| 摘 要： | 通过在吉南浑江地区开展的白山市等三幅１∶５万区调工作，尝试性地运用层序地层学的理论，初步总结了不同特征的不整合面（层序界面）及凝缩段的识别标志；分析了地层序列中矿产分布特征；探讨了层序分析中以剖面岩石（岩性、组构）、相转换界面的基础研究方法。进而将浑江地区新元古代—早古生代地层划分为三个Ⅱ级沉积序列（超层序）、七个Ⅲ级沉积序列（层序）。 |
| 关 键 词： | 浑江地区 层序地层学 不整合面 凝缩段 |

| Abstract: | The distribution of Jilin Cenozoic volcanos(Paleocene Holocene)shows that from west to east,the characteristics of gradual increase in quantity and area;more varied shapes and arrangment modes;gradual increase in eruptive scale and intensity;gradual complex in eruptive types and becoming younger in age,exhibiting a continuity and an inheritance of the comagmatic evolution as well as showing a development of the alkali-olivine basalt tholeiite trachyte pantellerite. |
