| 摘 要： | 根据赣南不同时期的各类型花岗岩体的锆石形态群的研究,确定了赣南在前燕山期形成的隘地体、安西－龙州岩体都是造山花岗岩,寨背岩体,陂头岩体,柯树北岩体和安西－龙州岩体均可能是地幔物质混染地壳物质后形成的。

| Abstract: | Using J.P.Pupin's method,this paper studies the population typology of zircon from 5 granitoids of different types.The features of zircon populations from Aigao granitoid are similar to Saint Sylvestre granites (French Central Massif) and Gueret granites (French Central Massif).These granites are thought to be of typically crustal extraction,having formed under low P T conditions.The characteristics of zircon populations from Anxi longzhou granites are different from Aigao granites.These granites are of Crustal+Mantle Origin(Hybrid Granites).In the fig.of distribution of mean points and mean T.E.T.of zircon populations,Zhaibei granites,Pitou granites and Keshubeidong granites mainly fall in the field of sub alkaline series granites.It is suggested that these granites are of mantle or mainly mantle origin. |
