EVOLUTION CHARACTERISTICS OF FENGSHUNCHANG-TIANJING MOUNTAIN STRUCTURES IN NORTH LONGMEN MOUNTAIN
摘要
Abstract
By the studies of the commingled interpretation and the structural evolution of the seismic profiles, Fengshunchang-Tianjing Mountain Tectonics has experience, the following three evolution process from Sinian to Now: extended to generate a basin, gravity gliding and compressional orogenesis under the background of the continental uplift and expansion. At the extensional basin stage (Z-T2) , there were no Fengshunchang-Tianjing Mountain structures, but sedimentated a series of sea facies carbonate and clastic formations. At the gravity gliding stage {T3-J2) , located in the front of the gravity gliding belt of the structural system, Fengshunchang-Tianjing Mountain regionally developed into a series of thrust nappe structures taking thin surface structure as the main form; since Late Jurassic period (J3-Q) , the compressional orogenesis has formed, the background of the structural dynamics changes gradually from stretching/gravity gliding to horizontal compression, accompanied with the basement-involved deformation, and then a series of advance thrust structures taking thick surface structure as main form are produced. After eroding, the above structures manifests as nowaday structural patterns.关键词
