| 摘 要： | 根据成矿带预测地球化学理论，对黑龙江省漠河－萝北地区进行了区域金成矿规律的地球化学分析，得出了金成矿带的四条预测准则：１）老基底出露区或隐伏区，２）区域北东向深大断裂带，３）金、砷和锑组合地球化学高背景带，４）燕山期小侵入体集中分布区。根据这四条预测准则，预测出五个金成矿有利区带：１）漠河一富克山区带，２）塔河一塔源区带，３）宽河一黑河一多宝山区带，４）乌伊岭一伊春区带，５）嘉荫－罗北区带。

| Abstract: | In the light of geochemical prognosis of mineralization belts and the geochemical analysis of regional ore-formingmechanism of gold deposits from Mehe to Luobei, four guidiances for prognosis of the gold mineralization belt are summarised asfollows: 1) districts with old crystalline basements exposed or concealed; 2) geochemical fields with high An-As-Sb backgroundvalues; 3) the regional northeastern deep fracturing zone; 4) the districts with concentration of Yanshanian granites. In accordance with these criteria, five favourable gold belts have identified: 1 ) the Mehe-Fukeshan belt; 2 ) the Tahe-Tayuan belt ;3) the Kuanhe-Heihe-Duobaoshan belt ; 4) the Wuyiling-Yichun belt ; 5 ) the Jiayin-Luobei belt. |
