前言虽然早已对安大略东北部波丘潘矿区含金石英脉与风化的铁锈色碳酸盐蚀变岩之间的紧密关系作过总结(图1),但对蚀变作用与构造地质学和地层学的关系很少加以论证。科尼奥尔慕矿属于霍林格—麦克因蒂尔矿化带的北东延伸部分,含金石英脉(主要产在碳酸盐蚀变岩中)在地表出露很好。 1983年间,在科尼奥尔慕矿区由高级人员建立座标网,并进行了详细地质填图(图1),以确定碳酸盐蚀变带的时限和控制它的构造-地层因素。以后对近100个样品进行了岩石学研究,以确定碳酸盐蚀变与穿透构造组构的关系。本文是基于野外工作和野外岩石学方面的研究。
Foreword Although the close relationship between the gold-bearing quartz veins in the Bunchiumpan mines in northeastern Ontario and the weathered altered rust-colored carbonate rocks has been summarized (Fig. 1), alteration and tectonic geology and stratigraphy The relationship between science is rarely justified. The Koenigmühn deposit belongs to the northeastern extension of the Hollinger-Mickindl mineralization belt and gold-bearing quartz veins (mainly found in carbonate altered rocks) show well on the earth’s surface. In 1983, a coordinate network was established by senior staff in the Koenigmud mine and detailed geological mapping (Fig. 1) was conducted to determine the timing of the carbonate alteration zone and the tectonic-stratigraphic factors that controlled it. Nearly 100 samples were later petrologically studied to determine the relationship between carbonate alteration and penetrating tectonics. This article is based on field work and field petrology.
