摘要
In this paper, the authors conducted a thoroughly investigation on a tectonic-hydrothermal siliceous breccia rock which occurs along the NE trending Yangjishan gold mine-Dingjiashan gold mine-Wangfushan belt. The study indicates that these siliceous breccia rocks are not sedimentary siliceous rocks in Carboniferous strata as previously thought,but belong to a fault-grinding breccia rock.The rock-forming mechanism of the breccia rocks and their relation to mineralization are also discussed in detail in the paper. It is also suggested in this paper that the layer slip fault gravelbreccia zones in other sedimentary strata such as the Devonian /Silurian and Silurian /Ordovician at depths are potential mineralization targets that need to pay more attention in future exploration.
