The Geochemical Characteristics Of Stream Sediments And Prospecting Direction In Huai'an,zhangjiakou Area

Zhangjiakou huai 'an area belongs to the northwest edge of north China platform,tectonic in Yanshan fold belt and shanxi lung interchange. Study area on the east side of shannon type synclinorium pagoda concave fold beam, the west side of town is five sets of dome of day town stage dome. The study area is an important metallogenic of northern north China plate, has good ore-forming geological conditions.The important structure of the study area is north west fracture and nearly east-west fracture, followed by the north west, north east to small faults, folds on a smaller scale.Tectonic movement was one of the major research area of mineral formation, by controlling the magmatic activity and movement form various properties of fractures and faults, control characteristics such as shape, size and distribution of the ore body, resulting in the formation of advantageous minerals of all kinds of structure forms.In the study area to 1:50 000 geochemical measurements, analysis summarizes the characteristics of a total of 19 kinds of single element anomalies and distribution. Au, Ag,As, Hg, Sb, and W element anomaly, a relatively large area. Sn, V, and zinc element is obvious anomalies. Other element anomaly area is relatively small, irregular distribution.Determined by multivariate statistical analysis of element, mainly in the study area is divided into six groups of combination anomaly 1?Ti-V-P-Sn-Co-Zn2?Hg-As-Sb-W3?Ni-Cr-Co4?Pb-Cd-Ag5?Bi-Mo6?Au. Of Ti-V-P-Sn-Co-Zn combination and Ni-Cr-Co combination of comprehensive anomaly is most significant, abnormal area is relatively large, clear zoning, is the main metallogenic province; Hg-As-Sb-W combination,combination of Pb-Cd-Ag, with the exception of the Bi-Mo area is relatively small, that its zone is important metallogenic province indicates more area. Au anomaly area is relatively small, but abnormal obviously, and the abnormal distribution range and metallogenic target collocated.Prediction research value larger area two mineralization target everywhere, located in the northwest and southeast of the study area. Target and mineralization has good mineralization conditions, geochemical anomalies, combined with field survey results and other geological data, geophysical and geochemical data can be drawn from the target area has a promising gold ore, nickel, titanium, cobalt and other metals.
