Longquan Mountains

The Longquan Mountains (Chinese: 龙泉山脉; pinyin: Lóngquán shānmài) are a low-lying range of mountains in Sichuan, China. The mountains are 200 km (120 mi) long, on average 10 km (6.2 mi) wide, and form a ridge-like barrier between the Chengdu Plain and the rest of the Sichuan Basin.^{[citation needed]} They range from Deyang in the north to Leshan in the south.^[1] The highest point of the range is Ximei Mountain (西眉山) at 1,045 m (3,428 ft) in Zhongjiang County.^[2] The Longquan are bisected by the Tuo River in the north that forms a 400 m (1,300 ft)-deep gorge through the mountains.

The Longquan Mountains are the westernmost detachment fold in the Sichuan Basin.^[3] The other detachment folds the region are found in the east of the basin, so the Longquan stand out relative to the alluvial Chengdu Plain in the west and the Sichuan Basin's rolling hills to the east. The Longquan Mountains have shown tectonic activity in the past, although pressure built up at the edge of the Sichuan Basin now tends to release along the Longmenshan Fault, further west.^{[citation needed]}
