滦县地区包括滦县、滦南、抚宁、卢龙一带,是冀东前震旦纪铁矿的主要成矿区之一。 在变质岩系原岩建造特征研究的基础上,本文根据火山岩岩石化学、磁铁矿氧同位素等方面的资料,初步探讨了滦县晚太古代盆地的古构造环境以及磁铁石英岩中主要金属矿物磁铁矿的原生沉积物的性质。从矿物相、岩相、含铁建造组构和层状特征等方面推断成铁盆地的地球化学环境。
The Luanxian area includes Luanxian, Luannan, Funing and Lulong, and is one of the major metallogenic areas of the former Sinian iron ore in eastern Hebei. Based on the study of the characteristics of the original rocks in the metamorphic rocks, based on the data of the petrochemistry and the oxygen isotopes of the magnetites, this paper discusses the paleo-tectonic environment of the Late Archean basin in Luan County and the main metallogenic minerals Properties of primary deposits of magnetite. Inferred from the mineral facies, lithofacies, iron-bearing fabric and stratigraphic features, the geochemical environment of the iron basins is inferred.
