TRANSVERSE STRUCTURES FEATURES OF DIFFERENT DEPTHS DERIVED FROM BOUGUER GRAVITY ANOMALIES IN THE SOUTHERN SEGMENT OF TAN-LU FAULT ZONE

To research the faults distribution and deep structures in the southern segment of Tan-Lu fault zone(TLFZ) and its adjacent area, this paper collects the Bouguer gravity data and makes separation by the multi-scale wavelet analysis method to analyze the crustal transverse structure of different depths. Meanwhile Moho interface is inversed by Parker variable density model. Research indicates that the southern segment of TLFZ behaves as a NNE-directed large-scale regional field gravity gradient zone, which separates the west North China-Dabie orogen block and the east Yangtze block, cutting the whole crust and lithosphere mantle. There are quite differences of density structures and tectonic features between both sides of this gradient belt. The sedimentary and upper crustal density structure is complex. The two east branches of TLFZ behave as linear gravity anomalous belt throughout the region, whereas the two west branches of TLFZ continue to extend after truncating the EW-trending gravity anomaly body. The lower crustal density structure is relatively simple. TLFZ behaves as a broad and gentle low abnormal belt, which reflects the Cretaceous-Paleogene extension environment caused graben structure. The two west branches of TLFZ, running through Hefei city, extend southward along the west margin of Feidong depression and pinch out in Shucheng area due to the high density trap occlusions in the south of Shucheng. The Feizhong Fault, Liu'an-Hefei Fault, and Feixi-Hanbaidu Fault intersect the two west branch faults of TLFZ without extending to the east. Recent epicenters are mainly located in conversion zones between the high-density and the low-density anomaly, especially in TLFZ and the junction of the faults, where earthquakes frequently occurred in the upper and middle crust. As strong earthquakes rarely occur in the southern segment of TLFZ, considering its deep feature of abrupt change of the Moho and intersections with many EW-trending faults, the hazard of strong earthquake cannot be ignored.     

南海东北部陆架边缘第四纪高分辨率层序地层和沉积体系演化及其控制因素

The northeastern shelf margin of the South China Sea(SCS) is characterized by the development of large scale foresets complexes since Quaternary. Based on integral analysis of the seismic, well logging and paleontological data, successions since ～3.0 Ma can be defined as one composite sequence, consist of a set of regional transgressive to regressive sequences. They can be further divided into six 3 rd order sequences(SQ0–SQ5) based on the Exxon sequence stratigraphic model. Since ～1.6 Ma, five sets of deltaic systems characterized by development of wedge-shaped foresets complexes or clinoforms had been identified. High-resolution seismic data and the thick foresets allowed further divided of sub-depositional sequences(4 th order) of regression to transgression, which is basically consistent with published stacked benthic foram O-isotope records. Depositional systems identified in the study area include deltaic deposits(inner-shelf deltas and shelf-edge deltas), incised valleys, and slope slumping massive deposits. Since ～1.6 Ma, clinoforms prograded from the southern Panyu Lower Uplift toward the northern Baiyun Depression, shelf slope break migrated seaward, whereas the shelf edge of SQ0 migrated landward. The development of incised valleys in the continental shelf increased upward,especially intensive on the SB3 and SB2. The slumping massive deposits increased abruptly since SB2, which corresponds to the development of incised valleys. The evolution of depositional systems of continental slope mainly controlled by the combined influence of sea level changes, tectonic movements, sediment supply and climate changes. Since ～3.0 Ma, relative sea level of the northern SCS had been experienced transgression(～3.0 Ma BP) to regression(～1.6 Ma BP). The regional regression and maximum transgressions of the composite sequences were apparently enhanced by uplift or subsidence related to tectono-thermal events. In addition,climatic variations including monsoon intensification and the mid-Pleistocene transition may have enhanced sediment supply by increasing erosion rate and have an indispensable influence on the development of the incised valleys and 5 sets of deltaic systems since ～1.6 Ma.     

主要造岩矿物微波敏感性试验研究

采用频率2 450 MHz多模谐振腔对11种常见主要造岩矿物试样进行了微波辐射试验。根据升温速率和温度增量对其微波敏感性进行了研究。对赤峰玄武岩、鞍山辉长岩和昆明砂岩进行了矿物成分测试,根据其矿物成分组成预测3种岩石的微波吸收能力,通过微波辐射试验对预测结果进行了验证。然后对3种岩石进行了单轴压缩强度测试,研究了微波辐射后岩石的强度折减与岩石微波吸收能力的关系。结果表明：主要造岩矿物的微波吸收能力可分为3类,且表现出非常不同的微波吸收能力;根据岩石的矿物成分组成可预测岩石的微波吸收能力,含有强微波吸收能力矿物的岩石也具有较强的微波吸收能力;岩石的微波吸收能力越强,微波辐射后岩石单轴压缩强度的折减程度越大。

公路积水阻断与降雨关系的探讨

利用2011—2013年全国公路积水阻断资料,分析了公路积水阻断的时空分布特征,并对公路积水阻断与不同时效降雨的关系进行了探讨。结果表明,公路积水阻断事件发生时间主要集中在5—9月,其中7月最为频繁,公路积水阻断事件以07:00—14:00为第一多发时段,16:00—20:00为次多发时段。公路积水阻断与前24h内的降水关系更为密切。区域不同,公路积水阻断随各强度降水变化的特点也不尽相同。经过开立方根处理后的降水因子与公路积水阻断发生的频次服从于高斯分布。其中,区域1公路积水阻断与处理后的1h最大降水因子关系密切,相关系数大于0.91;区域2和3公路积水阻断与处理后的6h最大降水因子关系密切,相关系数均在0.8以上;区域4公路积水阻断则与处理后的24h最大降水因子关系密切,相关系数在0.75左右。对于任何一个区域,诱发公路积水阻断的不同时效降水都处于一个较大的空间。对于给定的降水量只能判断公路积水阻断发生的可能性大小。     

接收函数方法估计Moho倾斜地区的地壳速度比

造山带地区的复合力系作用往往使Moho界面发生变形,局部表现为倾斜状态.为了得到这些区域精确地壳速度比结构,本文基于H-κ方法发展了H-κ-θ方法.该方法不仅考虑了倾斜Moho层的响应,同时利用径向和切向接收函数信息,增加了对扫描的约束.利用该方法对青藏高原东南缘地壳厚度和速度比结构进行研究,结果表明：研究区内地壳明显存在不均匀性,松潘—甘孜地体平均地壳厚度约为60 km,四川盆地西缘约为47 km,扬子地台约为43 km,三江块体和扬子地台东南缘已接近正常地壳厚度;松潘—甘孜地体与扬子地台相邻部位地壳平均地震波速度比（V_p/V_s）普遍偏高,且四川盆地西侧发现一绕盆地边缘的弧形高V_p/V_s异常区（>1.88）,我们推测该异常可能由青藏高原向东逃逸的地壳流体受到高强度的四川盆地阻挡,在其西侧堆积所致.
