Title: Characteristics of Heavy Minerals and Provenance Analysis of Chang4+5 of Yanchang Formation in Tiebiancheng Region
Abstract: Zircon,tourmalin,garnet and leucoxene are often predominate in Chang4+5 of Yanchang formation,Tiebiancheng region.Based on surface texture of heavy minerals and variety trend of their stability in the plane,they can be divided into three types of combinations from east-north way to south-west: garnet+ zircon+ tourmalin,zircon+ garnet+ tourmalin,zircon+tourmalin.Variety trend,combination characteristics of heavy minerals and constituent characteristics of clastic rocks,indicate that the east-north way is main provenance region of Tiebiancheng.Quartz cathode luminescence characteristics indicate that the source mother rock of Tiebiancheng belongs to a middle-low class metamorphic rock,and simultaneously show that Luliang Mountain and Daqing Mountain in the east-northern Ordos basin are main material sources of Tiebiancheng region.
