加拿大安大略省地质矿产资源概况

The general situation of geology and mineral resources,Ontario,Canada

加拿大安大略省的矿产资源丰富,主要有镍、铜、铂族元素、金、铁、银、锌、钼、铀、铅、铬、锂、钛、钨等21种金属矿产,其形成时代主要为中太古代至新元古代,上述矿产按照其形成的地质背景划分为17个三级构造分区和6个主要的成矿区带:①阿比提比金铜镍铁成矿带;②科博尔特镍铜铂族铀成矿带;③尤奇金铜成矿带;④瓦比贡金铜铁成矿带;⑤瓦瓦金铜铁成矿带;⑥格林威尔锌铁铀成矿带等。在安大略省主要的矿床类型有:①岩浆型铜镍矿床;②绿岩带型金矿;③VMS型铜锌矿床;④斑岩型铜钼矿床;⑤喷流沉积(SEDEX)型矿床;⑥金伯利岩金刚石矿床等,其中岩浆型铜镍矿床和绿岩型金矿床为该区重要的优势矿种,值得重点关注。

Ontario, Canada is abundant in mineral resources mainly including nickel, copper, PGE, gold, iron, silver, zinc, molybdenum, uranium, lead, chromium, Lithium, Titanium, Tungsten and other seven kinds of nonferrous metals deposits, most of them formed in the periods from Neo - Proterozoic to meso - Arehaean. According to their geological background and structural charac- teristics, all the above -mentioned mineral resources can be divided into 17 third -class structural units and 6 important metallogenic belts as followings ： （1） Abitibi Au - Cu - Ni - Fe metallogenic belt ; （2） Cobalt Cu - Ni - PGE - Uranium metallogenic belt ; （3） Uehi Au -Cu metallogenic belt; （4） Wabigoon Au -Cu -Fe metallogenic belt; （5） Wawa Au -Cu -Fe metallogenic belt; （6） Grenville Zn- Fe - Uranium metallogenie belt. The deposit types in Ontario Province mainly include magmatic type copper - nickel deposit, greenstone -hosted type gold deposit, VMS type deposit, porphyry type copper and molybdenum deposit, SEDEX type deposit, kimberlite type diamond deposit, of which, the magmatic type copper - nickel deposit and greenstone - hosted type gold deposit are the more signifi- cant deposit types for their superior mineral resources and should be paid attention to explore.
