Geochemical characteristics and prospecting prospect of stream sediment in the Sandaolazi-Cuocaodingzi,Jilin Province
As an important means of geochemical survey,the 1∶50 000 stream sediment survey has been widely used.The 1∶50 000 stream sediment survey is carried out in the Sandaolazi-Cuocaodingzi area,aiming at delineate anomalies.Through the inspection and evaluation of anomalies,the prospecting target area is delineated,and then the prospecting area is further divided,and mineralization prediction is made.Based on the original measurement data of 11 elements measured of the stream sediment in the area,the distribution and characteristic parameters of elements in stream sediment are statisti-cally analyzed.The enrichment and dispersion rules,element combination characteristics and their relationship with metal-logenic geological conditions are summarized.Combined with the metallogenic geological conditions and geochemical char-acteristics,24 comprehensive anomalies have been delineated,3 prospecting areas have been divided,which have great mineralization potential.This has pointed out the direction for the optimization of various non-ferrous metal mineral target areas,resource potential evaluation,and the next geological prospecting work.
