加拿大萨德伯里矿田的构造型式及其演化

加拿大萨德伯里铜镍硫化物矿床为著名的世界最大铜镍矿床,其金属铜、镍的蕴藏量及年工业产量在一个多世纪以来始终居世界首位。该矿田已知有大型矿床10余个、中小型矿床30余个。矿床的形成和分布明显受环状岩浆杂岩及北东、北西向两构造体系的控制。

SUDBURY STRUCTURAL SYSTEM IN CANADA AND ITS DEVELOPMENT

Sudbury copper-nickel mineral deposits are well known in the world, which pertain the biggest Cu & Ni mineral reservation and have been keeping in the first of the Ni production in the world since the end of last century. It supplied almost all nickel resources for USA military industry during the Second World War. There are more than ten big Ni-Cu sulphide mineral deposits in the Sudbury Mineral Field, and about thirty of Middle & small mineral deposits.
