蒙脱石化合物是在开放海洋环境转向向斜层盆地时由蒙脱石转化而来的。
Based on the observation that the smectitic is originated by conversion of the smectitetransported to the synclinal basins from the open marine environment , the present study focuses onthe origin of the precursor smectite converted to smectitic is .
The research shows that it is high stress region at both schank and axis above neutral layer , low pressure field below the neutral layer . The shorter the distance is to synclinal axis , the larger the stress and the grads .
