| 摘 要： | 庐枞火山岩盆地是以中、下侏罗统陆相碎屑岩建造为基底,经燕山运动而发育起来的陆相继承性火山岩盆地,是长江中下游地区重要的矿集区之一。本文就前人在盆地内柳峰山地区,圈定的潜火山岩——"玄武玢岩",根据最新证据,证实其为喷溢相的火山熔岩——"玄武粗安岩"。另外,指出该岩石是优质的高速公路路面用集料。结论对重新认识该区的火山活动、构造和在该区寻找、开发金属和非金属矿产有重要意义。

| Abstract: | The Lu-Zong volcanic basin is a terrestrial inheriting volcanic basin developed through the Yanshanian Movement,with middle and lower Jurassic terrestrial clastic rock formation as basement,one of important ore concentration area in the mid-lower Yangtze River reach.Based on latest evidence,subvolcanic rock,＂basaltic porphyry＂delineated by former geologists in the Liufeng Mt.area in the basin has been proved extrusive volcanic lava,＂basaltic trachyandesite＂,which can be used as quality freeway pavement aggregate.The conclusion is important to re-recognition of volcanism and tectonism as well as to looking for and developing metallic and nonmetallic ore deposits in the area. |
