paleoenvironment
解釋
古環境-
The global change study is one of the most spectacular and interesting environment scientific questions in the 1990 s. the message of global change stores in tree rings, ice core, loess, underground water, lake sediment and deep sea sediment, all these proxies record the information of global change. with the advances in stable isotope techniques, the isotopic tracer records the message of climatic variation and becomes a powerful tool that can understand paleoenvironment reconstruction and modern environment changing
全球變化研究是90年代以來最為引人注目和關切的環境科學問題之一。全球環境變化的信息儲存於樹輪湖泊冰芯黃土地下水和海洋沉積物等載體中，隨著穩定同位素技術的發展，同位素示蹤劑指示環境變化的信息，成為了解古環境再造和現代環境信息變化的一個強有力的工具。 -
The alternative changes of paleoenvironment favored the formation and imbedding of brine, which is the source of salt - water intrusion ; and the paleochannel that formed during regressive of sea level is the path of salt - water intrusion
海進時期，大面積的濱海平原被淹沒，在近海平原窪地滯留的海水經過蒸發、濃縮變為鹵水，成為鹹水入侵的物源；海退後陸源碎屑在濱海地區沉積形成了巨厚的古河道砂層。 -
It is important to study salawusu stratum using paleomagnetism method, to give some magnetic proof in age range, stratum correlation, paleoenvironment and paleoclimate, to test former research result. this paper has done systemic paleomagnetism investigation, at dishaogouwan section its magnetic character is : susceptibility value is relatively high and its curve fluctuates little, magnetic mineral is mainly magnetites. the susceptibility ams ellipse is oblate
隨著古地磁學及其分支學科的發展和成熟，以及在一些古人類遺址研究中的成功運用，對薩拉烏蘇地層進行系統的地磁學研究，從磁學的角度提供一些年代歸屬、地層劃分與對比、古環境、古氣候方面的成果，對近年來的研究成果進行印證或檢驗，為研究的焦點問題提供古地磁學依據很有必要。 -
