The principal period of volcanic activity produced large volumes of mainly acid and basic volcanic rocks accompanied by volcaniclastic sediments which contain isolated coal seams.火山活動的主震時期產生了大量的主酸性以及基性火山岩，並伴隨着火山碎屑沉積物，且其中包含着分離的煤層。

The formation has the character of a volcaniclastic flyschoid sequence deposited on an active continental margin where the sedimentation was accompanied by only a weak magmatic activity.羣系有着火山碎屑類復理石層序特徵，此層序沉積於活動大陸邊緣，在那裏沉積酌只會遇到弱岩漿活動。

The volcaniclastic rocks can be seen as fused lumps, fused breccias and fused tuffs.火山碎屑岩可見熔集塊巖、熔角礫岩和熔結凝灰岩。 ^[1]
