沉积凝灰岩 [chén jī níng huī yán]
sedimentary tuff
- 北衙地区热水角砾岩和热水岩溶可分为4种类型和层次，即①地表相爆发－沉积作用形成的沉积凝灰－角砾岩、热水沉积鲕状灰岩与钙华胶结角砾岩；②与近地表洞穴沉积和垮塌作用有关的热水沉积砾岩和汽爆射流角砾岩；③与热水通道相蚀裂和爆破角砾化作用有关的网络状灰岩角砾岩筒和热水隐爆角砾岩筒；④深部相热水浸煮－蚀变灰岩。
The hydrothermal breccia and karst in the Beiya area are divided into 4 types and zones, including: ① sedimentary tuff and breccia induced by hydrothermal explosion and sedimentation on land surface; ② hydrothermal sedimentary conglomerate and gas-explosive ejecting breccia related to sedimentation in and collapsing of some shallow karst caves; ③ netted hydotherma1 limcstone breccia and hydrothermal explosive breccia pipe related to hydrofracturing, corrosion and explosion in the hydrothermal channels; and ④ yellow granular limestone formed by simmering and alteration in the deep heated water reservoir. - 这套岩性包括了碎屑熔岩、凝灰岩、沉凝灰岩、凝灰质碎屑岩和正常碎屑岩，显示了它们形成于火山－沉积盆地的过渡环境。
This succession of rocks contain clastic lava, tuff, tuffite, tuff clastic rock and normal clastic rock, which suggest they were formed in a transitional environment of volcanic slope to fluvial plain or lake.
