Nd-Sr Isotopic Characteristics and Genetic Discussion of Mesozoic Granitoids of Syntexis Series in South China

华南中生代 同 熔系列花岗岩类的Nd-Sr同位素特征及成因讨论

Cenozoic magmatism in the EMTP ( 18 Ma ) was related to syntexis caused by large-scale strike-slip faulting .

新生代岩浆作用（18Ma）与 陆 - 陆 碰导致的大规模走滑断层作用所引起的 同 熔作用有关。

According to tectonic environments and material sources granitoids of syntexis series in South China can be divided into three types : the continental margin type the continental interior type and the fault depression zone type .

根据产出的大地构造环境和物质来源，华南 同 熔系列花岗岩类可划分为三种类型：大陆边缘型，大陆内部型和断裂拗陷带型。

In the Indosinian-Yanshanian activated region cycle as a result of mantle activation the syntexis series granitoids and related volcanic rocks of mantle plus crust mixed source have been formed stretching along the east coast of China .
