| Comprehensive information mineral estimate prospect predicts based on geological theory,used the information of geophysical,geochemistry and geology remote sensing etc. to carry on estimate work.It fixes attention on geology conditional analysis that formed mineral and the research of mineral marking at the mineral bed and the summary of the mineralization rule.As a result,it has greater objectivity and function.Magnetic exploration is a geophysical method through observing magnetic difference in the underground medium.It can be used to find rock bodies who has magnetic anomalies and other earth burial.Now it has been used in magnetite exploration,regional geology exploration,underground geothermicsource,underground metal tubal and lines,underground bomb unexploded,wasted metal and archeology more and more widely.With the improvement of instrument precision and development of inversion,people pay more attention to magnetic exploration.Longchuan Country ,Guangdong Province fold in the South China within the department of Heyuan deep fault zone and Guidong deep fault zone handover of southwest uplift,where is one of the important countrynon-ferrous metal and sulfur mineralized zone.Jinshizhang mining zone has good geological condition and notable mineralization marks,so it has prospect of seeking large size lead-zinc silver deposits.This paper depends on high-precision magnetic survey by China Non-Ferrous Metals Resource Exploration Co. LTD, Changsha.,analysis magnetic anomaly in Jinshizhang district.The district has 3 magnetic anomaly belts and 17 magnetic anomaly spots.This paper delineate anomaly shape and define its stike and plane location by reduction to equator,derivation and analytic signal method.At the same time,combining geological pre-exploration and geochemical data,this paper make Comprehensive information mineral estimate.It gets 3 prospecting targets, 2 mineralization zones and 8 faults. Thus,it fulfill the target of optimization mineral exploration.
