摘要文章论述了华东火山岩型铀矿找矿值得重视的地质问题：①铀成矿既可形成于浅源浅成低温条件，也可形成于深源深成高温或深源浅成中低温条件，在强调深源时，不是简单地认为是幔源就可以了，还必须强调壳幔作用的地质过程；②打破人为的&类型&划分，加强&铀成矿系统&的研究，更好地指导找矿；③研究基性脉体与铀成矿问题应注意构造、岩石矿物成分、成因、蚀变与成矿3大问题，注意寻找泥岩化作用强烈的破碎辉绿岩脉中的富铀矿；④火山盆地基底对铀成矿的作用主要是提供铀源，将基底对铀成矿的影响从感性认识推向理性认识，有效地指导找矿；⑤红盆与铀成矿关系可以从构造、古气候及时间分析研究中得出结论，它不仅仅是一个理论问题，而且有助于铀成矿预测；⑥隐爆角砾岩筒是铀成矿、成富矿的重要储矿构造，是华东火山岩型铀矿找矿的新领域。

According to model, lead zinc ore bodies of mineral deposit, celestite ore bodies and gypsum ore bodies are distributed by the incomplete dome shape. The sandstone type ore bodies like a curved surface shape, is on the top, wide distribution, which like the top cover of a mushroom. The limestone breccia type ore bodies, under the sandstone type ore bodies, with mostly irregular vein shape, lens body shape, locate at the root of the mushroom. Gypsum and celestite ore bodies, accompanying with limestone breccia type ore bodies with the shape of vein, lens body, distribute under the sandstone type ore bodies.

根据模型显示，金顶矿床铅锌矿体、天青石矿体和石膏矿体呈不完整的穹隆状分布，砂岩型矿体在上，为曲面状，分布广，似一蘑菇的顶盖，而灰岩角砾岩型矿体分布局限，部分产于砂岩型矿体之下，多为不规则的脉状、透镜体状，构成蘑菇的根部；石膏和天青石矿体主要与灰岩角砾型矿体相伴产出，呈脉状、透镜体状，多分布于砂岩型矿体下部。

Seven molybdenite samples from greisen ore body and quartz vein tungsten ore body associated with black tungsten ore were chosen for Re-Os isotopic dating and model age of (141.4±2.2) Ma~(158.2±2.2) Ma were obtained. The isochrone age of molybdenites from greisen type tungsten-tin ore body is (156.8±3.9) Ma, which indicates that its mineralogenetic epoch is at the Middle Jurassic, corresponds to the second stage of early Yanshanian period. And the model age for the samples from greisen ore body and from quartz vein ore body are (150.7±2.4) Ma~(158.2±2.2) Ma and (141.4±2.2) Ma~(151.0±2.4) Ma respectively, which indicates that the mineralization time of the quartz vein ore body is slightly earlier than that of greisen ore body.

文章选取云英岩型矿体及上部石英脉型钨矿体中与黑钨矿共生的辉钼矿7件，进行Re-Os等时线年龄测定，得到其模式年龄为(141.4±2.2) Ma~(158.2±2.2)Ma，其中云英型钨锡矿体中辉钼矿等时线年龄为(156.8±3.9)Ma，成矿时代为中侏罗世，对应于燕山早期第二阶段；从云英岩矿体中样品模式年龄为(150.7±2.4)Ma~(158.2±2.2)Ma，石英脉型矿体中样品模式年龄为(141.4±2.2)Ma~(151.0±2.4)Ma。

In the space, along with increased distance from the main ore-controlling structures, the frequency of P type of pyrite and their thermoelectricity also decreased gradually. Within one lode, from the upper to the lower parts of an ore body, the vertical change of pyrite in thermoelectricity as the follows:① when the ore body is stable, that is when the ore body is uniformly and continuously mineralized, the Dp andαvalues keep increased from shallow to deeper parts;② when an ore body is discontinuously mineralized, the Dp andαvalues have a wavy increasing tendency from the shallow to the deeper;③ when the deeper part of an ore body contains abundant, Co and Ni high mafic dykes, the Dp andαvalues of pyrite decreased from the shallow to the deeper parts of an ore body, that is, an reversed zoning of pyrite thermoelectricity occurs for pyrite in this situation contain more Ni and Co and belongs to N type.④ For the deposits hosted in the Archean metamorphic rocks, because all of the pyrite in this case is N-type, the vertical change of pyrite is not featured by the transition of pyrite type, but by the increased values of Vnp and α from the shallow to deeper parts of an ore body.

在空间域上，水平分带规律为：随远离主干断裂，矿脉中P型的出现频率逐渐降低或热电系数值逐渐变小；在同一条矿脉中，这是由于矿化不均匀性及脉岩的影响，由矿体的上部到下部，它的垂向变化特征可以有如下几种变化形式：①由矿体的浅部到深部，黄铁矿的Dp值、或α值呈稳定升高的趋势时，矿体往往表现为矿化均匀，连续性好、延伸稳定；②由浅部到深部，黄铁矿的Dp值、α值呈波状变化，但总体又具有增大的趋势时，所在的矿体连续性差；③当矿脉的下部发育有大量的基性脉岩时，由于基性脉岩中常含有较高的Co、Ni，使其中黄铁矿的Co、Ni含量较高而呈N型导电，由矿体的上部到下部，黄铁矿的Dp值、α值呈减少的趋势，而造成黄铁矿热电性特征的逆向分带，④产于太古代变质岩中的中深脉状金矿，由于其中的黄铁矿均为N型导电，所以垂向变化规律并不表现为导型的改变，只是Vnp值或α值从矿体的上部到下部由小变大。

Because the direct roof of the No.92 ore-body is the backfilling of the No.91orebody which is the cementing materials or non-cementing materials, and there are no-filled mined-areas in someplace. So there are large-scale hidden troubles on the top of the No.92 slowly inclined large and thick ore-body, then we must find a new mining technology which aims at the complex mining condition of the No.92 ore-body. The cutting nature of the No.92 ore-body is very poor, so choosing the rational drilling and blasting parameters and enhancing the overall technological economic benefits are also the urgent problems waiting to be solved in the exploitation of the No.92 ore-body. The No.92 ore-body, thin lodes and the exploitation process of the No.91orebody influence each other, the geo-pressure phenomena aggravates obviously in case of the mined-areas increase constantly, and the geo-pressure problem will be more and more serious when the No.92 ore-body be exploited on a large scale in the next step.

由于它的直接顶板就是开采91号矿体时的胶结或者非胶结的空区充填体，部分地段甚至是未充填的采空区，使92号缓倾斜厚大矿体的上部形成大范围的隐患区，因此，必须针对92号矿体复杂的开采技术条件，寻找新的采矿技术与工艺。92号矿体的可凿性极差，选择合理的凿岩爆破参数，提高凿岩爆破工作的总体技术经济效益，也是92号矿体开采急待解决的问题。92号矿体与细脉带、91号矿体开采相互影响，目前在采空区不断增大的情况下地压显现有明显加剧的趋势，在下一步92号矿体大规模开采时，地压问题将越来越严重。

Detailed description has been given individually to the abnormal colours, lineament and circular structure and image features on the multi-geographycal information composite image. We have studied the ore control effect of circular and lineament structure to the multimetal ore, and come to the point that the Xianghualing region is a complex ore control area by circular and lineament structure.Therefore, we build a remote sensing imag model for ore field in the region. Within the circular structure, the northwest lineament crosses the northweast lineament and forms frames that control the metal ore distribution. According to the features of the found deposits and their coherent image, we conclude that there are two symbols for ore looking.
