摘要(Abstract):
格陵兰为前寒武纪地盾区,出露的岩石以片麻岩和上壳岩为主,形成于太古代和元古代一系列碰撞造山环境;在地盾西部、东部和北部边缘广泛发育了元古代-中生代的沉积地层和盆地;岩浆活动贯穿于太古代至新生代,形成了岩性多样、规模不一的岩浆岩。格陵兰矿产资源丰富,已发现铁、金、铅锌、稀有稀土、铂族、铜、镍等多种矿产资源。分析表明,格陵兰西南部、中西部和北部分布的条带状含铁建造是寻找BIF型铁矿的有利靶区;西南部太古代绿岩带、南部凯蒂利屯活动带具有寻找绿岩带型金矿和造山带型金矿的潜力;西南部碳酸岩、碱性岩岩体是寻找稀有稀土金属矿床的主要靶区;西北和东北部发育的沉积盆地和地层是寻找SEDEX型和MVT型铅锌矿以及砂页岩型铜矿的有利地区;西南和东南部分布的太古代-元古代基性、超基性岩是寻找铂族元素和镍矿的有利靶区。
