云南丽江地区断裂构造岩岩组动力学研究

丽江地区构造岩岩组动力学研究表明，研究区内中更新世末构造主压应力保持在北西至北西西方向变化；晚更新世中期之后构造主压应力方向则以北北东至北东方向为主变化，并有逐渐向近南北向转化的特点。因此玉龙雪山东麓断裂在中更新世末曾有过左旋压扭活动为主的历史，兼有左旋、右旋的活动过程，1996年2月3日丽江M7．0地震的破裂过程继承了晚更新世后期断裂的活动特点。

The experimental studies on electrical con-ductivities and P-wave velocities of anortho-site at high pressure and high temperature

Introduction The measurements of the compressional wave velocity and electrical conductivity of minerals and rocks are of fundamental importance to look into the earths interior, including composition, geotherm, generation and distribution of fluids and melts. Hydrous minerals formed by metamatu-siom are abundant within the earth. Previous studies have been carried out on the dehydration effect on the electrical conductivity and wave velocity of rocks such as serpentine, amphibole, most of whi…     

Models of passive margin inversion: implications for the Rhenohercynian fold-and-thrust belt, Belgium and Germany

Positive tectonic inversion is related to the transmission of compressional stresses along a décollement into the foreland of an orogenic zone. This stress and strain concentration in regions remote from the main orogenic front is commonly related to the presence of pre-existing rheological heterogeneities such as normal syn-depositional faults. During inversion, these pre-existing normal faults are reactivated as reverse faults. Tectonic inversion in the Rhenohercynian fold-and-thrust belt during the Variscan Orogeny shows that inversion is likely synchronous with the onset of collision in the hinterland. Here, we present the results of a simplified thermo-mechanical model (STM) which allows one to study strain partitioning between two orogenic zones. We show that, if the two orogenic zones have the same mechanical properties, the viscosity of the décollement, which links them, controls the initial strain partitioning. During subsequent finite shortening, erosional processes determine the partitioning of strain rate. The presence of a weak structure in the inverted zone and of a low-viscosity décollement leads to initial strain concentration in the inverted track rather than in the collision zone and a progressive decrease in strain partitioning between the two orogenic zones. The STM results are in good agreement with results of a 2D finite-element model. We conclude that, in the western part of the Rhenohercynian Massif, simultaneous uplift and deformation within the Mid-German Crystalline Rise (the main collision zone) and the Ardenne Anticlinorium (the inverted zone) lead to interpreting this orogenic event as a case of vice tectonic rather than the propagation of a ‘wave of folding’ towards the Variscan front, as suggested by previous authors.     

环渤海地区油气资源探查的思考

回顾过去渤海勘探实践的经验，对于指导今后的研究工作是十分重要的。40年来渤海地区发现大量新老第三纪陆相石油资源，成为中国的重要产油区，也积累了丰富的勘探经验。深化环渤海地区油气资源的探查，首先应考虑前新生代海相油气资源。但其勘探是高难度的，前景是诱人的。应该认真贯彻下列认识原则：（1）区域指导局部；（2）深部制约浅层；（3）在地震处理解释创新的同时，大力发展综合地质地球物理研究。
