对潮水盆地侏罗系陆相含煤地层由下而上建立了五个孢粉组合带，在组合三建立了两个亚组合。① Cyathidites-Chasmatosporites-Disaccites组合 (J11)。② Cyathidites-Chasmatosporites-Cycadopites组合 (J31)。③ Cyathidites minor-Cycadopites typicus组合 (J12)；上部： Cycadopites typicus-Cyathidites minor-Osmundacidites亚组合，下部： Cyathidites minor-Cycadopites typicus-Lycopodiumsporites亚组合。④ Cyathidites-Quadraeculina-Classopollis组合 (J32)。⑤高含量 Classopollis组合 (J13)。
Five sporo-pollen assemblages were established from the bottom up in the Jurassic continental coal-bearing strata in the tidal basin, and two sub-assemblages were established in combination three. ① Cyathidites-Chasmatosporites-Disaccites combination (J11). ② Cyathidites-Chasmatosporites-Cycadopites combination (J31). ③ Cyathidites minor-Cycadopites typicus combination (J12); upper: Cycadopites typicus-Cyathidites minor-Osmundacidites subgroup, and lower: Cyathidites minor-Cycadopites typicus-Lycopodium sporites subgroup. ④ Cyathidites-Quadraeculina-Classopollis combination (J32). ⑤ high-content Classopollis combination (J13).
