Geochemical characteristics of stream sediments and metallogenic prognosis of Xinzhangzi area, northern Hebei Province

Abstract: Located in the northeast of Zhangjiakou-Chengde metallogenic ore district along the Fuxin-Jining metallogenic belt, the Xinzhangzi area shows a good ore-prospecting potential. Based on the 1∶50000 stream sediment survey, the authors primarily investigated the geochemical features of Xinzhangzi area. Element parameter study, R mode cluster analysis, factor analysis and element anomalies show that the study area might be a prospective area for Au, Ag, Cu, Pb and Zn. Combined with the metallogenic background in the aspects of strata and structure, the authors summed up the work of lineation, selection, ranking and interpretation of geochemical anomalies, and then delineated Shihu and Panjiadian gold metallogenic prospective areas as well as Lutonggou and Rongjiazhuang polymetallogenic prospective areas.
