Abstract：ID TIMS single zircon U-Pb geochronology is applied to determine the age of the big Kuoshibulake porphyritic granite in North Altyn Tagh,NW China,which gives a crystallization age of 443±5 Ma.The age of the granite is of basis for understanding the main tectonic characteristics in this area and also provides a good reference for the division of the strata there.
