山东栖霞地区金、银矿床类型及找矿方向

TYPES AND PROSPECTING DIRECTION OF Au-Ag DEPOSITS IN QIXIA, SHANDONG

本文根据笔者在本区的找矿实践,将区内金、银矿床划分为石英脉型、蚀变岩型和砂金矿床三大类,并进一步分为11个亚类,文中对其主要特征进行了总结。在总结区域成矿规律的基础上,分析了本区成矿条件,认为本区为金及多金属成矿区,特别对银矿普查更为有利。在找矿方向上将本区划分为四个金矿远景区和两个银矿远景区。

Based on his own exploration experience in the area, the author divides the Au-Ag deposits there into three broad types of quartz vein, altered rock and gold placer, and further divides them into eleven subtypes, whose major characteristics are herein summarized. The ore-forming conditions of the area are analyzed in the light of the summary of the regional metallogenic regularity. The region is held as a gold and polymetallic metallogenic province and especially favourable for exploring Ag deposits. Four prospective Au ore districts and two Ag ones have been delineated in the area in terms of prospecting.
