冀北新杖子地区水系沉积物地球化学特征及找矿预测

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

摘要

摘要: 提要: 冀北新杖子地区位于阜新—集宁成矿带的张家口—承德成矿区东北部, 具有较好的找矿前景。在全区1∶50000水系沉积物测量基础上, 对区内地球化学特征进行了初步分析。本文综合研究元素地球化学特征参数、元素R聚类相关性、单元素异常特征及因子分析表明, Au、Ag、Cu、Zn、Pb等元素具有一定的找矿潜力; 依据水系沉积物异常圈定、筛选、评序及主要异常解释推断的成果, 结合区内成矿地质构造背景, 进一步圈定出石湖金矿、潘家店金矿、路通沟多金属矿和荣家庄多金属矿4个远景区。

Abstract: 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.
