| Indication of Mineral Inclusion Characteristics to Palaeokarst Actions |
| 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. |
