In plateau shallow hill area of northern Sichuan,stream sediments are characterized by low geochemical background,weak anomalies with insignificant gradient,and indistinct ore prospecting indicators,and hence it is quite difficult to carry out ore prospecting work in this area.Based on systematic summarization of geochemical characteristics of this area,the author conducted sieving and inspection of anomalies and obtained fairly satisfactory ore prospecting effects and experience.
