摘要
综合信息找矿模型是指在成矿模型理论先验前提下,从找矿(矿产资源体)的角度出发,总结客观存在的找矿标志、找矿前提及其综合信息特征,形成一种统计性的找矿模式,即综合信息找矿模型。其目的就是在建立综合信息找矿模型的基础上,通过直接找矿信息和间接找矿信息的关联和合理的信息转换,建立以间接找矿信息为主体的,适合研究区研究程度的综合信息预测模型进行预测评价。
    本文以地质异常和综合信息成矿预测理论为指导,选取云南鹤庆北衙富碱斑岩型金矿为典型矿床,综合运用地球物理、地球化学、遥感等现代勘查技术和手段,全面系统地研究北衙金矿各种有利成矿条件,找矿标志,在此基础上建立综合信息找矿模型,最后,基于综合信息找矿模型建立一种基于知识驱动的预测评价方法进行区域和矿区成矿预测。本文共分三部分七章。
    第一部分为第一章,是论文选题依据和理论基础。从综合信息找矿模型在现代矿产勘查中的重要作用和意义出发,结合云南富碱斑岩型金矿的研究现状,指出在云南滇西进行富碱斑岩型金矿综合信息找矿模型研究的理论和现实意义。
    进行综合信息找矿模型研究的意义在于:
    1、随着找矿难度增大,在寻找隐伏矿和难识别矿勘查工作中,综合应用地质、物探、化探、遥感资料进行综合信息成矿预测是现代地质找矿勘查的一种重要手段和必然趋势。
    2、矿产勘查又是一种经济行为,要求以较少的投入,取得较好的地质效果和较大的经济效益。基于成矿理论指导和找矿实践积累所建立的综合信息找矿模型是矿产勘查和资源评价的有效工具。
    3、综合信息找矿模型是有效地克服地质观察的不统一性和物化探的多解性,较全面地反映地质体和矿产资源体的客观面貌的有利工具。
    就云南省而言,滇西与富碱斑岩有关的金矿是云南省新发现的极为重要的金矿类型,其资源远景储量可达数百吨,但该类金矿的找矿工作起步较晚,勘查程度较低,金矿床(点)还处于成矿条件研究不够,资源量不清、成型矿床较少等现状。因此,选择典型矿床,从成矿预测角度,综合分析矿床的地质、地球物理、地球化学、遥感异常信息特征,建立一种适合矿区和区域找矿评价的综合找矿模型,为滇西北富碱斑岩型金矿的快速高效找矿评价提供科学的评价模型和评价方法,无论在理论上还是实践上都有重要意义。
    第二部分包括第二、三、四、五、六章,是论文的主要研究内容,也是综合信息找矿模型研究的中心内容。论文第二、第三章详细探讨了北衙金矿床的区域成矿背景和地球物理场、地球化学场特征。研究表明金沙江-哀牢山断裂、程海断裂等深大断裂控制了斑岩
Integrated information prospecting model is to summarize the mineralized indictors,exploration precondition and comprehensive information characters with the precondition of mineralization theory, ore body and then come into being a statistical exploring model.It aims to establish an integrated model suited for the research degree and geological setting to predict and assess mineral deposits by the information correlation and conversion between direct and indirect mineralization indictors on the base of constructing comprehensive information prospecting model.
    This thesis studied the mineralization indictors,favorable condition systemically and then established the integrated information exploring model guided by comprehensive information minerals theory through applying geophysical,geochemical and remote sensing technologies in a typical alkali porphyry gold deposit in Beiya,Heqing county of Yunnan province.A knowledge-driven based predict method on the base of integration information prospecting model was established.This paper is composed by 3 parts or 7 chapters.
    The first chapter is the theory basis and foundation of the research title.The realistic and academic signification applying integrated information model in this alkali porphyry gold deposit in western Yunan were stated from the view of comprehensive information model in modern exploration combined with the study status of this deposit.
    The signification of applying integrated information prospecting model is:
    1.With the increasing of difficulty in deposit exploration,applying geological,geochemical and remote sensing data synthetically is an important and certain trend in exploring insidious and hard identified ore deposits.
    2.Minerals exploration is also a economical activity which calls for better geological effect and bigger economical benefit.While the integrated information exploring model is the effective tools for minerals exploring and resource assessment which is the result of minerals theory and practice development.
    3、The integrated information exploring model is a favored tool to overcome the disuniform in geological observation and multi-interpretion in geochemical and geophysical data,which is also can reflect the external visage of deposit and minerals.
