| Abstract: | By means of comprehensive study, the alkalic-meta-alkalic basic massif generally called "pyroxene porphyrite" at Langao county in the South of Shannxi may be divided into two petrographical facies from petrological view:cryptovolcanic lava and cryptoexplosion volcanic-elastic facies and be composed of three rocks: olivine-pyroxene porphyrite, pyroxene porphyrite (in narrow sense) and trachytic basalt. |
