Whether ancient cities,toponym,products,literature or achievement ofarchaeology and recording of stratigraphy,useful information that we canget from each of them is restrictivist,only colligating them can reflectall-sided courses of environmental changes in this region,also can makecertain the cause of environmental changes in science and make researchingtheories have more reliability.
不管是古城、地名、物产、文学描述,还是考古成果、地层学记录,各代用指标都有自身的局限性,把它们综合起来,将各不同指标提取的环境意义相互补充和比对,则能够比较全面地反映区域的环境变化过程,也能够比较科学地判定环境变化原因,使研究成果更具可信度。

The study shows that the advantageous sandstones in the area have the following distribution characteristics: in the environment of growth faults, sandstones are mainly distributed in the downthrown block of a boundary fault; in a lowstand systems tract, sandstones are mainly distributed in lowstand wedges, slope fans, basin-floor fans, fan deltas, deltas and submarine canyons; in a transgressive systems tract, sandstones are mainly distributed in sandbars and sand-beaches; and in a highstand systems tract, sandstones are mainly distributed in deltas, fan deltas and submarine fans.
并指出有利砂体的分布特征:低水位体系域,砂体主要分布在低水位楔、斜坡扇和盆底扇;高水位体系域,主要分布在三角洲、扇三角洲、海底扇和峡谷水道。研究表明,以层序地层学理论为指导,划分层序和体系域,进而对有利砂体进行预测,对该地区油气勘探有重要指导意义。

Three short geomagnetic excursions, the Go thenburg, Mono Lake and Mungo in the Brunhes Positive Polarity period, were revealed based on the studies of magnetostratigraphy, susceptibility and δ^18O of sediments in core WP 92-5 from the central temperature area of the Western Pacific Warm Pool, and the ages of them are 12.1--11.3 kaBP, 25.0--24.0 kaBP, and 31.0--28.0 kaBP respectively. Furthermore, the Younger Dryas and Heinrich cold events were also discovered in this core by the susceptibility record.
