| Abstract: | On the basis of the first field data,some geological characteristics of micropillow structure in volcanic rocks are firstly found and reported along the Manxin area.The age of the volcanic rocks along the Manxin Laochang area are discussed.It is considered that the volcanic rocks in the Yiliu group were mainly formed in late Permain,and in the there was weak basic intermediate volcanism in Devonian-middle late Carboniferous and Triassic period Laochang area |
