| 摘 要： | 吉林省蛟河橄榄石宝石矿床是我国少数几个重要的有色宝石矿床之一。该矿床主要受新生代NE向敦密断裂带以及次级NW向超壳断裂控制，是第三纪船底山期火山喷发的产物。矿石主要为橄榄岩包体。地幔深处的富粗晶橄榄岩，超壳深断裂带，岩浆的快速上升构成了成矿的基本条件。

| Abstract: | The gem peridot mineral deposit in Jiaohe, Jilin is one of important color gem deposits of China. The deposit is developed in the belts of north-eastern strike Dunmi fault zone and secondary NNW-trending ultracrustal fault. The peridot is result of volcanic eruption in Tertiary Chuandishan age. The ores exist mainly as peridotite inclusion. Crystallized coarse grain peridotite in deeper mantle, ultracrustal deep faults and rapidly ascending magma constitute the basic conditions of ore forming. |

| Keywords: | Peridot gem mineral deposit geologic feature ore-forming conditions. |
