摘要/Abstract

摘要： 利用新的资料对青藏高原中部风火山地区下第三系风火山群的变形进行了地壳南北向缩短率估算,其值为>41%。缩短时期主要为渐新世末,其次为中新世末。

Abstract: Based on newly acquired deformational data of Fenghuoshan group, we have estimated the N-S crustal shortening of Fenghuoshan area in central Qinghai-Xizang plateau .The shortening is greater than 41%, the majority of which occurred in late Oligocene and the minority in late Miocene.

Key words: Qinghai-Xizang plateau, Fenghuoshan area, Crustal shortening, Tertiary
