A synthetic earthquake prediction parameter, seismological anomaly, using the CAPSeis software to analyze the nine parameters of b-value, N-value, η-value, C-value, D-value, scismless value, GL-value, and Rm-value in southeastern coastland of China, were obtained in this paper. The probability prediction effect of seismological anomaly is much better than the statistical probability of the parameters mentioned above.     

Experimental Study of Wave Pressure on a Breakwater Pier

Test studies on the wave pressure on a breakwater pier show that the influence of transmissivewave pressure on the outside wall of the breakwater pier is considerable,when the width of the pier is notvery large.The variations of transmissive wave pressure on the breakwater pier with different widths arecompared and the relationship is obtained between relative transmitting distance b/L and wave pressurereduction factor K,which may be used in the design of similar breakwater piers.

两次大震的视电阻率各向异性特征

对1976年松潘7．1级和唐山7．8级地震的地电阻率变化及各向异性特征作了较全面的分析,并从理论上作了一定程度的解释。结果表明,震前地电阻率变化的各向异性是客观存在的,各向异性主要有两种表现,一是不同台站的方位性差异：二是同台不同测向的差异。这种各向异性主要外观因素是台站的震中距、方位、测向、介质的力学因素和地震本身的机制;内在因素主要是原生裂隙的膨胀、闭合和排列、新生裂隙或破裂的发育、贯通、排列受应力场的作用。     

内蒙古赤峰柴胡栏子金矿基性麻粒岩包体特征及其成矿动力学意义

柴胡栏子金矿位于华北板块北缘,属中温热液蚀变岩型金矿。金成矿与矿区北部的早中生代辉石闪长岩体有密切关系。在辉石闪长岩体内发育大量包体,可以分为基性麻粒岩和角闪岩两类包体。包体的地球化学、形成温压条件表明基性岩包体为来源于大陆下地壳的基性麻粒岩包体,来源深度大约相当于下地壳中部-中上部位置,为早中生代时期底侵作用的产物。角闪岩包体来源于下地壳上部-中地壳下部位置,被上升岩浆带至地壳浅部。包体和寄主岩石具有相似的地球化学和氧、铅、锶、钕同位素特征,说明二者具有相同的岩浆来源。基性麻粒岩包体为底侵作用早期形成的堆晶岩受到后续岩浆的烘烤发生麻粒岩化形成。基性麻粒岩和寄主岩石辉石闪长岩与金矿床形成的密切时空关系显示底侵作用对柴胡栏子金矿含矿流体形成、运移和矿质富集有重要控制作用,其中 H2O和CO2等挥发性组分对控制流体形成和演化有至关重要作用。基性麻粒岩包体发育为成柴胡栏子金矿成矿物质来源于深部提供了有力的证据。

Shaking table tests and numerical simulation of dynamic properties of underground structures

It is considered thai the damage of the underground structures caused by earthquakes is minor for a long time. However, the catastrophic damages induced by several recent earthquakes （e. g. Kobe earthquake in 1995 ） revealed that the study on the dynamic properties of the underground structures is indispensable. The dynamic behavior and damage mechanism of underground structure are analyzed by using shaking table tests （ both shallow-and deep-buried） and numerical simulation （3D FEM） including horizontal and vertical input motions, individually and simultaneously. From the results, the underground structure collapsed due to strong horizontal forces although vertical deformation is not negligible. The vertical excitation increases the response of structure, especially the stress and shear stress at the upper section; the soil influenced the property of soilstructure system. In the same excitation, the response in shallow-buried test is larger than deep case. Both overburden and vertical earthquake play important roles in the response of structure and those are two critical aspects in the design of the large-span underground structures, such as subway stations.

Metallogenic origin of Sipingshan hot spring gold deposit in Hulin of Heilongjiang and its metallogenic mode

Sipingshan gold deposit is gold-bearing sillcalite in type. There only exist a few kinds of sulfide in the ore and it is lower in content. The gold degree is lower. Au is closely related to the Ag,Cu,Pb,As and Hg elements. The upper sillcalite has Eu and Ce negative anomaly,and the lower sillcalite has Eu positive anomaly. however,the hot spring cemented breccia and rhyolite porphyry have Eu negative anomaly;the S isotope component has deep-seated magmatic sulfur and terrestrial sulfate characteristic;and t...
