甘肃北山古火山机构浅见

甘肃北山地区基岩裸露好, 古生代的火山岩系在区内广泛发育, 这就给用遥感技术寻找和研究古火山机构提供了有利条件。本文通过对北山地区卫星MSS像片、全色航空像片的解译, 阐述了锰铁山、黑鹰山古火山机构的形态、地貌、水系等遥感影像特征以及古火山机构与构造、矿产的关系。北山地区古火山机构的发现, 对类似地区用遥感方法寻找古火山机构及与古火山机构有关的矿产提供了例证。

THE SUPERFICIAL VIEW FOR OLD VOLCANIC MECHANISM IN THE BEISHAN AREA OF GANSU PROVINCE

The well exposed Palaeozoic volcanic rocks distribute extensively in the Beishan area of Gansu province,this provides favourable conditions for finding and studying old volcanic mechanism with remote sensing technique. By interpreting satellite images and aerial photographs of the Beishan area, this article elaborated the Meng-tieshan, Hei-yinshan old volcanic features including, the shape and land form as well as their relationship with geological structure, and mineral resources.
