  特征的矿床
     In general, the mineral deposition is a complex nonlinear dynamic process. Minerals in hydrothermal system will finally deposit at appropriate place through a complex nonlinear feedback effect among the structural stress, fluid flow and fluid-rock reaction and lead to the fractal and chaotic characteristics of deposits and grade distribution.
     总之 ,成矿物质的沉淀过程是一个复杂的非线性动力学过程 ,矿物在热液体系中通过构造应力、流体流动、流体岩石反应等之间的复杂非线性反馈作用 ,最终在合适部位沉淀下来 ,形成了各种具分形与混沌特征的矿床和品位分布

In this paper the characteristics of the texture of clastic sediments and their chemical and mineral compositions formed in running water in several caves are discussed, on the basis of which the karst cave development and the influence of paleo-environment upon it are studied. The quartz sand surface textures are studied with scanning electron microscope and the results show that the sediments of early caves in Goupitan, Guizhou Province were formed under the strong hydrodynamic condition. The geochemical characteristics...

In this paper the characteristics of the texture of clastic sediments and their chemical and mineral compositions formed in running water in several caves are discussed, on the basis of which the karst cave development and the influence of paleo-environment upon it are studied. The quartz sand surface textures are studied with scanning electron microscope and the results show that the sediments of early caves in Goupitan, Guizhou Province were formed under the strong hydrodynamic condition. The geochemical characteristics of harfour deposits in the caves are compared and the paleoclimate environment is obtained. The geochemical characteristics of deposits in Luota, Hunan Province indicate that during the early-middle pleistoncene the climate was warm and moist and at the end of pleistoncene it was arid. The mineral composition of the sand deposit can be used to study the system of the caves. A karst cave system of E-W direction is found in pengshui, Sichuan Province.

本文通过对岩溶洞穴碎屑沉积物结构特征及其矿物、化学成分的研究,探讨岩溶洞穴的发育和形成的古环境.对洞穴石英砂表面微结构作扫描电镜观察研究,表明贵州构皮滩早期洞穴碎屑是在水动力较强的条件下形成的;对洞穴湖相沉积物作了地球化学特征的对比,从而获得不同的古气候环境.如洛塔洞穴堆积物的地球化学特征反映早中更新世时为温暖湿润的气候,而晚更新世时为较干旱气候;通过洞穴砂的矿物成分分析,探索了洞穴本身的展布,为四川彭水岩溶区东西向洞穴系统的存在提供了证据.

A comparison is made between Changyan Cu-Ag deposit in this area and Zhileng Tou Au-Ag deposit in Zhejiang province, and some similarities in regional geological settng, the characteristic of deposit, the origin and the resource of material are shown. Therefore, this paper proposes that...

This paper is based on the analysis of the condition of the regional metallogeny (Presinian Jinshan group, regional deep fault and the late Yanshanian period infermediate-acidic small intrusion) in Shanghai. A comparison is made between Changyan Cu-Ag deposit in this area and Zhileng Tou Au-Ag deposit in Zhejiang province, and some similarities in regional geological settng, the characteristic of deposit, the origin and the resource of material are shown. Therefore, this paper proposes that the prospecting of gold deposit in this area should be at the site of "three-in-one" of Jinshan group, deep faults and small intrusions.

本文在分析上海地区区域控矿条件(前震旦系金山群、区域深断裂及燕山晚期中酸性小侵入体)的基础上,以区内张堰铜银矿与浙江治岭头金银矿对比,显示两者在区域地质背景、矿床特征和成因及其矿质来源等方面均存在某些相似性。从而提出在区内金山群、深断裂和小侵入体“三位一体”地段寻找金矿的设想。

The quartz vein type gold deposits of xiaoqinling area are mainly distributed south to the Mesozoic granite batholiths such as Wenyu and Huashan and entirely hosted in Archean greenstone belt of Dangzchc group and early Proterozoic Khondalite series of Shuidigou group. Geological characteristics of deposits, nature of fluid inclusions within minerals and isotopes of hydrogen and oxygen show that ore-forming process consists of three important epoches. Ⅰ, Ⅱ and Ⅲ cpoches are respectively mineralized at...

The quartz vein type gold deposits of xiaoqinling area are mainly distributed south to the Mesozoic granite batholiths such as Wenyu and Huashan and entirely hosted in Archean greenstone belt of Dangzchc group and early Proterozoic Khondalite series of Shuidigou group. Geological characteristics of deposits, nature of fluid inclusions within minerals and isotopes of hydrogen and oxygen show that ore-forming process consists of three important epoches. Ⅰ, Ⅱ and Ⅲ cpoches are respectively mineralized at about 251-338℃ by metamorphic hydrothermal solution, at about 209-336℃ by mixed solution of metamorphic and meteoric hydrothermal solutions and at 155-178℃ by mete- oric hydrothermal solution. Concentration of ore-forming elements and theoretical re- search prove that mineralization is mainly contributed by epoch and negligibly by Ⅲ epoch. Complex source and intensive uniformizing during mineralization are demonstrated by isotopes of sulphur, carbon and lead. By comprehensive discussing, it is concluded that mineralization was caused by intracontinenal subduction during the Mesozoic prpgenesos collision orogeny between the Xouth and the North China plates. Further studyprospecting should be carried out according to the petrogenesis andmineralization model for collision orogeny proposed by Chen et al (1991).

小秦岭石英脉型金矿主要产在华山、文峪等中生代花岗岩基南侧的太古宙荡泽河群绿岩带和早元古代滴沟群孔达岩系中。矿床地质特征和矿物包裹体及氢氦同位素研究证明矿床形成经历了Ⅰ期251~338℃变质热液矿化、Ⅱ期209~336℃变质热液—大气降水热液混合矿化和Ⅲ期155~178℃大气降水热液矿化。成矿元素富集特点及理论研究证明矿化主要发生在Ⅱ期,Ⅲ期贡献甚微。S、C、Pb同位素指示战矿物质来源复杂,并在成矿时高度均一化。综合讨论揭示出矿床形成于中生代华南与华北古大陆板块碰撞造山过程的陆内俯冲作用,可按碰撞造山成岩成矿模式指导进一步的找矿和研究。
