加拿大沃伊西湾铜镍矿床是20世纪末加拿大发现的最大矿床,而且近年还有新增储量的发现。该矿床储量不仅在世界同类矿床中排在前几名,而且是岩浆通道模式最经典的矿床。岩体控制矿体,该基性侵入体位于加拿大拉布拉多半岛(Labrador)北部中元古代奈恩深层岩套(Nain plutonic suite)中,岩体主要由西帝普斯岩体和东帝普斯岩体组成,它们由一条隐伏的岩浆通道所连接,矿体就位于岩浆通道中,形成典型岩浆通道成矿系统。岩浆通道的膨大部分形成了奥韦尔德矿床。对该矿成矿特征及其成矿模式的总结,对于寻找与岩浆通道成矿有关的矿床具有指导意义。
The Woyisi Bay copper-nickel deposit in Canada was the largest deposit discovered in Canada at the end of the 20th century, and the discovery of new reserves in recent years. The deposit is not only ranked in the top of its kind in the world, but also the most classic deposit of magmatic channel. The rock mass controls the ore body, which is located in the Nain plutonic suite of the northern Labrador, Canada, and is mainly composed of the Cimini Pith and the East Timor Pusi rock mass, which is connected by a hidden magma channel, the ore body is located in the magma channel, forming a typical magmatic channel metallogenic system. The enlarged part of the magma channel forms the Orbeld deposit. The summary of metallogenic characteristics and metallogenic model of the ore is of guiding significance in the search for mineral deposits related to magmatic channeling.
