THE 2ND QUADALUPIAN-SYMPOSIUM AND PROBLEMS OF PERMIAN STRATIGRAPHY

The article presents information on the Second Guadalupian Symposium i n April 1996 and a meeting of the International Subcommission on Permi an Stratigraphy held in its framework. The main subjects for discussio n both at the Symposium and the Subcommission meeting were the Standar d Stratigraphic Scale for the Permian System and, particularly, the pr oblem of introducing the Guadalupian Series into the scale. The discus sions resulted in the recommendation to subdivide the Permian System i nto three series: the Cisuralian Series with Asselian, Sakmarian, Arti nskian, and Kungurian stages, the Guadalupian Series with Roadian, Wor dian, and Capitanian stages, and the Lopingian Series with Wuchiapingi an and Changhsingian stages.
