遥感技术在东天山大黑山地区地质填图中的应用

Application of Remote Sensing Technique in the Geologic Mapping of Daheishan Region,Eastern Tianshan

利用不同地质体在同一波段或相同地质体在不同波段具有不同色调的变化规律,对东天山大黑山地区的ETM+图像和Spot图像进行了详细的地质解译,建立了研究区地层、侵入体和构造的解译标志。解译结果表明,在遥感影像图上可以准确的勾绘不同地质体的界线、确定不同构造的位置。通过野外地质调查,划分出不同的地层单位、侵入体和构造现象。遥感地质解译和野外验证结果对比表明,遥感技术在地质填图工作中可以发挥重要作用。

According to the color variations of different geological bodies in the same wave band or the same geological body in different wave bands,a close geological interpretation was made onthe ETM＋and Spot images ofthe East Tianshan orogen.As a result,interpretation markers for the strata,intrusive body and structures are established.The interpretation allows us to accu-rately define the strata boundaries and structures locations on the ETM＋ and Spot images.The strata and intrusive bodiesin the mapping area can be divided into different units based on the field survey.The structures including faults and fold can be identified in this area.It is believed that remote sensing image can play an important role in geological mapping.
