本文研究的铅锌矿床在大地构造上位于华北地台燕山沉降带中部马兰峪背斜的北翼。北翼主要出露太古界和上元古界地层。 矿区内出露长城系高于庄组一至四段(约相当于二十万分之一地质图中区域地层的一至三段)地层(图1),其岩性略述如下。
The lead-zinc deposits studied in this paper are located on the northern wing of the Malanyu anticline in the central part of Yanshan subsidence zone of North China Platform in the tectonic setting. North Wing mainly exposed Archean and Proterozoic strata. Within the mining area, the Great Wall is higher than the first to fourth member of Zhuang Formation (equivalent to the first to third sections of the regional strata in the geological map of one in 200,000) (Figure 1). The lithology of the Great Wall is as follows.
