| Abstract: | Remote-sensing method was applied in 1: 50000 scale geological mapping in Archaean metamor-phic complex in Northern Liaoning province. By the reference of aeromagnetic information, it has provied advanced geologic information and higher efficiency to surface work. With the add of remote-sensing interpretation, we have achieved a higher mapping quality and research level.Archaean metamorphic complex can be subdivided into tow types of image-geologic units in image , one is metamorphic supercrustal rock unit in which colourhue, water system and landform appear in linear stretch, the other is metamorphic plutonic mass unit in which the image demonstrates a circular pattern. The inner circular structure which indicate plutonic genesis can be interpreted fairly well. The linear lamination belts which caused by anomalous micro-landform can be better interpreted as ductile shear zones or strongly developed gneissosity belts.From all above, we can see that remote-sensing interpretation has played an important role in mapping in middle-high degree metamorphic terrain and should not be neglected. |
