| 摘 要： | 笔者通过对铀源、赛汉组上段沉积建造、构造演化等的分析认为，二连盆地中部具备古河道砂岩型铀矿成矿条件；古河道形态与规模、河道内沉积微相、潜水一层间氧化是铀矿床定位的“三要素”，其不同的组合方式构成了不同的古河道砂岩型铀矿成矿模式。据此，指出二连盆地中部具有较好的古河道找矿远景。

| Abstract: | By analyzing the uranium resource, sedimentary formation of upper member of Saihan formation, tectonic evolution, we believed the paleo-valley sandstone-type uranium metallogenic condition is very well in the middle of Erlian basin. Through analyzing the mineralization feature of paleo-valley type uranium deposits, it was found that the morphology and scale of the paleo-valley, microfacies of paleovalley sediment and epigenetic reformation were the three factors to controll the uranium deposits, and different combination of the factors will form different paleo-valley type uranium metallogenic model. Accordingly, we point out that metallogenic prospect for paleo-valley type uranium deposits is fine in the middle of Erlian basin. |
