Abstract: | Volcanic edifice is divided into three facies belts which are crater- near crater facies( CNCF), proximal fa-
cies( PF)and distal facies( DF).The dip ranges of the three facies belts in outcrops are listed:CNCF -40～ 70°,PF-25～ 45°,DF-20～35 °.The liner density of fracture of the three facies belts are listed:CNCF -10～ 30 fractures per meter, PF-3～ 25 fractures per meter, DF-2～ 11 fractures per meter.The coherent value relation of the three facies belts is CNCF |
