| The Bor region of Serbia has a long history of mining and abundant mineral resources.It has been the European mineral resources mining center since the beginning of the 20 th century,and existing researches shows that there are still massive mineral resources undiscovered.Serbia is the main cooperation object of the " Belt and Road Initiative " in the Nordic countries of China.In response to the call of the country,this paper takes the Bor area of Serbia as the research area,analyzes the characteristics of remote sensing structure and summarizes the regional metallogenic regularity according to the existing data,and provides remote sensing basic data for the next geological prospecting and exploration work.In this experiment,the linear structure and circular structure of the study area were interpreted by multi-source remote sensing images enhanced by data integration and color composition.Step by step analysis of linear structure orientation,statistics,length density,fractal characteristics;ring structure space,geological genesis characteristics;line ring structure combination space,intersection density characteristics.Combined with the spatial combination relationship between regional endogenetic metal deposit,ore(mineralization)points and linear structures and circular structures,the regional metallogenic regularity is analyzed.Summarized the remote sensing geological characteristics of typical deposits.Based on the analytic hierarchy process,the remote sensing geological prospecting model of endogenous metal deposits is established to predict the favorable areas for prospecting.The results show that there are three groups of linear structures in NNW,NNE and EW directions in the study area.The NNW structure is the main structure,and the three groups of structures have multiple triangular style spaces.The high value area of linear structure density distributes in NNW direction;the overall fractal dimension value of the study area is 1.8558,which is a tensile strike-slip tectonic environment.The fractal dimension characteristics can directly reflect the comprehensive characteristics of the fault structure in each sub-region.The annular structure is distributed in NNW direction as a whole,and two NNW-trending and two NNE-trending belts are developed,which are jointly controlled by NNW-trending linear structure and NNE-trending linear structure.Geological genesis can be divided into magmatic activity and tectonic origin.Combined with the spatial distribution characteristics of endogenous metal deposits and ore(mineralization)points,it is found that the deposits and ore(mineralization)points are mostly located on both sides of the NNW-trending linear structure,the NNE-trending linear structure interval zone,and the linear structure intersection triangle.The ring structure has obvious control on the distribution of deposits and ore(mineralization)points.The high value area of linear structure density(> 3.31),high value area of fractal dimension(>1.568)and high value area of line-ring intersection density(>0.745)have good spatial coupling with ore deposits and mineralization points.Based on the analysis of remote sensing structural characteristics and the research results of metallogenic regularity,taking Bor deposit as a typical deposit,a remote sensing geological prospecting model of endogenous metal deposits is established based on analytic hierarchy process.With the relatively high value area of predicted value(> 1.086)as the standard,five favorable prospecting areas(I-V)are delineated.Through the verification of Jelenkovic ’s published ore point data,it is found that there are 27 deposits and ore(mineralization)points in the favorable target area of No.I,and 9 deposits and ore(mineralization)points in the favorable target area of No.II;there are 7 deposits and mineralization points in No.III favorable target area;there are 7 deposits and ore(mineralization)points in No.Ⅳ prospecting target area.There are 13 deposits and mineralization points in the No.V deposit.It further shows that the remote sensing prospecting model of endogenetic metal deposits proposed in this experiment is reasonable,and the high value area of predicted value(> 1.086)can be used as one of the predictors of ore-forming area. |
