     本文在充分搜集了区域以往地质、物探、化探、矿产勘查等资料的基础上,对研究区内的金矿成矿地质背景、地球物理条件、地球化学条件进行了全面、系统、完整的分析,获取了大量的有用信息。通过典型矿床研究,建立起与研究区地质环境相应的金矿成矿模式,以典型矿床为目标研究了各种信息的关联关系,进而建立起该区的综合信息找矿模型。以成矿规律、成矿控制和找矿模型为指导,在区内过行了统计地质单元的划分,划分出44个统计单元;在找矿模型定量转换的基础上,选用了多种预测方法构建了金矿资源的定位、定量评价模型,并进行了科学预测。通过预测结果的解释,在研究内确定了一级找矿远景区3个,二级找矿远景区5个,分布在3个成矿带中,预测全区金矿资源潜力153吨。编制赤南地区的金矿资源分布图,并对一、二级找矿远景区提出工作布署建议。研究成果对赤峰南部地区今后找矿勘探工作具有重要的参考价值。
Northern margin of north china platform is an important metallogenic belt for non-ferrous metals and precious metals, and one of 16 key minerogenic belts for solid mineral resource in China. South of Chifeng is the important component in this mineralization belt.This area occupies the connection spot of northern margin of north china platform with the Mongolian geosyncline orogenic zone.Geological structure in the area is complex,the activity of magmatic is frequent,the deterioration distortion function is obvious.The mining history is glorious,the geological condition of mineralizing is superior,where is the advantageous sector for precious metal,and polymetallic minerals. besides, the gold ore is the superiority ore to plant.
     This article taking the modern metallogenic theory as the instruction, conducts the research for the first time in the area using the synthesis information minerals prediction technique. We will use the synthesis information minerals prediction technique to analyze the regional geology, the geophysical prospecting, the geochemical exploration and the minerals investigation material, thus will get some new knowledge form the excavation and the connection from the information. the next step will Conduct the research and the appraisal to the region minerals resource,finally,for the units selected, we will make geological interpretation and put forward the proposal to deployment the prospecting work.
     1、Fundamental geology
     This area has the glorious gold mining history, in addition to,new metallogenic theory and new method has been used widely in recent years.which has led the mineralization analysis more and more detailed.There are many kinds of mineralization concepts in a long period,which has made tremendous contribution to the metallogenic theory's consummation.But the fundamental of mineralization has not changed obviously.The first source bed unification understanding was the Pre-Cambrian Period antique generation of deterioration rock mass,The second source bed was the Paleozoic Era later period to the Mesozoic Era early time original rock restoration activation magmatic rock;the metallogenic model can been unified for the original rock restoration and the superimposition concentrates function.In view of the minerals forecast,the metallogenic model will be called as compound endogenous model.
     The tectonic framework in south of Chifeng area are mainly controlled by the Chifeng-Kaiyuan breaks and the Nenjiang-Qinglonghe breaks these two first-level structure.These two first-level structures are the basic tectonic element in the area.These structures is controlling the distribution of second-level structure and the fluctuation of fault block in the area,and which is in charge of the Heilihe-Yebaishou breaks,the Xiaoniuqun-Jiefangyingzi break and the Jinshan-Chifeng break and so on,these secondary breaks were controlling the Paleozoic Era to the Mesozoic Era intrusive rockthe alteration beltthe deterioration distortion belt's spatial distribution and the spreed form in the area.Gold deposits in the area is mainly affected by the spatial distribution of cross-cutting between NE and EW faults,thus the EW faults and NE faults and the intersection location is the most potential ore-forming tectonic environment.
     2、Geochemical conclusions
     Studies 39 kinds of elements in the region,pick up 14 kinds of elements related with the gold mineralization after the geochemistry research.Studies 14 kinds of element statistical parameter characteristic,which pointed out that the region elements are deficients primarily,but the discreteness of these elements is big enough,which noted that the regional metallogenic Events is dramatic,so the enrichment of ore-forming element makes it possible for mineralization.The multivariate statistical analysis shows that the area with the characteristics of multiple phases of superimposed mineralization.Based on the analysis for geochemical field,the study area will be divided into three types of geochemical field,the geochemical element of I-type are related with mineralization.Other two kinds are element related with mineralization and tracer element.The combination anomaly are divided into three types,the combination anomaly of Au-As;the combination anomaly of Au-Ag and the simple combination anomaly,The research for the combination of abnormal suggest that those area where the content of Au is high in background and the discreteness is strong are favorable position for mineralization.Au-As type combination anomaly and Au-Ag type combination anomalies has certain relationship with gold deposits.
