| 中文摘要 | 臺灣金瓜石金銅礦區是與第四紀安山岩密切相關的熱液活動,所形成的金銅礦床。根據統計從1895 -1987 年間,金瓜石地區共出產約94 公噸的黃金及100,000 公噸的銅。因此區的土壤、岩石、礦體、河川的沉積物、重礦物及黃鐵礦樣品中,普遍皆含有汞的存在,而且其與樣品中金含量密切相關。本文將介紹利用汞地球化學方法,使用於金瓜石主要及外圍地區探勘的結果,說明可透過簡便又迅速的金箔汞測定儀檢測汞含量,並以汞作為此區金銅礦探勘的示蹤元素。 |
| 英文摘要 | The Jinguashih is a group of andesite-related hydrothermal copper-gold deposits of the Quaternary age, producing 94 tons of gold and more than 100,000 tons of copper from 1895 to 1987. Mercury are generally existent in soils, rocks/ores, stream sediments heavy minerals and pyrite samples in the Jinguashih, and mercury found in these samples are highly related to gold content. This paper will introduce geochemical exploration to evaluate whether mercury is a good pathfinder for these types of deposits on both known outcropping and buried orebodies, as well as on newly discovered mineralizations. |
