- Abstract:
- The basement of Baihetan Hydropower Plant is the E’mei Mountain Basalt.Analyzing the exposed formations of the dam site can conclude that lithologic characters is mainly from the third to the sixth lithological member which belonged to Emeishan Basalt series.It is consisted of basalt lava(including massive basalt,porphyritic basalt,and amygdaloidal basalt),pyroclastic-lava,volcanic breccia and tuff.We can get the markings to correctly divide the rock formations in the volcanic rock areas by investigation of formations of top side structural features,lithology and variations in the lithofacies at each breaks,rock mechanics character analysis and rock slide research.The symbols of top boundary mostly are air hole,most of them are round,the interlayer of pyroclastie-lava between lava and physiognomy character and so on.The symbols of bottom boundary of lava are drawing air hole,tubular and herringbone air hole or green bottom.
