PETROLOGICAL FEATURES AND FORMATION MECHANISM OF PYROCLASTIC FLOWS IN THE LOWER TRIASSIC NANLINHU MEMBER, CHAOXIAN, ANHUI

LI Shuang - ying (Department of Resources and environment Science, Hefei University of Technology, Hefei 230009, China)  
The pyroclastic flow deposits developed in the Lower Triassic Nanlinhu member, Chaoxian, Anhui, are compoesd of pyroclastic rocks which can be further divided into dacite breccia, crystal and glass shard dacite tuff breccia glass and crystal dacite tuff, and tuff. The stratigraphie sequence is classified into 2 cycles including A-C and A-E beds of Bouma sequence. Sequence analysis shows that the pyroclastic flow deposits are of transition facies between the proximal and distal facies. The sediments are of clinothem derived from the volcanic debris erupted in shallow sea area south to Chaoxian
