| Abstract: | The Fangniugou area in Yitong,Jilin province belongs to the early Palaeozoic relic islandarc.In this paper,the characteristics of island arc rock series in this area are described by theinvariable primary elements,microelements,REE and isotope,etc,.The existence of this is-land arc rock series indicates an important significance in explaining the tectonic environmentin the northern part of North China landmass. |
