| 摘 要： | 通过湖光岩玛珥湖沉积物高分辨率的Fe/Mn比值、Rb/Sr比值、Sr元素强度和550℃烧失量的研究,重建了湖光岩地区全新世以来的古环境演化历史,即：早全新世是气候适宜期,气候温暖湿润,中、晚全新世开始气候逐渐干旱化。这种气候演化模式体现了全新世季风演化的全球性。湖光岩玛珥湖沉积物反映的全新世以来的冷暖变化事件与北大西洋...

| Abstract: | Future environment evolution is a great composition of global change research.High resolution paleoenvironment study can help us to understand the rules of past global change and provides scientific basis for forecasting future environment evolution.As a special type of crater lake,maar lake has unique advantages in forming and conserving high resolution geological record.Elementary assemblages of the lake sediment are not only affected by depositional environment,but also linked to geochemical property of ... |
