一种新的造山类型—江苏南部茅山叠覆造山

褶皱造山，推覆造山，火山造山，断块造山等造山类型已屡人们所认识。江苏南部茅山等地存在一种新的造山类型滑覆叠置造山，简称叠覆造山，其概念是：构成原始山体的岩片沿其底部拆离面滑移，并脱离母体叠覆于异地低洼处形成新的山体，多个岩片可依次滑覆呈反序叠置。以茅山叠覆造山为例，论述了叠覆造山的特征，构造要素，形成机制及叠覆构造与推覆构造之区别

New Type of Sliding-Nappe Superimposed Orogenic Motion in the Eastern China

The genesis of mountains and mountain ranges in the earth's surface are mainly resulted from fold,volcano,fault-block and over--thrust,whlch can not explain the formation of Maoskan mountain range in Jiangsu Province,Eastern China. The genetic course of Maoshan Mountain range,the rootless allochthonous microlithons composed of D3 -- S, PI -- CI, T -- PZ strata, were slided and napped reversely,superimposed on the homeland system along a weak decollement bed. The napping properties are displayed in the front section of sliding--nappe structure. New orogenic type especially located in the southern Jiangsu is nominated southern Jiangsu type. Taking the Maoshan Mountain range as an example,the structure type formed by a reversesuperimposed orogenic motion is called Maoshan type,developed usually in the two sides of large mountain ranges. Therefore, a new orogenic and structure have closedly affinity with the large ranges. The dynamic sources of sliding--uappe superimposed orogenic motion come from gravity of blocks or microlithons,gravityextended power and anomalous pore pressure.
