福建大田—一都弧形构造遥感影像特征及其地质意义

本文利用卫星遥感影像数据进行线性构造解译,分析了福建大田—一都弧形构造及其对应的弧形影像特征,认为该弧形构造是在永安—晋江断裂带右行扭动作用下形成的；弧形构造及其特殊影像纹理特征具有表明断裂性质、判断不同方向断裂带发生先后次序的作用；弧形影像与其他断裂构造形成的线性影像叠合特征对指导找矿有重要意义.

Characteristics of remote-sensing image and geological significance for the Datian-Yidou arcuate structure in Fujian Province

Using the satellite remote-sensing image data and the method of linear structural interpretation, this paper analyzes the characteristics of arcuate structure and corresponding arcuate image of the Datian-Yidu arcute structure in Fujian Province. It is considered that the arcuate structure was formed by the action of right-lateral wrench movement of the Yong＇an-Jinjiang fault zone. The arcuate structure and its special veined image texture features can indicate the properties of faults and assess the action sequence of fault zones in different directions and the characteristics of congruence of arcuate image with liner images resul- ted from the other fault structures have an important geological significance for ore prospecting.
