Abstract:
The Anzishan super-unit consists of four units,and magmatic emplacement deformational struc-tures are developed to different degrees in these units.The main structure is foliation,and dioritic inclu-sions and K-feldspar phenocrysts generally display preferred orientation.The three have a consistent attitude and are distributed parallelly to the contact zone.From the early-formed units to late-formed unit,with weakening deformation intensity of magmatic emplacement foliation structure,the number of dioritic inclu-sions is reduced,the degree of flattening deformation decreases and the oriented K-feldspar phenocrysts are distributed at random.According to the above-mentioned features,the magmatic emplacement deforma-tional structures of this super-unit is classified into strong emplacement deformation,moderate emplacement deformation,weak emplacement deformation and essentially no emplacement deformation zones.
