根据南美安第斯和南极半岛二者在地质上的相似性,结合冈瓦纳古陆的再造,南极半岛是环太平洋安弟斯中-新生代造山带的一部分。中安弟斯有丰富的矿产,但若据此而对半岛内部的矿产资源进行预测为时过早,因为这二个地区新生代有着不同的大地构造历史。南极半岛有许多已知的金属矿点,但是没有一个是够矿石级品位的,现在甚至相当长的时期内都无法开采利用。不过这些矿点反映了矿化很广泛,通过进一步填图工作有发现可采矿的可能。 南极半岛的一些矿点、热液蚀变岩石以及多处发现的微量金属矿物,根据已发表的过于简略的资料,难以得出恰当的评价。尽管现在还没有经济意义,但引起人们注意的矿点有:(1)乔治王岛广泛散布的热液(?)黄铁矿-石英脉和浸染状黄铁矿;(2)利文斯顿岛上的一条热液Cu-pb脉,浸染状硫化矿物;(3)昂书尔岛地区,阿德莱德岛、布拉班特岛、梅尔契罗诸岛上的Cu、Fe、Mo等硫化矿物和氧化矿物,呈细脉型和浸染状散布,附近有高温热液蚀变分带,反映了可能为斑岩铜矿的矿化特征;(4)布拉班特岛的富磁铁矿熔岩流;(5)阿根廷岛和特拉·菲尔马岛内层状辉长岩体中岩浆型磁铁矿和铜的矿物;(6)南极半岛东南拉西特海岸,高温蚀变剪切带附近合有Cu、Fe、Pb和Mo的细脉浸染型硫化矿物和氧化矿物为低品位的斑岩型矿床。南极半岛的所有这些矿化和热液蚀变岩石实际上都分布在中——新生代的安弟斯侵入岩套中的深成岩体中。大部份较有希望的矿化点是与西部列岛中的第三纪奥长花岗岩深成岩体有关的热液矿床,由于断层使这些岛屿与南极半岛的北部和中部的陆地分隔开来。
Based on the geological similarities between the South American Andes and the Antarctic Peninsula, and the reengineering of the Gondwanaland, the Antarctic Peninsula is part of the Andean Meso-Cenozoic orogenic belt in the Pacific Rim. There is a wealth of minerals in Chung’an, but it is too early to predict the mineral resources within the peninsula because of the different tectonic history of the Cenozoic in these two areas. There are many known metallogenic sites on the Antarctic Peninsula, but none of them are ore-grade enough to be exploited even for quite a long time. However, these ore deposits reflect a wide range of mineralizations and the potential for mining can be found by further mapping work. Some of the Antarctic peninsulas, hydrothermal alteration rocks and many trace metal minerals found on the basis of published, overly brief information make it difficult to draw appropriate estimates. Although not economically significant yet, attention has been drawn to the following mineral spots: (1) hydrothermal (?) Pyrites - quartz veins and disseminated pyrite widely distributed on King George Island; and (2) Livingston Island (3) Cu, Fe, Mo, etc. on the island of Ambrose, Adelaide, Brabant, Melchior islands, etc. Sulfide minerals and oxide minerals are disseminated in fine veins and disseminated with high-temperature hydrothermal alteration zoning nearby, which may reflect the mineralization characteristics of porphyry copper deposits. (4) The rich magnet of Brabant Island (5) magmatic magnetite and copper minerals in bedded gabbro in the Argentine and Trafalgar islands; (6) high temperature thermal shear scissors on the southeastern LACERT coast of the Antarctic Peninsula Fine vein-pulverized sulphide minerals and oxide minerals with Cu, Fe, Pb and Mo near the cutting zone are of low grade porphyry deposits. All these mineralized and hydrothermally altered rocks in the Antarctic Peninsula are actually distributed in the deep-pluton in the Mid-Cenozoic Andes intrusion suite. Most of the more promising mineralization sites are hydrothermal deposits associated with the Tertiary Ordovician granodiorite plutons in the Western Islands, separated by faults that separate these islands from the land in the northern and central Antarctic Peninsula.
