Mineralization Comprehensive Evaluation System based on remote sensing is a new exploration system of recognition,identification,analysis and prediction.It takes metallogenic materials as the detection targets,uses the spectrum measuring technique as detection means and takes the spatial and temporal sequence of mineralization and alteration information as an evaluation basis.It develops and improves the traditional mineral exploration technique of remote sensing.Based on this mineral exploration system,we develop new algorithms,set up relevant software platforms and carry out a series of study of application techniques of remote sensing.During the study of porphyry copper in West Dzungaria,structure interpretation,rock body recognition and altered mineral mapping were accomplished and alteration zoning and mineral exploration model were set up with this system and the target enclosing was completed with the model which was validated by the field work.Practice shows that the Comprehensive Evaluation system of remote sensing is indispensable in the integration of sky-ground remote sensing.It is an effective method of the truth examination of mineral remote sensing products.It is also effective in the implementation of spot-plane interaction and scale transformation.It has the characteristics of quantitative analysis and high precision.It plays an important part in the mineral prediction,target area evaluation and mineral exploration.
