江南隆起东端伸展构造的识别及其意义

通过对屯溪流塘盆地典型伸展堆叠构造几何学和运动学的解剖，以及对其它几个伸展构造实例的分析，指出伸展构造在江南隆起的存在，它们的形成主要是重力作用的产物，遍及中、新生代。这种特征构造的解剖有助于深化认识江南隆起的构造特点和演化历史。     

Relocation of the October 9, 1505 Earthquake with M63/4

There have been 12 possible locations of the earthquakes occurring in the South Yellow Sea since 1505.In this paper,the location of the earthquake that occurred in 1505 has been determined by the collection of more historical data of the influenced field,referring the isoseismal data of earthquakes with the epicentral intensityⅨ and combining geophysical field data with tectonic condition,due to its great influence on seismic safety assessment of some significant engineering.     

Attenuation of coda waves and Q c value beneath the Chengdu telemetered seismic network

Based on the single scattering model of coda power spectrum analysis, digital waveform data of 50 events recorded by the real-time processing system of the Chengdu telemetry network are analyzed to estimate the Q _c values of earth medium beneath the Chengdu telemetry network for several specified frequencies. It is found that the Q _c shows the frequency dependency in the form of Q _c = Q ₀ f ⁿ in the range of 1.0 to 20.0Hz. Estimated Q ₀ ranges from 60.83 to 178.05, and n is found to be 0.713 to 1.159. The average value of Q ₀ and n are 117 and 0.978 respectively. This result indicates the strong frequency dependency of the attenuation of coda waves beneath the Chengdu telemetry network. Comparing with the results obtained in other regions of the world, it is found that Q ₀ ⁻¹ value and its change with frequency are similar to those in regions with strong tectonic activity.

Measurement and research method of metallogenic depths of Jiaojia orefield and Linglong orefield Shandong Province, China

Taking the contribution of the tectonic force to the total hydrostatic pressure into account, the author puts forward a new method on the calculation of the depth of petrogenesis and metallogenesis which is summarized as follows: first the tectonic added hydrostatic pressured P_s is subtracted from the total hydrostatic pressure P, then using their difference P_r, according to the general method the depth of petrogenesis and metallogenesis can be determined in consideration of lateral constraint. By the new method the following data on the depths of the metallogenesis are obtained: 2 243.6 m (No. I and No. II veins with metallogenic epoch of 105 Ma) and 1 632. 38 m (No. III vein with 105 Ma) for Jiaojia orefield, and 3 454.97 m (NE-trending zone with 213.2 Ma), 1 902.79 III (ENE-trending zone with 100.28 Ma), 1 090.97 m (NE-trending zone with 80.67 Ma) and 720.55 m (NNE-trending zone with 71.86 Ma) for Linglong orefield.

Paleogeographic maps of the Japanese Islands: Plate tectonic synthesis from 750 Ma to the present

Abstract A series of paleogeographic maps of the Japanese Islands, from their birth at ca 750–700 Ma to the present, is newly compiled from the viewpoint of plate tectonics. This series consists of 20 maps that cover all of the major events in the geotectonic evolution of Japan. These include the birth of Japan at the rifted continental margin of the Yangtze craton ( ca 750-700 Ma), the tectonic inversion of the continental margin from passive to active ( ca 500 Ma), the Paleozoic accretionary growth incorporating fragments from seamounts and oceanic plateaux ( ca 480-250 Ma), the collision between Sino-Korea and Yangtze (250–210 Ma), the Mesozoic to Cenozoic accretionary growth (210 Ma-present) including the formation of the Cretaceous paired metamorphic belts (90 Ma), and the Miocene back-arc opening of the Japan Sea that separated Japan as an island arc (25-15 Ma).

再论塔里木板块的归属问题

长期以来，对塔里木板块属于华北板块？扬子板块？还是一个独立的板块？一直存在争议。本文根据塔里木板前寒武纪基底的性质，古生代沉积建造序列，生物古地理区系的面貌和古地磁资料认为：（１）塔里木是属于前寒武纪陆壳基底的独立板块，与周边板块之间的存在不同规模的洋盆；（２）早古生代时，塔里木位于南半球，更接近于扬子板块，而远离华北板块（３）在古生代一中生代时，塔里木板块与周边坡板块先后碰撞，直到三叠纪末，塔里
