引言赫姆洛金矿床的独特地质特征和经济意义,已引起世界上经济地质学家的关注。本文介绍有关泰克-科罗纳矿区地质的总看法。其根据是1:1200的地表填图、近250个钻孔记录、大量的岩石学工作和代表性样品的化学分析资料。泰克-科罗纳矿区占地277.6公顷,位于加拿大安大略中北部的马拉松(Marathon)镇东35公里处。1947年在该矿区发现金,1945—1959年间,在当时认为是被剪切的长石和长石-石英斑岩中圈定了一条有矿石80750吨、金品位为8克/吨的矿带。1960—1980年间,产在横贯加拿大公路(17号公路)下的矿床,周期性地被勘查者和采矿公司用木桩标着进行勘查和废弃。1981年1月,科罗纳资源勘探有限公司开始对该勘查区进行详细
Introduction The unique geological features and economic significance of the Helmut gold deposit have attracted the attention of economic geologists in the world. This article presents a general view of the geology of the Tektronix Corona mining area. It is based on surface mapping of 1: 1200, nearly 250 borehole records, extensive petrographic work, and chemical analysis of representative samples. The Tektronix-Corona mine covers 277.6 hectares, 35 km east of Marathon in central-northern Ontario, Canada. Gold was discovered in the area in 1947 and during 1945-1959 a strip of ore with a capacity of 80,750 tonnes and a gold grade of 8 g / t was delineated in the feldspar and feldspar-quartz porphyry then thought to be cut. Between 1960 and 1980, deposits produced across Trans Canada Road (Route 17) were periodically surveyed and mined by wooden piles for prospecting and disposal. In January 1981, Corona Resources Exploration Limited began a detailed survey of the exploration area
