| 摘 要： | <正> 黑龙江省东部龙爪沟群及其与鸡西群的对比研究已有30年的历史了。80年代出版了大量专著,地层古生物工作者对二个群地层划分和对比的方案逐步趋于一致(具然弘等,1982;顾知微,1982a;1982b,1982c,1983;顾知微等,1984;李尉荣等,1986;黑龙江省东部中生代含煤地层研究队,1986);90年代,沙金庚(1990,1991,1992)基于双壳类等古生物化石的新发现,提出将龙爪沟群和鸡西群时代修正为白垩纪或主要为白垩纪。作

| Abstract: | Palaeomagnetic and structural data suggest that the Longzhuagou Group should be divided into 2 series of sedimentary rocks, Shangyunshan formation and Kaibei formation, Both are predominantly marine. They were possibly formed at low latitude (15.1-23 N) and close relatively to the Nadanhada terrane. In contrast the predominantly coal bearing Peide and Zhushan formations were formed at high latitude (52.1-57.8N) and close relatively to the Jixi Group, which is the cover of Jiamusi terrane. During amalgamation of the terranes, the two kinds of strata were interlayened with each other structurally. |
