周台子铁矿位于河北省滦平县张百湾镇,西距县城29km,东距承德市40km。该铁矿是产于前震旦系单塔子群变质岩系中的条带状磁铁矿。本文对该铁矿的矿石及围岩进行了主微量元素、锆石U-Pb定年及Hf同位素的测定,为探讨周台子铁矿的成岩成矿时代及其地质意义提供依据。1矿床地质特征周台子铁矿位于华北克拉通东部陆块的西侧。区域主要出露单塔子群白庙组和凤凰咀组,前寒武纪花
Zhoutaizi iron ore located in Luanping County, Hebei Province, Zhang Baiwan town, west of the county 29km, Chengde City, 40km east. This iron ore is a banded magnetite produced in the former Sinian system in a single tower metamorphic rock series. In this paper, the main trace elements, zircon U-Pb dating and Hf isotope determination of the iron ore and the surrounding rock were measured, which provided the basis for discussing the age and geological significance of the diagenesis and mineralization of the Zhoutaizi iron deposit. 1 Geological Characteristics of Deposit Zhoutaizi Iron Mine is located on the west side of the eastern block of North China Craton. The region mainly exposed Baita Temple Group and the White Phoenix temple group, Precambrian flowers
