Based on the geological background , ore?deposit and structural geology, the paper analyzed the geological character istics and metallogenic mechanism of the gold deposit and suggests that the deposit occurring in the limestone and metamorphic siliceous rocks in the third litholog ic unit of Devonian Tuokesalei formation is controlled by the Duolanasayi shear zone characteristic of secondary shear deformation, mineralizaion and multiphased vei n mineralization?.

笔者从地质背景、矿床地质，以及控矿构造分析了多拉纳萨依金矿矿床特征及其成矿机理；明确了矿床产于泥盆系托克萨雷组第三岩性段的灰岩－浅变质－硅质岩系，受控于多拉纳萨依韧性剪切带；控矿构造具有二次韧性剪切变形、矿化和多期次脉体矿化的特征，显示出构造活动的多期次性与复杂性，阐明了构造期次与矿化之间的关系。？

传统方法研究板块构造运动主要是以地质时间尺度的地质资料，用地球物理方法研究各种运动和它们相互关系，探索它们的演化过程和动力学机制，推测其运动特征，然而大部分还停留在假设和推测的水平上。

The writer conceptualizes the hydrogeol ogical model, and the corresponding three dimension mathematical model has been built,the Finite Difference Method is used to solve the mathematical model. After calibration and verification of the model, the adopted geology parameters basically accord with the concrete hydrology geology condition.

The application of sulfur isotope tracing involves the physical and chemical conditions, origin of ore-forming minerals, denudating degree of orebody, ore enriching position and genesis types of deposits. In the application, the geology of the hydrothermal deposit should be well understand to distinguish metallogenic epochs and judge the isotopic fractional equilibrium state, combined with the Ohmoto mode to study the factors possibly affecting hydrothermal fluid system.

在总结前人研究基础上，综述了硫同位素在热液成矿作用中成矿物理化学条件、成矿物质来源、矿体剥蚀程度、矿化富集部位、矿床成因类型等的示踪意义，认为硫同位素示踪应用须在了解热液矿床基础地质前提下，准确区分成矿期次，判别硫同位素分馏平衡状态，结合Ohmoto模式综合研究影响成矿热液体系的各种因素才可以赋予同位素准确的地质内涵。

其次，在系统分析潍坊市地质与水文地质条件、气象、水文、地下水动态和有关地下水均衡试验、排灌试验、地下水开发利用等各项基础资料的同时，采用多种方法综合分析确定各项计算参数，并分项计算确定各水资源分区的补给量、排泄量、不同类型区地下水间的重复计算量。

Besides various interferences, the wave front diffusion, the ground absorption and the attenuation are all the causes of a weak seismic reflection and, plus the complicated superficial geologic setting and the reservoir bed features of low amplitude, low porosity and low permeability of the compacted thin detrital rock in HJQ, the conventional seismic amplitude fidelities do not meet the criteria of the seismic inversion.

除各种干扰外，地震波传播过程中的波前扩散、大地吸收、衰减等使地震反射能量变弱，加之杭锦旗地区复杂的表层地质条件和低幅、低孔、低渗致密性薄层碎屑岩的储层特点，使常规保幅地震资料离地震反演的要求还有差距，并且反演技术本身不具备噪音识别功能，包含噪音的反演必然会影响地质效果。
