In
    this paper, the authors found volcanic rocks in the west mine of this area,
    which occur mainly in the slate surrounding iron orebodies. They are mainly
    composed of intermediate or acidic volcanic rock series, including dacitic
    breccia tuff, dacitic fused breccia, and dacite. The volcanic rocks are
    characterized by porphyry structure and aphanitic tuff texture. The dacite is
    microcrystalline structure, while feldspar and quartz phenocrysts are of
    well-developed microcracks. The quartz shows a harbor structure with good ablation.
    Secondary sides, volcanic glass and its debris also occur in the feldspar.
