Mineralization often is related to altered rocks. Landsat TM with two bands within the short infrared wavelength (1. 1-2.5 μm) supples the ability for altered rocks mapping. But the vegetation covery masks the altered rocks information and confuses the reflectance spectrum. Three methods were developed for altered rock mapping in middle density vegetation area. They are principal component analysis, least square fit and unmixing. These methods are successfully applied in DianQingGui area for disseminated...

The clay minerals distribution information which is related to disseminated gold deposits were extracted and mapped,

各种类型的热液型矿产经常与围岩蚀变相伴生,蚀变岩类是找矿标志之一。陆地卫星TM 数据在短波近红外范围内有二个波段,这两个波段的信息可用来进行蚀变岩的制图。可是在有 部分或中等密度的植被复盖区,由于植被和蚀变岩类的反射光谱特性比较相似,影响了TM数 据的制图能力。笔者开发了三种用来在中等程度植被复盖区进行蚀变岩类信息提取方法。这三 种方法是:直接主成分分析法、最小平方拟合法和混合单元分解法。在滇黔桂微细浸染型金矿 勘查中,这三种方法被成功地用来提取与金矿化有关的粘土蚀变岩类信息和制图。

It is common for almost all of large_and medium_size hydrothermal deposits to develop widespread hydrothermal alteration,accompanied by inspissation of ore_forming fluids.Fluid_rock interaction makes initial low_concentration fluid form the metamorphic zone with water_rich minerals,and cause free_water in solution to solidify in the alteration zone.the interaction between free_water and such components as C and S together with boiling and release of pressure will stimulate the depletion of free_water and the increase of metallic concentration in residual solution.The inspissation of fluids can appear in structural zones or pore fluids.Tectonic_altered rock mapping,experimental simulation,indicator element studies and mathematical modeling for the metasomatic profile can help to determine the inspissation ranges of ore_forming fluids and the dimensions of mineralization.Hence,the theory of fluid inspissation in water_rock interaction will provide a criterion for deciding the ore_forming metamorphic formation and predicting the reserves of ore deposits.

几乎所有的大中型热液矿床中都广泛存在着热液蚀变现象,且伴随强烈的成矿流体的浓缩作用。初始浓度较稀薄的含矿流体,通过水岩反应生成富水矿物的交代带使热液中的自由水固化在蚀变岩石中,热液中的自由水与C、S等组分反应而被大量地消耗,流体的减压沸腾都可极大地促进成矿热液中自由水的减少,从而使残余流体中金属浓度增高。可以通过构造-蚀变岩填图、实验模拟、特征指示性元素性状研究和交代剖面的数学模拟获得成矿溶液浓缩的幅度,进而判定矿化规模,通常在大、中型矿床中都发生过多次流体浓缩作用,依据水岩反应中流体浓缩理论,建立了含矿交代建造的识别准则,提出了应用流体包裹体成分的分析数据,进行矿床储量预测的理论和方法。

Fluid rock interaction makes initial low concentration fluid to form the water rich mineral containing metasomatic zone and cause free water in hydrothermal solution to solidify in the rocks of alteration zone. Interaction between free water and such components as C and S, boiling and release of pressure of solution stimulate the depletion of free water and the increase of metallic concentrations in residual solution.

Fluid rock interaction makes initial low concentration fluid to form the water rich mineral containing metasomatic zone and cause free water in hydrothermal solution to solidify in the rocks of alteration zone. Interaction between free water and such components as C and S, boiling and release of pressure of solution stimulate the depletion of free water and the increase of metallic concentrations in residual solution. Tectonic altered rock mapping experimental simulation, mathematical modeling for the metasomatic profile can help to determine the inspissation ranges of ore forming fluids and the dimensions of mineralization. Hence, the theory of fluid inspissation in water rock interaction provides a criterion for deciding the ore forming metasomatic formation and predicts the reserves of ore deposits.

工程地基的选址依据,本世纪中叶以前是地基范围内没有断裂,即避免断裂原则。60年代以后,工程选址的条件由避免断裂转变为考察断裂是否活动。美国率先制定了工程地基范围内活动断裂指标规范,认为具有非活动性断裂的岩体上可以构筑大型工程。花岗岩体规模大,整体性好...
