• 岩相古地理

  The sedimentary faces and palaeogeography discover that in early basin development sedimentary assemblage is fan-braided-delta-lake which reflects tectonic active;in mature basin development the sedimentary assemblage is river-lake-delta.

  盆地岩相古地理揭示，盆地早期为反映构造活动强烈的冲积扇-辫状河三角洲-湖泊沉积组合；晚期为反映构造稳定的河流-湖泊-小型扇三角洲沉积组合。
