秘鲁阿雷基帕省阿蒂科地区水系沉积物地球化学特征及找矿远景预测

Geochemical characteristics and metallogenic prospective prognosis of Atico region in Arequipa Province, Peru, based on stream sediment survey

摘要: 依据1：10万水系沉积物测量资料，分析研究了秘鲁南部阿蒂科地区水系沉积物地球化学特征。通过对元素分布、元素相关性、单元素异常、异常元素组合等特征的分析，结合成矿地质条件，圈定了阿祖卡、塞罗皮耶霍、帕姆帕和卡拉帕尔卡4处找矿远景区，为该区下一步的找矿工作指明了方向。

Abstract: The study of geochemical features of Atico region in southern Peru was based on the 1:100 000 stream sediment survey. Through a study of the element distribution, element correlation, element anomalies and element anomaly assemblage, combined with the ore-forming geological conditions, the authors divided the study area into Azucar, Cerro Viejo, Pampa and Calaparca metallogenic prospective areas. The results obtained by the authors can play an important guiding role in further ore-prospecting work.
