大渡河从金川发源,汇聚了众多支脉一路向南奔流,当横穿了盆地西南边缘最后一道门坎——瓦山,形成了最大谷深2600多米的壮观秀丽的金口河大峡谷。峡谷内,河床被夹束在两岸由厚达成百上千米、近于水平线的震旦纪灰岩、白云岩等地层断面构成的峭崖陡壁之间,大渡河水在狭隘的谷地中急流翻滚、奔涌而下。漫步峡谷,辨识那层层叠叠、厚达数千米的完美地质剖面,犹如记录了十多亿年来地质演化历史的天书;聆听深不见底、窄如刀缝的绝壁深涧里的水拍石崖,则在无言传递自然的沧桑物语。
The Dadu River originates from Jinchuan, bringing together numerous branches and streams all the way to the south. When crossing the last threshold on the southwestern margin of the basin - Wushan, the Dadu River has formed the spectacular scenic golden rim of the Grand Canyon at more than 2,600 meters. Within the gorges, the riverbed is trapped between steep cliffs formed by layers of stratigraphic sections such as Sinian limestone and dolomite, which are thickly formed up to hundreds of kilometers across the Taiwan Strait. Dadu River tumbles over the rapids in the narrow valleys, Rushing down. Stroll through the canyons and identify the perfect geological profiles that are stacked on top of each other for thousands of kilometers, like the bibles that record the geological evolution of more than 1 billion years. Listen to the underwater shots Stone cliffs, in the silent transmission of the vicissitudes of life.
