| 摘 要： | 黑龙江省密山县金沙农场北部鹿山地区被钻孔揭示的城子河组剖面产有海相一半成水相双壳类、沟鞭藻，孢子花粉及植物化石，这些新材料进一步证明城子河组的时代应属早白垩世早中期，从而为侏罗～白垩系界线划分及鸡西群与龙爪沟群对比提供了新的生物地层依据。

| Abstract: | The Chengzihe Formation coal-bearing measures were developed in the Lushan area of Mishan, Heilongjiang Province. The materials dealt with in this paper are mainly obtained from the bores in this area (No. 86-23 and 4-19). The name of this formation comes from the coal series in the Jixi basin. The fossils from the Chengzihe Formation of the area containing dinoflagellates bivalves and spore-pollen have been recently studied by the authors. The geological age of this formation is to early-middle Early Cretaceous. |
