仓房沟群冲积体系中钙质结核的成因

THE ORIGIN OF CALCAREOUS CORES IN THE ALLUVIAL SYSTEM OF THE CANGFANGGOU GROUP

冲积体系中的钙质结核是广泛存在的,其成因与沉积环境、沉积速率、气候和排水体系有关。通过分析钙质结核的类型和成因,可以了解冲积体系的古地理特征。

Calcareous cores are widespread in alluvial systems, and the origin of the cores is related to sedimentary environments, deposition rates, climates and drainage systems. The paleogeographic features of alluvial systems can be recognized by analysing the types and origins of calcareous cores.
