【摘要】 Pine Creek造山带中部地区是北领地三大金矿矿集区之一,区内金矿床/矿点主要有三种类型:a)石英脉型金矿,b)条带状铁质岩相关金矿,c)金—多金属型金矿。本文通过梳理金矿床/矿点数据库,分析各类型金矿床/矿点的分布情况以及典型矿床的地质特征,总结了各类型金矿的空间分布与地层、构造、岩浆岩的关系,矿化局部富集规律等。更多还原

【Abstract】 The central Pine Creek orogenic belt is one of the three major gold deposit clusters in the Northern Territory.There are three main types of gold deposits/occurences in the area: a) quartz vein type gold deposits, b) banded ironstone-related gold deposits, c) gold-polymetallic type gold deposits. By using the database of gold deposits/occurrences, this paper analyzes the distribution of various types of gold deposits/occurrences and the geological characteristics of typical deposits, and summarizes the relationship between the spatial distribution of various types of gold deposits and strata, structures and magmatic rocks, as well as the regularity of local mineralization and enrichment.更多还原
