rock debris dam 石碴坝
Composition——the guartz content in lower J1z is higher than the sandstones of T3x6,but its chert and metamorphic rock debris are apparently lower than the later;Texture maturity——J1z siltstone is much worse-sorted than the T3xv6 sandstone,the thin turbidites in J1z are not seen in T3x successions.
成分——J1z下部粉砂岩石英含量高于T3x6砂岩,而燧石和变质岩屑显著低于后者。 结构成熟度——J1z粉砂岩分选程度显著低于T3x6砂岩,J1z中的薄层浊积是T3x中见不到的。
