补充资料：西加湖矿床
| 西加湖矿床 Cigar Lake Deposit 加拿大铀矿。位于萨斯卡彻温省阿萨巴斯卡盆地东缘。1981年发现，后经钻探落实储量为15万吨，平均品位12.3％（部分为4％）。西加湖矿床属不整合脉型。盆地基底为太古界至早元古界的石墨、泥质片麻岩、花岗片麻岩、角闪岩、大理岩及泥质片岩、变质长石砂岩、石墨片岩等。中元古界阿萨巴斯卡组砂岩覆盖于基底地层之上，呈不整合接触。铀矿体位于地表以下410～450米处，呈平缓状，矿体延伸长2150米，宽25～100米，最厚20米，赋存于不整合面之上的阿萨巴斯卡组底部砂岩层中。蚀变强烈，主要蚀变有伊利石化、赤铁矿化和绿泥石化等。矿石矿物主要为沥青铀矿，伴有Co-Ni砷化物、硫化物、赤铁矿等。 |
