高龙金矿区高分辨率遥感线性构造分形特征及综合成矿预测
|
摘要
利用分形几何学的原理和方法,结合目前全球分辨率最高的商业成像卫星——QuickBird-2高分辨率卫星遥感资料,对广西高龙金矿区遥感线性构造进行了定量研究。结果显示,在0.250～2.000km标度范围内,用盒计维数法求得的全区的分维值D=1.660,回归直线的相关系数R=0.999,且已知的鸡公岩、金龙山和龙爱三个矿段均落在分维高值区。研究表明,就整个矿区而言,近EW向线性构造较近SN向线性构造更为发育。提出了两个成矿预测区,并利用地球化学分析方法进行验证,取得了很好的成矿预测效果。
Based on the theory and methodology of fractal geometry,and integrated the data of QuickBird-2 --the highest resolution remote sensing(HRRS) business satellite in the world up to now,the authors have quantitatively studied remote sensing(RS) lineations in Gaolong gold deposit of guangxi.The Fractal dimension(FD)for the RS lineations on the 1.250~2.000km range of scale is 1.660,and the correlation coefficient of the regression line(R)is 0.999,three known ore blockes of Ji Gongyan?Jin Longshan and Long Ai are all in the area of high FD?The results indicated that the lineations of near EW orientation are more growth than the lineations of near SN.The article concluded two ore deposit prediction areas and validated with the method of geochemistry, the result is good.
