安徽庐(江)枞(阳)火山岩系是我国东部又一个中生代含矿火山岩系.与宁芜火山岩系一样,以赋存丰富的铁、铜等矿产而著称.这两个火山岩系均发育于继承式火山盆地之中,以中基性和碱性火山岩堆积为主.因而,一般的论著均将它们相提并论. 近年来,我们在工作中发现这两个火山岩系除有相似之处外,尚有许多差异,而这些差异正构成了各自的特点.本文拟从岩石化学角度研究庐枞火山岩系的特点,并兼论与宁芜火山岩系的区别.
The alluvial (Yang) volcanic rock series of Lulu (Jiang) in Anhui Province is another Mesozoic volcanic rock series in the Mesozoic in eastern China, which, like the Ninghu volcanic rock series, is characterized by the presence of abundant iron, copper and other minerals, Inherited volcanic basins, mainly to the basic and alkaline volcanic deposits, therefore, the general treatise will be compared to them.In recent years, we found in the work of these two volcanic rocks in addition to similarities, There are many differences, and these differences are forming their own characteristics.This paper intends to study the characteristics of Luzong volcanic rocks from the perspective of rock chemistry, and also with the Ninghu volcanic rock series.
