摘要
The Lu-Zong volcanic basin is a terrestrial inheriting volcanic basin developed through 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.
