The re gional tectonic stress fields and basement tectonics are two fundamental factors to control the cover tectonic framework. This paper uses the finite-element method with a elastic-plastic pIan problem model to simulate the three periods of stress fields resulting from field geological study’ Based on these works, the formation and evolution of tectonic framework of Lu’ an mining area have been discussed.展开更多

This coal, oil and gas basin has undergone a complex tectonic-sedimentary evolution, in which two important stages were the negative inversion from a foredeep to a extensional basin during Early Mesozoic and the positive inversion to a thrust foreland basin in Late MesozoicEarly Cenozoic. The early normal faults residues are recognized with the addition of tectonic-sedimentary analysis to confirm the basin extension during Jurassic time and its tectonic inversion subsequently.展开更多
