Abstract

Abstract

Early Paleozoic volcanic rocks developed in Nuomuhong area can be devided into two types. One is the basic volcanic assemble, mainly consisting of tholeiite basalts with low SiO₂ and alkali. Its characteristics of REE, trace elements and tectonic setting reveal that it formed in middle ocean ridge tectonic setting. The other is called middle-basic volcanic assemble with complex rock types and well developed lava and pyroclastics. The volcanic rocks belong to subalkali and alkali series, and the subalkali rocks belong to calalkali series. The charecteristics of REE, trace elements and tectonic setting indicate that they formed in volcanic arc tectonic setting.
