摘要
通过对已知矿床不同级序的地质、地球化学和地球物理等客观属性的分析，研究了冀北地区铅锌银矿床成矿的地质要素．认为成矿地质属性在时空结构上具有一定匹配和耦合规律，前寒武纪和中新生代地质作用在空间上的耦合，与不同尺度的接触带构造在时间上的匹配，构成了四维时空格架：从矿床～矿带～成矿区，成矿地质要素分别是接触带构造。
The northem Hebei Province, one of the importan metallogenic provinas in China and located in the north edge of North china platform,is host to an important bulk of Pb-Zn-Ag mineralization.This paper presents an analysis of objective attributes in geology,geochemistry,and geophysics that occur in different sequences of the known mineral deposits,and of the metallogenic geological attributes in the Pb-Zn-Ag deposits in the northem Hebei Province. The research shows that certain pattems of matching and coupling between metallogenic geological attributes exist in the time-space structure.The spatial coupling in geological process between the Precambrian and the MesoCenozoic,and the temporal matching in structure between contact zones in different sizes constitute and ordered fourdimension spatial and temporal framework.In terms of mineral deposits→mineral belts→metallogenic zones,the metallogenic geological attributes can be defined as the contact structure,the Mesozoic structural-magmatic activity zones and the Precambrian crystallized basement,respectively.
