Sichuan Xuanhan Baili Canyons Areas Fold Structure Characteristic And Geological Landscape Research

This article in detail elaborated Sichuan reaches the state Xuanhan hundred miles canyons areas the structure characteristic. Hundred miles canyons are situated are located the Sichuan pendi northeast edge the Daba, its geostructure position belongs to north the Yangzi platform the reason Daba arc Fold, for Daba orogenic zone and its foreland basin union department.Xuanhan hundred miles canyons areas structure by fold primarily, moreover grows quite intensely, its structure characteristic mainly has following several points: Canyon area structural types by fold primarily, extremely few faults occurrence. The fold intensity gradually strengthens from SW -> NE. Folded section geometry type by uniform thickness(parallel)primarily, but is similar extremely does not grow, thus the uncoordinated fold extremely grows. Fold combination type for more typical comb fold, by partition board type primarily. Hundred miles canyons landforms landscape formation and the structure distortion relations is extremely close, mainly was by the fold shape, the intensity, the growth spot has controlled the different lothological level distribution and delivers the condition, outside Canada the power(mainly is rivers and ground water geology function)then has formed the different characteristic landform landscape. These landscapes have watch the value and the geological research value. The paper finally puts forward the proposal regarding hundred miles canyons areas geological traveling development use that, emphasizes in the protection foundation, realization resources sustainable development...
