川中古隆起构造演化特征及其与早寒武世绵阳-长宁拉张槽的关系
Evolution characteristics of Central Sichuan palaeouplift and its relationship with Early Cambrian Mianyang-Changning intracratonic sag
摘要
Abstract
In the light of the findings of the early Cambrian Mianyang-Changning intracratonic sag, this paper makes a study related to the structure and evolution for further knowing the basic geology in Sichuan Basin.Based on the palaeotectonic reconstruction of the top of the Sinian strata and by comparing the ranges of the intracratonic sag and the paleouplift at various stages,the present paper deciphers the relationship between the Mianyang-Changning intracratonic sag and the Central Sichuan paleouplift.The result shows that Sichuan Basin can be classified into 12 areas based on the evolutionary characteristics of the intracratonic sag and the paleouplift.The paper proposes that the Central Sichuan paleouplift formed with the evolution of the Cambrian intracratonic sag.The east side and west side of the intracratonic sag are independent tectonic regions,and only during Late Triassic period,they jointed a paleouplift.Their present structural features are the Southwest Sichuan uplift and the Central Sichuan uplift,respectively,especially resulting from the differential evolutions after the Himalayan period.Therefore,the Mianyang-Changning intracratonic sag controls the primary oil and gas geological conditions and the Central Sichuan paleouplift controls the formation,adjustment and preservation of the oil and gas reservoirs of the Lower Paleozoic-Sinian strata.关键词
