Auteur :
YANG DAYUAN,

Description :
Based on field survey, chemical and mineral analyses, archaeological data, radiocarbones dates, and pollen diagram, a hypothesis is presented that the rock planes of terraces and their overlying gravels and fine flood sediments were developed in underwater conditions. The coarse gravel layers between bedrocks and fine flood sediments are the relics from erosion.
