沿乌鲁木齐——伊宁公路婆罗科努山西段,群峯环抱的赛里木湖南岸果子沟,发育寒武——震旦系沉积,由此往东数十公里,在大河沿子以南科古尔琴地区亦有分布(图1)。在果子沟含漂砾的一套震旦系沉积,前人资料称为,“凯拉克提群”,在科古尔琴地区,对于含漂砾的一套沉积,统称“震且系”,未进行明确肯定。本文将冰川沉积从中分别划出,沿用原地方名称,其岧石组合分别称为“科古尔琴组”、和“凯拉克提组”,前者代表震旦纪早期一次亚冰期,称“科古尔琴亚冰期”,后者代表震旦纪晚期一次亚冰期,称“凯拉克提亚冰期”。
Along Urumqi-Yining Highway, the western part of Borneo Mountain, Qunfenggou embarks on the south bank of the Sericuigou, the development of Cambrian-Sinian sedimentation, which east tens of kilometers east along the river along the South Division Gulch area also has distribution (Figure 1). In the fruit ditch with a boulder of a set of Sinian deposition, the predecessor information called, “Kaylaketiqun”, in the Korqinqin area, for a set of deposits containing boulders, collectively referred to as “earthquake and system” No definite affirmation. In this paper, we divide the glacial sediments respectively, and use the original local names. The stone assemblages are called “Kogul group” and “Kelaketi Formation.” The former represents the first glacial period of the Sinian, Gulchinya glacial “, the latter on behalf of a Sinian Late Arctic, called” Kaylaketiya glacial.
