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

摘要:

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。

Abstract:

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 p...
