阿尔金地区构造应力场及其对金属矿产分布的控制作用

构造应力场研究可以为区域矿产预测提供依据。主要根据节理、擦痕的测试分析，结合区域构造解析，确定阿尔金山东西向拉配泉－－红柳沟构造带经历了三期不同方向的应力作用：印支期以前的南北向挤压作用，印支－燕山期的北西－南东向的挤压和中生代晚期－新生代北东东－南南西向的挤压；并利用有限元数值模拟前两期构造应力场的演变过程，进而讨论了区域构造应力场对内生金属矿产分布规律的控制作用指出了区域寻找大型内生金属矿产的有利地段。     

Fracturation d'âge Aptien supérieur sur la bordure orientale de la plate-forme arabique (Haushi-Huqf,Oman)Aptian faulting (Shu'aiba Formation) on the eastern edge of the Arabian Platform (Haushi-Huqf,Oman)

In the Haushi-Huqf (Eastern Central Oman) as in other parts of the Arabian platform, a major sedimentary break is recorded between the Early Aptian carbonates (Shu'aiba Formation) and the Albian orbitolinid-rich marls (Nahr Umr Formation). The unconformity corresponds to a succession of events: (1) a brusque interruption of the regressive sequence of the Shu'aiba limestone (algae and small rudistid build-ups); (2) a stratigraphic gap related to the Late Aptian; (3) the development of a thick ferruginous crust (hardground) that covered the top surface of the Shu'aiba; the hardground is related to a forced flooding surface; (4) the Shu'aiba was rapidly drowned and buried under the Nahr Umr marls. Moreover, the Shu'aiba limestone was subject to faulting NW–SE-trending normal faults before lithification and formation of the ferruginous crust. The faulting episode is clearly dated: post-Early Aptian and pre-Albian. The signification of the faulting remains hypothetical. The syndiagenetic NW–SE normal faults may correspond to ‘en echelon’ faults, combined with transcurrent fault movements (for example the Haushi-Nafun Fault). The possible causes of these intra-platform transcurrent movements are discussed. To cite this article: C. Montenat, P. Barrier, C. R. Geoscience 334 (2002) 781–787.

我国黄铁矿矿床类型、分布规律及前景评估

中国黄铁矿资源丰富，按元素和矿物组合的不同，其矿床类型可分为：黄铁矿矿床；黄铁矿型铜矿床；含锌、铜黄铁矿型矿床；黄铁矿型多金属矿床；含钨黄铁矿型铜矿床；含锡黄铁矿型矿床；含金黄铁矿型矿床。最主要的成因类型是海底喷气沉积矿床，它广泛分布于不同时期的造山带及早前寒武纪克拉通。黄铁矿形成的构造环境可分为５种，即：边缘浅海或优地槽环境；上叠的断裂坳陷带；洋中脊；岛弧地带；陆相火山盆地。     

阿尔泰造山带构造演化研究中的几个关键问题剖析

对阿尔泰山地区的构造格局、构造变质、岩浆岩时代、动力热事件和构造区类型归属等几个地学基础问题进行深入细致研究的基础上，反演了阿尔泰地槽造山带形成和演化的递进历程。     

湖北省随枣地区推覆构造格局的研究

研究区构造格局的基本特征是上地壳多层次自北而南的逆冲—拆离，柳林、洪清、大洪山３条逆掩断层与深部拆离面一起组成了尖端指向南的楔形薄皮构造。逆冲系统以背驮式扩展演化。多层次推覆构造格局因后期高角度断裂的切割破坏而复杂化，构造格局定型时代为燕山期     

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.
