摘要：

阿尔金山并非印支运动后(或更早)即为塔里木、柴达木二盆地的界山。事实证明:两盆地在第四纪以前都是彼此沟通、相互连接的,具相似的成盐、成钾条件。阿尔金山在中新世后方具雏形呈水下隆起;第三纪末(2.60—2.10Ma.B.P.)进一步抬升呈岛状隆起;更新世晚期(0.25Ma.B.P.)方真正成为阻隔塔里木、柴达木二盆地的界山。

Abstract:

Altun Mountains were not boundary mountains between Tarim and Qaidam Basins after Indo-China movement or even earlier.It has been proved that the two basins werelinked up and connected to each other before the Quaternary.They share the same condi-tions of salt and sylvite generation.It was not until Post-Miocene that the mountains hadits embryonic shape of subaqueous uplifts;it further rose as island-like uplifts at the end of Neogene(2.6—2.10Ma.B.P.),and then became the boundary mountains to block the Tarim and the Qaidam Basins in Late Pleistocene(0.25Ma.B.P.).
