求翻译：每个矿化层的边界常常不清晰，但是，脉石层的特征明显。 热变质作用使脉石层局部扭曲（塑性变形），而且，脉石层在成岩后局部产生脆性裂隙和断裂。 因此，在填图时，局部可能难以识别这些岩层。是什么意思？

The boundaries of each mineralized layer is often not clear, however, the characteristics of the gangue layer. The thermal metamorphism of the local distortions of the gangue layer (plastic deformation), and the gangue layer diagenesis after local produce brittle fractures and fracture. Therefore, m

Each silver mineralization of the border layer often is not clear, however, the pulse profile layer of rock. The metamorphic rock comes down to local distortions (plastic deformation), and rock, the pulse in a rock generated after partial and broken brittle fractures. Therefore, when in the reclamat

Each mineralization level boundary is not clear frequently, but, the barren rock level characteristic is obvious. The hot deterioration function causes the barren rock level partial distortion (plastic deformation), moreover, the barren rock level partial produces the brittle crevasse and the break

Local thermal metamorphism of the gangue distortions (plastic deformation), and the gangue in local brittle fracture and fracture after diagenesis. Therefore, when the mapping, a local may be difficult to iden
