达尔拉德超群包括格兰扁（最古老）、阿平、阿盖尔和南高地（最年轻）群（图13），由岩性多样的变质沉积物和典型的镁铁质变质火山岩组成。该超群可能是完全晚前寒武纪的年龄和基础面积约48000平方公里的北部和西部爱尔兰，苏格兰和设得兰群岛。达尔拉德的底部和顶部都看不到，但是，考虑到每一组保存的最大厚度，并且不考虑构造增厚，计算出它的总累积厚度为c。25.5公里.
The Dalradian Supergroup, comprising the Grampian (oldest), Appin, Argyll and Southern Highland (youngest) groups (Fig. 13) consists of lithologically diverse metasediments and typically mafic metavolcanic rocks. The supergroup is probably entirely late Precambrian in age and underlies an area of about 48000 km 2 in north and west Ireland, Scotland and Shetland. Neither the base nor the top of the Dalradian is seen but, taking the maximum thickness preserved for every group and making no allowance for tectonic thickening, it is calculated to have a total cumulative thickness of c. 25.5 km.
