准噶尔石炭纪—三叠纪经历了4次重要的气候事件,即晚石炭世降温事件、中二叠世温室事件、晚二叠世—早三叠世干旱事件和中—晚三叠世潮湿事件.古气候的发展往往有周期性,每个大的周期又常常是许多小的波动(小周期)发展积聚的结果,这种周期性变化与地球在太阳系中的位置、大气圈、海洋、极地冰川系统的变化、火山喷发以及块体位移有着紧密的联系. The Junggar Carboniferous-Triassic experienced four major climate events, namely, the Late Carboniferous cooling event, the Middle Permian greenhouse event, the Late Permian-Early Triassic arid event, and the mid-late Triassic humid event The development of palaeoclimate tends to be periodic, and each large period is often the result of the accumulation of many small fluctuations (small cycles) that are related to the Earth’s position in the solar system, the atmosphere, the oceans, the polar Glacier system changes, volcanic eruptions and block displacement are closely linked.
