化探方法模块组合在矿产勘查中的应用研究
|
摘要
随着现代分析化学学科的发展和新型仪器的研发,化学元素的测量范围和精度都有了明显的扩大和提高,利用先进的测试仪器,有选择性地选择现有的化探方法进行有机地结合,一种以求达到快速、准确、经济、高效等目的的综合性方法模块组合应运而生。
内蒙古赤峰市杨树林银多金属矿普查区位于内蒙古地轴东段与内蒙海西褶皱带接触带向北突出弧形的地轴东侧,属地轴Ⅲ级构造单元。地层走向受区域构造运动的控制,区内赤峰——铭山大断裂、初头朗——铭山断裂两侧所派生的断裂构造极为发育。
本文选择内蒙古赤峰市杨树林银多金属矿普查区为研究对象,通过氡气测量对研究区的断裂构造进行定位；使用X-荧光仪分析出露基岩、地表蚀变带、破碎带等相关地质体的元素含量以确定可能的成矿元素及有利成矿位置,初步圈定元素浓集中心；同时,利用有机烷烃气体测量的结果圈定有机气体浓集中心,最后综合确定可能的矿化部位,最终形成方法模块。
该方法模块的应用取得了较好的效果。测氡结果指示研究区内有数条隐伏断裂构造；X-荧光分析结果表明,研究区内Ag、Cu、Pb、Zn和Au为可能成矿元素,花岗斑岩,中粒、中细粒二长花岗岩,接触带,破碎带为有利成矿位置：有机烷烃气体测量的结果显示,在接触带出现浓集中心,对应有Ag、Au浓集中心出现,这表明,研究区有机烃气体异常能很好地指示接触带位置,并且能很好地指示Ag、Au元素的成矿位置。
为了验证方法的有效性,采用传统化探方法中的土壤地球化学测量加以对照验证,土壤地球化学测量Ag、Cu、Pb、Zn、Sn、Sb等10种元素,通过对比,结果基本一致,且方法模块的结果具有双重保证性,在综合考虑各因素后,共计圈定出7处成矿远景区。
研究结果表明,根据不同的景观条件将不同的化探方法揉合在一起,形成方法模块组合进行找矿,不仅其结果可相互验证,而且能更准确地获取更多的有用信息,大大地提高了化探方法在找矿中的精度和速度,是一种综合、快速、经济、高效的找矿新方法。
With the development of modern analytical chemistry discipline and the research and development of new apparatuses, measuring range and accuracy of chemical elements has been distinctly expanded and improved. Advanced testing apparatus was used and existing geochemical exploration menthods was combinied selectively, a new method with the purpose of fast, accuracy, economical, highly-efficient is to come into existence as the situation requires.
The prospecting area of the silver polymetallic ore of Yang Shulin in Chifeng Inner Mongolia located the extrude arc northward eastern side of the axis extrude arc where the zone of contact of the eastern of Inner Mongolia earth axis and Inner Mongolia Hercynian fold belt was selected as study area, and was gradeⅢstructure unit. Stratum strike is controlled by the regional structure movement, inside the area, fracture structure derived by the both sides of ChiFeng-Ming mountain geofracture and ChuToulang-Ming mountain fracture are greatly developmented.
In this paper, the prospecting area of the silver polymetallic ore of Yang Shulin in Chifeng Inner Mongolia was selected as study area, the fracture structure of study area was located through the measurement of radon gas, exposed bedrock, surface alteration zone, fracture zone and other related geology bodies were tested by using XRF analyzer, which could determine the possible metallogenic elements and favorable mineralization location, contoured the concentration center of elements and interpreted them, at the same time, the concentration center of organic gas was contoured with the results tested by organic alkane gas measurement, and then verify the structure and the abnormity of general elements preliminarily.
The using of this method made preferable purpose. Radon measurement results indicated that there were several lie concealed fracture structure in study area; the test results of XRF analyzer showed that Ag, Cu, Pb, Zn, Sn, Sb and Au element may be the metallogenic element, granite porphyry, medium-grain and fine grain adamellite. the contactive zone of layer and lithology taken change and the rupture zone of structure were favorable position for mineralization; organic gas phase geochemical exploration results indicated that the contactive zone of layer and lithology taken change appeared concentration center, corresponding to the emergence of Ag. Au concentration center, which showed that in study area using the organic gas phase geochemical exploration can well indicate changes of layer and lithology and the mineralization position of Ag, Au.
In order to verify the effectiveness of this method, the secondary halo of conventional methods was used to be contrasted, Ag, Cu, Pb, Zn, Sn, Sb, such as 10 kinds of elements were tested with geochemical soil survey, after contrast, the results are essentially consistent and the result of method modules has dual guarantee, after considering various factors, confirmed seven perspective mineralization area.
Comprehensively analyse the above-mentioned geochemical methods, and blend them together to form method modules combination, their results can be validated one another, and can infer more better useful information accurately, greatly improved the accuracy and operation of geochemical methods in the process of finding mine. Module combination method is a new method to comprehensively, rapidly and effectively find mine.
