The southern margin of the Kochkor Basin in the Kyrgyz Tien Shan is actively shortening. The South Kochkor Fault, a reverse fault that places Paleozoic granite on Neogene sediments, varies in displacement from 0-2 km while the structural relief across the basin margin is 4 km. North of the fault, a 2 km thick panel of steeply-dipping to overturned sediments exhibits flexural shearing. This steep section is bounded by limbs of gently-dipping beds to the north and south. Northward, Neogene section is thrust over late Quaternary deposits in two younger episodes of faulting: the Akchop Hills Fault and the Aigyrdzal Hills Fault. Through 1:25,000 scale mapping I have demonstrated that of structural relief in the area is shared by fault propagation folding and faulting on a steep, reverse fault that shallows into a detachment.
A complete geologic map of Kochkor, Kyrgyzstan is included with this thesis as a supplemental file.
