南阿尔卑斯的二叠系分布颇广,主要出露在伦巴弟(Lombardy)、多洛玛埃弟(Dol-omites)、卡尔尼阿尔卑斯(Carnic Alps)、卡拉万克山(Kalawanke mts.)和尤利阿尔卑斯(Julic Alps)等地区(图1)。受石炭纪末海西运动影响,石炭纪前的沉积经褶皱、隆起和不同程度的变质作用,形成结晶基底。其上形成的二叠纪沉积属于稳定的地台型。
The Pernassus in the Southern Alps is widely distributed and mainly occurs in Lombardy, Dol-omites, Carnic Alps, Kalawanke mts. Julic Alps and other regions (Figure 1). Affected by the Hercynian movement at the end of the Carboniferous, the sediments before the Carboniferous formed folds, uplift and metamorphism to varying degrees to form crystalline substrates. Permian sediments formed on it belong to a stable platform type.
