Taoling Pb-Zn orefield was thoroughly investigated by many geologists since 1950’s However

there are many different ideas about the ore-controlling regularity. In order to probe the effectiveness of ore-finding with the remote sensing technique

based on predecessors’ work

the studies on the characteristics of the geological structures and ore-finding prospects

have been made with the aid of the digital processing images of remote sensing

and a good result have been achieved.The processing of images was carried out in the IPOS/101 computer. The processing contents include geometric restoration and correction

colour enhancement

contrast stretching

frequency enhancement

algebraic calculational enhancement and non-controlling classification

etc.. More than 10 methods

compound

ratio

convolve

fourier transform

cluster analysis

were adopted

and 33 images were obtained.By the interpretation of digital processing images

the linear and circular structures can be obviously determined

therore-controlling characteristics of faults can be intuitively found

and the favorable ore-finding areas can Be located. All of these provide some important re-ferrentia1 information about exploration for minerals.
