It is very abundent for lead-zinc polymetallic deposits in Lanping area

Yunnan

where there are large scale lead-zinc deposites. Digital image processing was given in this paper

aimed at the study of the structures of controlling rocks and ore deposites which are concerned with the lead-zinc polymetallic deposites in this area. Its major processing functions are as follows: contrast enhancement

ratio synthesis

KL-trasformation and spatial convolution

etc.

which was made out by the M-70 image proessing computer of SIOI system. Treated results show that there is plenty of imaging tones and laminated textures

and a great deal of information of geology and ore. Combined the geological conditions of the area with the genetic relations of the information of linear structures

circular structures

color anomalies

etc.

and the known ore deposits

mineralizd points

geophysical and geochemical anommalies

auther make a calculation on mineral resources. The results show that there are six metallogenic belts

ten prognostic metallogenic prospect provinces and fourty-two prognostic mineral occurrences in the study area. Among those there are twenty Ist-order prognostic mineral occurrences and four Ist-order prognostic metallogenic prospect provinces. After inspection for some prognostic points

auther find two lead-zinc mineralizations.
