形成于晚中新世的吉隆盆地,在7.0~1.7MaBP间充填了厚达300余米的河湖相沉积,自1.7MaBP起喜马拉雅山(以下简称喜山)开始强烈的脉动式上升,盆地遭到来自喜山南坡河流的切割而结束了其沉积历史。根据沉积学、磁性地层学、古生物学和氧、碳同位素等的研究资料,恢复了中新世晚期以来的构造和气候事件。指出喜山上升始于7.0MaBP前,但强烈的上升发生在2.0~1.7MaBP间和0.8MaBP以来,最主要的气候事件发生在5.7MaBP和2.5MaBP,冰期间冰期气候旋回始于1.7MaBP,并于0.8MaBP后得到加强。
The Geelong Basin, formed in the late Miocene, was filled with a sedimentary facies of rivers and lakes thick over 300 meters between 7.0 and 1.7 Ma BP. Since the 1.7 Ma BP, the Himalayas (hereinafter referred to as the Himalayas) began a strong and pulsating rise. To the river from the southern slope of the cut and the end of its deposition history. According to sedimentology, magnetic stratigraphy, paleontology and oxygen, carbon isotopes and other research data, the restoration of the structure and climate events since the late Miocene. It is pointed out that the rise of the Himalayas started before 7.0MaBP but the strong rise occurred between 2.0 and 1.7MaBP and 0.8MaBP. The main climatic events occurred at 5.7MaBP and 2.5MaBP. During the ice age, the glacial climate swirling started at 1.7MpaBP After 0.8MaBP strengthened.