    As to Yunan province, the new gold deposit related to high-alkali porphyry in the western regions of the Yunan Province is the extremely important gold mine type of the new discovery, its resource perspective reserves can up to several hundred ton. However, the ore finding work about this type of gold deposits is just started, the exploration is poor, and the study of its
    mineralization condition is still need more work, reserve is uncertain and the deposit is less. So, it is more significant no matter in theory or on practice to select the representative deposits, combine and analysis its information about geology、geophysics、 geochemical and remote sensing, and then form a final deposit researching model. Second part including two, three,four,five ,six chapters, is the main research contents of the thesis, it is the centre point that the integrated information looks for the ore model and studies too. The regional mineralization background, geophysical and geochemical character of Beiya gold deposit are detail discussed in chapter tow and chapter three. The final study shows that Jinshajiang-Ailaoshan faults and Chenghai faults controlled the distribution of the porphyry cluster and deposit zone, regional faults and its conjunction area controlled the deposits distribution. The high-alkali porphyry has more consanguineous relationship with regional gold deposits both in time and spatial. Regional magma activities have a character of multi-epoch and multi-stage. Fastigium of mineralization enrichment is in the middle stage of magma activities. And the area with complex massif is more favorable place. Trace it to its cause, first, necessary hot motive force gets the supply continually, second, perhaps the offering mineral substance continually. The characteristic of regional geophysics field, geochemistry field shows that the gold mine of Beiya is in the regional aeromagnetic slow unusual range of negative value, reflects that this district is a ground body of basin. The aeromagnetic value of NE and SE is normal, The aeromagnetic unusual value of the NE gradient band existed in the SE side possible reflects the dark rupture. At the same time, the gold mine of Beiya located in the NE abnormity grads band of average gravity, and located in the south positive unusual edge where the negative abnormity cut off the positive abnormity in north and south. So, the obvious change terrain of the two kind of geophysics field, gravity field and aeromagnetic field is the signal of regional geophysics related to rich alkali and porphyry that rich gold and metalliferous deposit distribute. 1:200,000 river system sedimentary gold and relevant element content and unusual characteristic indicated that rich alkali porphyritic ore terrain often have obvious concentrated center of Au unusually, and accompanied with the unusual combination of Ag, Pb, Zn, and As at the same time. The mineralization model is the bases of Integrated information prospecting model and its credibled base on the research of mechanism of metallogeny、metallotect and ore guide.The geology feature、mechanism of metallogeny、metallotect、Integrated prospecting of geophysics and geochemistry is studied in the fourth chapter and fifth chapte.Sum up the ore-control feature by structure-magma-mineralization of Beiya gold mine.There are three typies of gold mine:the gold-ieon mine related of alkali porphyry、laterite gold deposit、drift bed gold deposit。By the study of suifur and isotope it inditade that the gold come from the upper mantle and mineralization go up from earth deepness with the hydrothermal fluid of the alkali porphyry.The alteration feature is potassic-silicium-ferrum from the rock core to contact strip.Establish the Integrated information prospecting model of Integrated information prospecting model base on the geology feature、mineralization types、mineralization source mineralization.The prospecting sign of geophysics and geochemistry: 1、middle-strong magnetic anomaly and consistent the
    regionality constract trend; 2、low-slow ortho and negative magnetic anomaly ang has low electric resistance; 3、high Au and Au—Pb—Ag anomaly。 Geology active、mineralization、hot-dynamica action has reflex by heating power field、geochemistry、geophysical、structure stresss and mineralization field.we can acquisition the usefulness information of string-ring structure and alteration from remote sense.. From some sense,remote sense information is the outside represent of Integrated mineralization information.Acquisition the high resolution color composite image Base on the teature of ground object spectrum and ETM1~5、7 与 ETM8 fusion. Acquisition the limestone stratum by SAM and string-ring structure base on the imagefeature. Its difficulty to detail recognize alteration with ETM image.Estabish the Ratio +selected PC+HIS emphasis extract model of alteration information .Base the model, Acquisition the alteration information in study field. The third part sets up the integrated information exploring model for alkali porphyry gold deposit in Beiya based on the second part which researches in detail on regional geological background,regeional geophysical field, geochemical characters,geophysics of the diggings,geochemistry,remote sensing anomaly information characters and deposit geological characters.The integrated information exploring model based on deposit metallogenic pattern integrates the mineralization rule knowledge with exploring favorable information on the exploring targets.In fact,the regional mineral resource prediction and evaluation based on the integrated information exploring model is a mineral resource quantitative evaluation way based on knowledge drive,which selects and evaluates the predicting variables by the knowledge gotten from the integrated information exploring model.The paper establishes a modifiable and two types evaluating way to give the variable’s value.The process classifies the 12 variables into 3 classes named Ⅰ ,Ⅱand Ⅲ according to the integrated information exploring model and gives them respectively 1.0,0.5,0.2 weights.At last,using the spatial analyses function and characteristic information way,the regional mineral resource prediction and evaluation is done,then the future regions are forcasted.The results are as follows: the first class future region has one named Wayao-Beiya-Nandaping,the second class future have three named Taipingcun-Changmujing-Heinishao,Changping-Malachang and Gaomei-Dabanjing. When the region prediction is done,the four exploring target regions are forcasted using integrated information and deposit mineralzation prediction. The four exploring target regions are named respectively Wangdongshan East-west contacting zone,Hongnitang rock east contacting zone,Bijiashan west contacting zone and Tertiary and Quaternary zone in Beiya basen.
