Unconformity-like Reflection Pattern under the Moho in the Sulu Area

Continental Dynamics 1997年第1期 22-28页

作者： YANG Wencai (institute of Geology, Chinese academy of Geological {2. (CAGS), Beijing 100037,china)

When seismic exploration is carried out for finding oil/gas traps in a sedimentary basin, angular unconformity-like reflectors often appear in a seismic profile, indicating some promising structures such as pinchout. People usually think that the angular unconformity-like reflection pattern could occur only in a sedimentary basin within the upper crust because the pattern corresponds to a combination of a flat layer and some dipping layers, and they belong to different sedimentary sequences. In order to find optimal site for continental scientific drilling in the Dabie-Sulu ultra-high pressure metamorphic belt containing minerals such as coesite and micro-diamond, I have been in charge of geophysical investigations in these Proterozoic metamorphic ter- ranes of crystalline rocks. The investigation includes deep seismic reflection, magnetotelluric survey, gravity and magnetic studies, together with large-scale geological mapping on the surface. In the Shimen site located in southeast Shandong Province, East china, I have found a very clear angular reflection pattern, similar to those obtained by petroleum seismic exploration in sedimentary basins, appearing from 10.3 s to 13 s, right under the Moho discontinuity. This unusual and strange event from the uppermost mantle seems significant and might provide some clues for understanding the interaction between the crust and the mantle. Therefore I present the result here for further studies and worldwide comparison. I shall start with the basic geological settings of this area, then deal with the data acquisition and processing parameters as well as the deep seismic reflection sections to identify the deep angular unconformity-like pattern (see Fig. 4), finally, a brief discussion on interpretation of this type of reflection events.

GRANITOIDS IN YUEXI OF EASTERN DABIE MOUNTAIN, china

Scientia Geologica Sinica 1998年第4期 551-557页

作者： Jin Chengwei and Zheng Xiangsheng (institute of Geology Chinese academy of {2., Beijing 10002., china)

A lot of acid intrusions occur in Yuexi and are intruded in the North Dabie metamorphic Complex. Theycomprise monzo granite-syen ogranlie, granodion ie -quartz monzo di on ie and alkali granit e. Petrographi caland geochemical study of them indicates they were formed in the post-orogenic regimes. It is worthy tomention that an undeformed body ofgranodiorite-quartz monzodiorite is metaluminous (A/CNK, 0.8-0.9)and exhibits a smaller Eu anomaly (Eu/Sm 0.31). All granitoids in Yuexi district have early Cretaceousages of emplacement and negative εNd(0) (- 17 -2.). They are plotted as a horizontal zone on εNd,(0)- εSr(0)diagram, indicating these granitoids may be derived from a older earth crust.

Numerical Simulation of Pollutant Transport and Accumulation Areas in the Hangzhou Bay

引用

Transactions of Tianjin University 2009年第6期15卷 400-407页

作者：李宁毛志华张庆河 School of Civil Engineering Tianjin University State Key Laboratory of Satellite Ocean Environment Dynamics The Second Institute of Oceanography State Oceanic Administration

Based on the COHERENS model (a coupled hydrodynamic ecological model for regional and shelf seas), a numerical hydrodynamic model of the Hangzhou Bay, influenced by tide, regional winds and freshwater from the Yangtze River and the Qiantangjiang River was established. The Lagrangian particle tracking was simulated to provide tracer trajectories. For convenience, the modeling area was divided into 8 subdomains and the modeling focused on March (dry season) and July (wet season). Numerical simulation and analysis indicate that the tracer trajectories originated in different subdomains are quite different. Most particles released in the mouth of the bay move outside the bay quickly and reach the farthest place at 12..5°E; while particles released in the inner part of the bay mostly remain in the same subdomain, with only minor migrations in two opposite directions along the shore. The tracer experiments also indicate that the northwest region of the bay is an area where pollutant can easily accumulate in both wet and dry seasons, and that the southeast region of the bay is another area for pollutant to accumulate in dry season because it is the main path for the contaminant.

Rheological Simulating Study of Mechanical Conditions for Syn-extensional Basin and Mountain Coupling System

引用

Journal of china University of Geosciences 2003年第4期14卷 330-338页

作者： Wu Hongling Yin Xiulan institute of Geomechanics, Chinese academy of Geological {2., Beijing 100081 institute of Geomechanics Chinese Academy of Geological Sciences Beijing 100081

This article gives a mechanical model, in which the layers of lithosphere are assumed to be the creep materials, to study the coupling mechanism of a syn-basin-mountain system quantitatively by using the numerical simulating method. A geological dynamic extensional mode given by some geologists is theoretically discussed and verified. The study shows that lithosphere thickening or thinning is closely related to the thermal activity, or in other words, thermal convection beneath the lithosphere. It is one of the important factors affecting the formation of the basin-mountain coupling system. As an essential condition, only the upward buoyant force and the horizontal dragging force caused by the thermal convection jointly act on the bottom of the lithosphere, the stress and strain states in rock's layers are advantageous to forming the tectonic-landforms of the basin-mountain coupling system. A study on the creep features of the lithosphere shows that the stress and strain in the rock's layers vary with time when the lasting forces act on the boundary. They increase rapidly at initial stage and decrease steadily after reaching the peak value. Phenomena of stress relaxation are significant for studying the tectonic evolution.

The urban thermal distribution characteristics and its variation are dynamically monitored and synthetically analyzed by using GIS technology. The meteorological satellite data serve as main information source, assisted as auxiliary information sources by the landsat satellite TM data, land use thematic maps and meteorological observed data. A correlated pattern on the ground surface brightness temperatures and air temperatures has been studied and established with good performance of application.
