The purpose of the Three Gorges project is to construct a large
dam, forming a large-scale water reservoir in the valley. When the
?nal design reservoir water level is reached, the length of the
reservoir will be longer than 660 km, which extends from the dam
site at Sandouping town to Maoer-Xia Gorge in Chongqing City. The
reservoir crosses the low medium mountainous area consisting of the
fold zone from Sinian system to Mesozoic Erathem, which is
distributed in Hubei Province, HunanProvince,
YunnanProvinceandChongqingCity, tothelowmountainousarea formed by
the fold zone ranging from the Triassic to the Jurassic Periods,
which is distributed in the eastern part of Chongqing City.
Generally, the reservoir area can be divided into two parts. The
eastern part is from Sandouping town to Baidicheng in Fengjie
County, with a length of 160 km. In this part, three portions
consisting of limestone formed the narrow Three Gorges. Between the
Three Gorges are two portions consisting of clastic rocks forming
wide valleys. At the dam site are the Pre-Sinian System crystal
rocks. In the Three Gorges parts, thick bulk limestone
anddolomitearemainlydistributed, sandwichingthinlayersof
sandstoneandshale. The mountain height at the gorge areas is about
600 1,200 m, and the width at thoseareasis only200 300m.
Thegeomorphologycharacterizedby high mountains and deep valleys
formed the famous three gorges, namely, Qutang Gorge in the west,
Wu Gorge in the middle, and Xiling Gorge in the east. The Xiling
Gorge is divided into eastern part and western part."
