摘要
该区下石炭统测水组内已发现 7个遗迹化石属 :Skolithos、PalaeophycusSP .、Chondrites、Didymaulichnus、Fucusop sis、Lockeia、Planolite’s ,经研究应归属于Skolithos遗迹相组合。根据遗迹化石、实体化石及沉积特征 ,该区测水组主要形成于障壁沙坝———潮坪———滨海泻湖体系。主要可采煤层发育于低能潮坪及泻湖淤浅形成的泥炭沼泽。
As for the Ceishui Formation in this area, the authors have found seven genera of trace fossils, they are Skolithos, Palaeophycus SP., Chondrites, Didymaulichnus, Fucusopsis, Lockeia, Planolite's, and they claim that the listed trace fossils belong to the combination of Skolithos Ichnofacies, and also, the Ceishui formation in this area mainly formed in the Barrier Bar- Tidal Flat-Sea Lagoon-system based on the observation of the trace fossils together with the body fossils and the depositional features. The authors further argue that most of the minable seams developed in the low-energy tidal flat and the peat-march caused by lagoon.
