The wenchuan earthquake in 2.08 and geo-hazards triggered by the earthquake caused large injuries and deaths as well as destructive damage for infrastructures like construction, traffic and electricity. It is urgent to select relatively secure areas for townships and cities constructed in high mountainous regions with high magnitude earthquakes. This paper presents the basic thoughts, evaluation indices and evaluation methods of {1. security evaluation, water and land resources security demonstration and integrated assessments of geo-environmental suitability for reconstruction in alp and ravine with high magnitude earthquakes, which are applied in the worst-hit areas （1. counties）. The integrated assessment shows that：（1. located in the Longmenshan fault zone, the evaluated area is of poor regional crust stability, in which the unstable and second unstable areas account for 79% of the total; （2. the geo-hazards susceptibility is high in the evaluation area. The spots of geo-hazards triggered by earthquake are mainly distributed along the active fault zone with higher distribution in the moderate and high mountains area, in which the areas of high and moderate susceptibility zoning accounts for 40.1. of the total; （3） {1. security is poor in the evaluated area, in which the area of the unsuitable construction occupies 73.1., whereas in the suitable construction area, the areas of {1. security, second security and insecurity zoning account for 8.3 %, 9.3% and 9.3 % of the evaluated area respectively; （4） geo-environmentai suitability is poor in the evaluated area, in which the areas of suitability and basic suitability zoning account for 3.5% and 7.3% of the whole evaluation area.

Mineralization and Ore-controlling Implications of Low-angle Faults

Acta Geologica Sinica(English Edition) 1999年第4期73卷 438-446页

Abstract Low-angle faults include those occurring in thrust-nappe structures in a compressive setting and the detachment of metamorphic core complexes in an extensional setting. All low-angle faults have their own particularities. The low-angle fault plays an important role in controlling over some endogenetic metallic ore deposits. Based on studies of the Xiaoban gold deposit, Xinzhou gold deposit, and Longfengchang polymetallic ore deposit, and comparisons with other mines, the authors conclude the ore-controlling implications of low-angle faults as follows. (1. Because of high temperature and high pressure, as well as strong ductile deformation, the internal energy of the elements rises in the large-scale deep ductile low-angle faults, which causes the elements to activate and differentiate from the source rocks, forming ore-bearing hydrothermal solution, and bring mineralization to happen. (2. When rising from depths and flowing along the low-angle faults, the ore-bearing hydrothermal solution will alter and replace the tectonites in the fault zone. The rocks of the hanging side and the heading side differ in lithology, texture and structure, which results in changes or dissimilarities of the physical-chemical conditions. This destroys the balance of the hydrothermal solution system and causes the dissolved ore-forming elements to precipitate; as a result, a deposit is formed. Therefore, the meso-shallow ductile-brittle low-angle faults play the role of a geochemical interface in the process of mineralization. (3) Low-angle faults are often one of the important host structures.

为探讨川东北元坝地区长兴组岩石中钠长石矿物的成因,对其进行了利用电子显微镜、能谱仪及稀土元素测定等分析测试。结果表明,显微镜下钠长石主要呈分散状分布,明显的聚片双晶现象,交代早期成岩矿物;钠长石与石英、黄铁矿伴生;稀土元素总量较低,分布曲线较缓,轻稀土相对富集、重稀土元素相对亏损,正Eu异常。研究认为,钠长石的成因与深部热液活动有关。根据川东北地区晚二叠世拉张构造背景,推测其是在二叠世晚期峨眉地裂运动玄武岩喷发的构造背景下生成的,钠长石的发现为研究该区长兴期构造、岩浆活动、"热事件"等研究具有重要的地质意义。

[研究目的]胶东是全球著名的金成矿区,金矿床主要受断裂构造控制,该区尚有很多断裂是无矿的,以往对断裂的深部形态及赋矿断裂与无矿断裂的区别特征缺乏深入研究。[研究方法]本文通过在胶东西北部实施重、磁、电长剖面和穿越主要金矿集区的广域电磁剖面、反射地震剖面,揭示了断裂深部特征,为赋矿断裂和无矿断裂的识别提供了重要证据。[研究结果]地球物理探测表明,胶西北地区的断裂构造有陡倾角的深断裂、缓倾角的铲式断裂和陡倾角的小断裂,其中控矿的三山岛、焦家和招平断裂均是铲式断裂。结合对金矿床的研究发现,矿床主要赋存于缓倾角断裂中,矿体呈阶梯分布特征,陡倾角的深断裂中未见明显的金矿化蚀变,现今金矿床赋存的最大深度在5 km左右。[结论]综合分析认为,低角度拆离断层和连续性不好的高角度小断层有较好的物理圈闭条件,有利于矿化富集;而产状平直、陡倾的深断裂不具备物理圈闭的条件,不利于成矿。胶东型金矿的找矿方向应集中于缓倾角的铲式断裂及其派生、伴生的陡倾角小断裂附近。
