物探电法在锦州东港电力有限公司矿泉水水源地勘查的综合应用

锦州东港电力有限公司矿泉水水源地位于辽西中部断陷盆地锦州盆地的北端。地处中新生代上侏罗统及白垩系构成的对称向斜,NNE新华夏系断裂构造经由锦州盆地通过。工作区第四系覆盖6-14m,下伏孙家湾组(K2S)砂质泥岩、砂砾岩和义县组(K1y)火山碎屑岩、英安岩、安山岩及火山凝灰角砾岩。对该区进行地质水文资料综合分析的基础上,采用电阻率联合剖面、高密度电阻率法、电测深(电阻率、衰减时及极化率)多种物探电法综合勘查,确定断裂构造位置、产状及赋水性。经验证获得涌水量312t/d具有商业价值的矿泉水水源地。这一工作方法在辽西火山岩贫水区进行水资源勘查具有推广意义。     

信息科学与矿产预测

矿产预测实质上就是对成矿系统演化过程精确性表达的探索,现代信息科学的发展为理解成矿系统的非线性特性以及信息运动过程提供了必要的理论基础。通过信息与成矿信息、虚拟现实技术与成矿预测可视化和信息模型与成矿系统三个方面探讨信息科学的发展与矿产预测之间的紧密联系,预测未来成矿预测将向定量化、精细化的方向发展,对矿的定位预测从以分析为主向分析与综合相结合方向发展。     

世界内生磷矿地质及成矿规律

内生磷灰石型矿床在世界磷矿工业中的地位不断上升。世界内生磷矿可划分为超基性-碱性-碳酸岩类(占内生磷矿储量的90％以上,又分超基性-碱性-碳酸岩型、碱性-碳酸岩型、超基性-碱性岩型、超基性-碳酸岩型、碳酸岩型、碱性岩型六亚类),基性岩与超基性岩类,其它类等三大类。各类矿床主要岩石类型,矿物组合,岩体形态、产状、结构,矿体与矿石及其主要产地、大地构造位置等都各具特色。以成矿理论与成矿规律为指导,通过地、物、化、遥综合手段找矿将取得事半功倍的效果。

Numerical Simulation of Abnormal Wave Height Change Induced by Excavated Waterway with Boussinesq Equation

A nonlinear numerical model has been set up by use of Boussinesq Equation with finite differ-ence method,and has been applied to the simulation of the abnormal change of wave height induced by ex-cavated waterway.Numerical results demonstrate that the abnormal change of wave height is due to theadding of the reflected wave height induced by excavated waterway to the incident wave height.Becausethe angle between the incident wave and the axis of the waterway is smaller than the critical angle,the re-flected wave produced by the waterway may propagate to the breakwater and may be added with the inci-dent wave,then the abnormal change of wave height before the breakwater may be caused.So the wave re-flection caused by the change of water depth cannot be neglected.

Dynamic Analysis of Deformational Structures of the Xianniishan Fault Zone in the Three Gorges of the Yangtze River

Field investigation and laboratory work reveal that inhomogeneity of the deformation of the Xiannushan fault is mainly characterized by lateral zonation, longitudinal segmentation and downward stratification. Based on these results, a 3-D deformational structure model of the fault was established and its geometrical and kinematic characteristics in two main deformational stages i.e. the main Yanshanian and Himalayan were discussed. The directions of principal and the differential stresses in these two stages were determined by using conjugate joints, striations of fault planes and microstructures of the fault zone. The direction of σI is N-S in direction with differential stresses of 150-250 MPa in the Yanshanian, and N70E with a differential stress ranging from 80-120 MPa in the Himalayan.
