塔里木盆地轮古东地区前石炭纪古岩溶微地貌及岩溶发育模式
Micro-Paleogeomorphology and Karst Development Model of the Pre-Carboniferous in Eastern Lungu Area, Tarim Basin
摘要
Abstract
Guided by modern karst theory, the paleogeomorphology of the pre-Carboniferous Eastern Lungu area in Tarim Basin was restored by using the combination of impression method and residual method. Based on the identification of 2nd-grade geomorphological units including four types as karst upland, karst steep slope, karst gentle slope and karst basin, 3rd-grade geomorphological units are further divided, including eight types as peak cluster depression, QiuFeng valley, karst dome-depression, peak cluster ridge in valleys, peak hill depressions, QiuCong ridge in valleys, karst valley, karst dome-plains. Through the study of vertical paleokarst zoning, the development characteristics and filling mechanism of karst in different paleolandform units were definite. It is concluded that the karst highland is a recharge area in which developed karst crack and cave system; karst steep slope is a recharge and runoff area in which developed high angle corrosion cracks; karst gentle slope is a groundwater runoff area in which developed underground river pipeline system; karst basin is a discharge area in which developed fissure and hole system with highly filling.关键词
