It is divided into three subgroups each consisting of multiple named formations. In stratigraphic order i.e. youngest at the top, these are:
Blair Atholl Subgroup
Islay Limestone Formation
Mullach Dubh Phyllites Formation
Lismore Limestone Formation
Cuil Bay Slates Formation
Ballachulish Subgroup
Appin Phyllite & Limestone Formation
Appin Quartzite Formation
Ballachulish Slate Formation
Ballachulish Limestone Formation
Folded metamorphic rocks of the Lochaber Subgroup in Glen Nevis
Lochaber Subgroup
Leven Schist Formation
Glencoe Quartzite Formation
Binnein Schist Formation
Binnein Quartzite Formation
Eilde Schist Formation
Eilde Quartzite Formation
This whole succession reflects alternate periods of deepening and filling of the sedimentary basin.[1][2]
