摘要
正反转构造可以划分为断裂型、褶皱型和混合型３大类，其中断裂型包括下正上逆、上下均正和上下均逆３种地层组合形式；当反转期沿断层的逆冲位移小于早期正断层的最大正断位移而大于最小正断位移时表现为下正上逆；当后期逆冲位移小于早期的最小正断位移时表现为上下均正；当后期的逆冲位移大于早期的最大正断位移时表现为上下均逆．褶皱型包括上凸下凹和上下均凸两种形态。当反转期断裂活动和地层褶皱作用均很明显且作用于同一构造时，形成混合型反转构造．
Positive inverted structures include three main types.fault-type,fold-type,and complex-type.The fault-type has three patterns.①the upper bed showing reverse,but the lower showing normal,② all beds showing normal,③all beds showing reverse.When the thrusting displacement along the pre-existing normal fault is among the largest and the smallest normal displacement,the fault-type positive inversion gets the first pattern. When the thrusting displacement is less than the smallest normal displacement,the fault-type gets the second pattern.If the thrusting displacement is larger than the largest normal displacement,the fault-type gets the third pattern.The fold-type inversion has two patterns.the lower beds downwarping and the upper beds upwarping, all beds upwarping.The combining of fault inversion and the depression inversion forms a complex inverted structure.