     3、Geophysical conclusions
     In this paper,we collect the regional physical information, based on the comparative analysis of those data set up the basic understanding for regional geophysical interpretation,which pointed out that there are big difference in regional rock (ore) on the physical properties,magnetic characteristics.Take the natural material as the foundation,carries on the analysis and infer the conditions related with the gold mineralization, such as tectonics,stratigraphyintrusive rocks.We make the interpretation to the regional tectonic using synthesis information interpretation principle and the method.The result shows that EW faults,NW faults and NE faults is extremely widespread,particular emphasis is the development situation of EW structures and the NW structures is relatively weak,which assumes off and on be in charge of the NE structure,these reflect the characteristics of multi-phase transformation,all the works consummate the system of regional tectonic.Through the analysis of the aeromagnetic field which reduced to the pole,the aeromagnetic field will be divided into 8 magnetic body,which we had make the geological explaination carefully.
     4、Research on typical deposit
     In this section,we summarized the ore-forming background,geological features,metallogeny and ore-forming characteristics about Mesozoic hydrothermal gold deposits and sub-volcanic rock-type gold deposit in south of Chifeng.The conclusion indicates that gold ore-controlling condition was mainly the Archean Metamorphic rockstectonic fracture systems and Yanshanian-hercynian intrusive rocks system.the analysis indicates that the uplift zone with distribution of Archean stratigraphic and volcanic activity Mesozoic basin and the edge of its interaction spot are the best parts for mineralization. Fracture NW direction and the intersection with the NE fracture and its associated secondary-fault zone are the best mineralization spots.The intersection spot of EW faults with the NW or SN faults and its vicinity with deep fault and shallow fault is the best parts for mineralization.The intermediate-acid intrusive rock in Mesozoic or Paleozoic period are favorable factors for mineralization.some ultra hypabyssal rock region where the intermediate-acid vein rocks is the main body,especially these ultra-hypabyssal porphyry vein with higher Au-Ag-Cu-Pb-Zn contents at Yanshanian to be more advantageous to the mineralization.At the same time,some region with wall-rock alteration,surface of the "burning skin" and the "face sesame",are the important spots for mineralization.
     This paper take the typical deposit research as the foundation,refer to the the system of tectonic evolution,has established a compound endogenous-type gold mineralization model which related with Archean metamorphic in south of Chifeng,the author has mapped the regional metallogenic model finally.
     5、Mineral prediction results
     Based on the research about metallogenic regularity and metallogenic model in south of Chifeng, a comprehensive prospecting model.is established Altogether selects statistical unit 44,in which the statistics unit with accurate reserves data is 13,unknown statistical unit is 31.
     While it carries on the regional prospecting work, established a set of method systematically according to the characteristic about mid-small scale synthesis information prospecting:the unit mineralization probability→the unit scale→the unit amount of resources→an entire area amount of resources.
     ①Location prediction
     Carries on the resources localization forecast according to the synthesis information mineralization prediction theory in the research area,the choice method include the characteristic analysis,the Q cluster analysis,the correspondence analysis and the quantification theory IV.Using these methods calculats the probability of mineralization separately,the statistical units will be divided into 4 level after analysed synthetically.In considered fully the structural environment and the unit distribution which has gold deposits or the probability of mineralization above B level,south of Chifeng is divided into three metallogenic belt.Three metallogenic belts respectively are Xiaoniuqun-Jiefangyingzi,Jinshan-Malan and Heilihe-Tianyi mineralization belt.
     ②Quantitative prediction
     In this section the author establish the forecast model for south of Chifeng using the logic information law,test the model with the verification units,get the confirmation rate of accuracy is 71%,it indicates that this method can be used for prediction on the unknown units,finally calculate the amount of resources 69.25 tons using the method.In the next section the author use the collection of ore unit with reserves to set up the multivariate linear regression equation,then test the regressioin equation with the significance test,finally forecast the amount of resource 153 tons.In the third section the author,set up regional resource prediction probability model: resource extent=number of deposits×ore reserves×ore grade with the Monte-Carlo law,then collect the ore reserves-grade data in Chifeng and its peripheral region,in final,calculat the amount of resources 215 tons with random sampling method.Through many kinds of methods and take care of adaption,we point out the resources of south of Chifeng is 153 tons.It noted that the area has potential for mineralization,there will continue to be an important areas for prospecting.
     In the overall evaluation localization forecast and under the quantitative forecasting result's premise,we take into account the conditions of ore-forming unit,choose 3 first-level prospecting area and 5 second-level prospecting area from 13 B-level unit,this work will provide some clues to geological exploration afterwards.
