地质单位财务管理咨询刍议

地质单位对自身无力解决的重要财务管理问题应该寻求外部咨询机构的有效帮助，针对地质单位财务管理中存在的主要问题提出需要咨询课题，而咨询机构通过对地质单位的财务状况进行调查分析后，提出科学、合理有效的财务管理改善方案和指导实施方案。     

张家口地下热水资源成因探讨

张家口地热资源丰富，通过对区内地热成矿机制，成矿规律的分析认为，以祁吕系为主的多构造体系复合部位控制了本区地下热水的形成与分布，本区地下热水是大气降水经深循环而成，经计算深循环的深度达为2600m，张家口南部地区有很多个热水异常点，是具有远景意义的地热区。     

邯峰矿区古构造应力场与构造演化

采用共轭剪节理应力反演方法,恢复了邯郸-峰峰矿区晚古生代以来的3期古构造应力场,进而探讨了煤田构造的演化历史,将其分为4大阶段：①中生代早期近NS向挤压,煤系后期改造初动期;②中生代晚期SE-NW向挤压,奠定煤田构造格架的基础;③中生代末至古近纪NW-SE向拉张,煤田构造格架定型;④新近纪以来近东西向拉张,煤田构造的现代活动.     

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。     

États de contraintes et mécanismes d'ouverture et de fermeture des bassins permiens du Maroc hercynien. L'exemple des bassins des Jebilet et des RéhamnaStates of stresses and opening/closing mechanisms of the Permian basins in Hercynian Morocco. The example of the Jebilet and Réhamna Basins

The fracturing analysis in the Permian basins of Jebilet and Rehamna (Hercynian Morocco) and the underlying terranes allowed us to suggest a model for their opening. Three tectonic episodes are distinguished: a transtensional episode NNE–SSW-trending (Permian I), occurring during the opening along sinistral wrench faults N70–110-trending, associated with synsedimentary normal faults; a transpressive episode ESE–WNW-trending (Permian II), initiating the closure, the normal faults playing back reverse faults and the N70 trending faults dextral wrench faults; a compressional episode NNW–SSE (post-Permian, ante-Triassic), accentuating the closure and the deformation and putting an end to the Tardi-Hercynian compressive movements.

A comparison of tectonic ambient shear stress value in China with that in western USA

Introduction The stress status of the earths crust is closely related to global structure, the direction of plate movement, the drive mechanism of plate, earthquake cause, etc. Therefore the researches of the stress status of the earths crust and the process of dynamic evolution are paid a great attention to by many people around the world (Zoback, Zoback, 1980; Zoback, et al, 1989; Zoback, 1989; Spence, 1997; Fuchs, 1997; Plenefish, Bonjer, 1997; Muller, et al, 1997; XU, et al, 1989; WAN…     

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。     

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.
