34

Abstract:

The Three-Gorges Dam on the Yangtze River is situated on the intact rock mass composed of diorite-granite at the southern termination of the Huangling block. The Huangling block as a sub-plate having double-layer structure (crystalline basement and sedimentary cover) in China continent keeps constant and slow uplifting as a whole since its formation in the Indosinian movement. Tectonic deformation within the block is not significant, with exception of a slight southeastward tilting. The block is confined by many active structures, of which the sub-longitudinal Yuan*an and Xiannushan deep fault zones are the main strongly seismogenic zones. The Yuan´an fault zone represents a regional boundary between West Henan, West Hubei and West Hunan mountainous regions as well as the Nanyang, Jianghan and Dongting Lake basins, with a total length of more than 1000 km. Two times M 6.5 earthquakes (the Changde and the Nanyang earthquakes) had occurred in the fault zone in historic time and the distance between the two epicenters is about 500 km. The Xiannushan fault one extends along the Xiangxi River northward and ends at the Qingfeng fault. It runs southward across Yuyangguan Pass and then its trace is unknown. Total length of the fault zone is more than 220 km. The fault zone has tectonic condition for occurrence of M 6 earthquake. The possible seismic risk for the dam may come from these two strong seismogenic zones, thus the seismic intensity influencing the dam was estimated to be 6°〜7° and the horizontal peak acceleration to be 0.1〜0.15 g.

A full-scale integrated-bioreactor with two zones treating odours from sludge thickening tank and dewatering

Jianwei Liu, Kaixiong Yang, Lin Li, Jingying Zhang

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 4, doi: 10.1007/s11783-017-0932-8

Abstract: A full-scale integrated-bioreactor consisting of a suspended zone and an immobilized zone was employed to treat the ordours emitted from a wastewater treatment plant. The inlet concentrations of H S and NH were 1.6–38.6 mg·m and 0.1–6.7 mg·m , respectively, while the steady-state outlet concentrations were reduced to 0–2.8 mg·m for H S and 0–0.5 mg·m for NH . Both H S and NH were eliminated effectively by the integrated bioreactor. The removal efficiencies of H S and NH differed between the two zones. Four species of microorganisms related to the degradation of H S and NH were isolated. The characteristics and distributions of the microbes in the bioreactor depended on the inlet concentration of substrates and the micro-environmental conditions in the individual zones. Product analysis indicated that most of the H S was oxidized into sulfate in the immobilized zone but was dissolved into the liquid phase in the suspended zone. A large amount of NH was converted into nitrate and nitrite by nitration in the suspended zone, whereas only a small amount of NH was transferred to the aqueous phase mainly by absorption or chemical neutralization in the immobilized zone. Different microbial populations dominated the individual zones, and the major biodegradation products varied accordingly.

A comparison of geology geochemical characteristics between the Kalatongke and the Jinchuan Cu-Ni sulfide deposit and its significance

Dai Junfeng,Gong Lei and Fan Lifei, Wang Yong, Zhao Binbin

Strategic Study of CAE 2015, Volume 17, Issue 2,   Pages 85-96

Abstract:

According to the analysis and comparison with the content and geochemical characteristics of and trace element from Cu-Ni sulfide deposits between Kelatongke and Jinchuan, meanwhile, combing different tectonic setting and rock series of these two types of deposits, we study their magmatic and mineralization processes. The results show that major element of Kalatongke belongs to the tholeiitic basalt system; incompatible trace element presents as enrichment of large ion lithophile elemen(LILE) and depletion of high field strength element(HFSE), suggesting that they are derived from the continental crust; the rare earth element (REE) presenting rich in light rare earth element (LREE), and there is no obvious Eu anomalies, Sr and Nd isotopes indicates that the magma source is depleted asthenosphere mantle. Major element of Jinchuan deposit belongs to the tholeiitic basalts and mid ocean ridge basalt system; incompatible trace element presents as enrichment of LILE, depletion of HFSE, showing the magma suffers from contamination of crust materials or there are materials of subducted oceanic crust in the source ; the ratio of N(La)/N(Nb) and N(Zr)/N(Nb) indicating its source is derived from EMI mantle; the REE presenting enriched in LREE, the ratio of N(La)/N(Yb), N(La)/N(Sm) and N(Gd)/N(Yb) presenting enriched in LREE; and there is no obvious Eu anomalies, Sr and Nd isotopes declaring magma derived from enriched mantle. And we also predicted the magma conduit and mineralization potential of two ore deposits by 3D geological modeling, hoped it will useful for later period exploration.
