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。 Seven trace fossils have been found within the Lower Carboniferous water group of the area: Skolithos, PalaeophycusSP., Chondrites, Didymaulichnus, Fucusopisis, Lockeia and Planolite’s. The research should be attributed to the combination of Skolithos relics. According to the trace fossils, physical fossils and sedimentary characteristics, the water testing group in this area is mainly formed in the Barrier Sand Bar --- Tidalgum --- Binhai Lagoon System. The main recoverable seams are developed in peat swamps with low-energy tidal flat and shallow lagoons.
