| 摘 要： | 碳酸盐岩溶蚀孔缝中充填矿物包裹体特征对古岩溶作用环境和期次具有较好的指示性。黄骅坳陷奥陶系充填矿物包裹体物理特征反映古岩溶作用环境为埋藏型，包裹体化学特征显示了古岩溶作用与有机质熟化程度有关。包裹体各项特征指标的明显差异性与古岩溶作用的多期性相对应：3种盐度类型反映了浅埋藏、中等埋藏和深埋藏3种环境；4个均一温度段与古岩溶发育的4个期次相吻合。

| Abstract: | The characteristics of mineral inclusions that are filled in the corroded holes and fissures in carbonate rocks can effectively indicate the environments and periods of palaeokarst actions. The physical features of mineral inclusions reflect the burial condition of Ordovician palaeokarst in Huanghua Basin. The chemical characteristics of mineral inclusions show the relationship between palaeokarst actions and maturity of organic matters. The obvious diversities in inclusion indices are consistent with multi-phase characteristics of palaeokarst actions. The three types of concentration reflect respectively three kinds of environments:shallow burial,me- dium -depth burial and deep burial. The four phases of homogenization temperature are accord with the four periods of palaeokarst development. |
