巴颜喀拉山北麓地区古湖岸线分布广泛,湖相沉积与湖成地貌发育。目前,在扎陵湖和鄂陵湖沿岸可清晰地鬟订分出4级湖岸阶地、多级湖相沉积和古高位湖相沉积。古高位湖相沉积出露的最高海拔为4615m,分别高出现代扎陵湖水面328m、鄂陵湖水面346m:在扎陵湖和鄂陵湖谷地分布着多级湖岸堆积阶地或基座阶地、多级湖相沉积和古高位湖相沉积;在小野马岭、大野马岭、扎陵湖北等地的基岩山丘上。也发育有多级湖相沉积和古高位湖相沉积,其古高位湖相沉积高出现代扎陵湖和鄂陵湖湖面50--350m。巴颜喀拉山北麓古高位湖相沉积的形成时代可能为中更新世。
The ancient lake lines are distributed extensively at north foot of Mt Bayankala, also the lake sediments and lacustrine topography. At present, 4 levels of lake terraces, mtdti-level of lake sediments and high level paleo-lacustrine sedimentation can be clearly observed around the shore of Lake Zhaling and Lake Eling. Exposed maximum altitude of lake sediments is 4615 meters, ex- ceeding 328 meters of the modem Lake Zhaling and 346 meters of the Lake Eling. Multi-level lakeshore piled terraces or base terrace, lake sediments and high level paleo-lacustrine sediments distribute in the Lake Zhaling and Lake Ehng valley basin. Mtdti-level pale- o-lacustrine sediments and high level paleo-lacustrine sedimentation whose altitudes are about 50m to 350m above modem Lake Zhaling and Lake Eling distribute locally at bedrock hills of Xiaoyemaling, Dayemalin, Lake Zhaling north and other areas. The forming age of the lacustrine sedimentation from ancient high level lake at the north foot ofMt. Bayankala could be middie Pleistocene epoch.
