Cenozoic tectonics and seismicity of the northwestern part of the Issyk-Kul' basin (Tien Shan)

The paper presents new pre-neotectonic and neotectonic data obtained by con ventional methods of geology and geomorphology as well as fission track ana lysis used for dating tectonic uplifts for the first time in Kyrghyzstan. I t has been concluded that the setting of extension that acted upon the regi on during most of the Paleogene gave way to submeridional compression in th e Cenozoic. Analysis of main morphologic and structural parameters of neote ctonic features permitted estimation of the extent and rate of crustal shor tening in the west of the Issyk-Kul' basin.
