武当地区遥感构造信息定量化分析

Quantitative Analysis of Remote Sensing Structure Information in Wudang Area

利用遥感构造定量分析方法,对武当地区线状构造的定量计算和分析,显示武当地区线状构造以小于100 km的中、小断裂居多;线状构造等密度、频度、交点数、中心对称度,均反映了区域主干线状构造主导方向为北西西和北东两个方位;北东向小型线状构造由北往南更加发育,推断武当地区由北往南,构造运动变新,构造变形由韧性往脆性发展;优益度的特高值—高值区提供了找矿预测的构造信息,对于矿产调查有较好的指导意义。

We conduct the quantitative calculation and analyses on Wudang area structure by remote sensing mathematical statistical methods.The work shows that the linear tectonic structure of the Wudang area is mostly the small and medium size fractures which are less than 100 kilometers long.The quantitative analyses of iso-density,frequency,intersection points and advantageous,reflect that the leading directions are NWW and NE.The NE direction fractures are more developed from north to south.It infers that the Tectonic deformation developed from ductile to brittle from north to south in Wudang area.The particularly high value-high value of the excellent benefits provide the structural information for prospecting prognosis.This has a preferable guiding significance for the further investigation of mineral resources in the area.
