| 1. | These cyclic sequences are overlain by the lagoon dolomitic mudstones and shales 米级旋回层序之顶覆以厚度不等的 |
| 2. | Lys is the most abundant residue when only " single " cyclic sequences are taken into account 若仅考虑“单一”环状序列时,组成中赖胺酸出现之频率最高。 |
| 3. | These cyclic sequences may be divided into three types : " deepening " - upward asymmetrical type , " shallowing " - upward asymmetrical type and symmetrical type 运用旋回等时对比法则对短期基准面旋回层序进行等时对比,并建立等时地层格架。 |
| 4. | These biostromes and bioherms , together with tidal - flat dolomicrite and muddy dolostone , form circum - tidal flat meter - scale carbonate cyclic sequences with symmetrical facies sequences and fabrics 它们与潮坪相泥晶白云岩和泥质白云岩构成具对称相序组构的环潮坪型碳酸盐米级旋回层序。 |
| 5. | Viewed from the ordered stacking patterns of the meter - scale cyclic sequences in the long - period sequences , twenty - six third - order sequences may be identified in the wumishan formation 因此,七级韵律层、米级旋回层和五级准层序组分别与岁差旋回、短偏心率旋回、长偏心率旋回间存在有成因联系。 |
| 6. | Therefore , the seventh - order rhythmites , meter - scale cyclic sequences and fifth - order parasequence sets are correlative in origin with precession of equinox cycles , short eccentricity cycles and long eccentricity cycles , respectively 常常3 - 5个米级旋回层序呈有序叠加构成五级准层序组,少数米级旋回层序还可识别出5个七级韵律层而呈现出1 5的叠加关系。 |
