However, there are considerable differences in their initial Sr and oxygen isotope compositions, indicating that the monzogranite was not derived from the granodiorite.

然而二者的初始Sr同位素组成存在一定的差异，表明二长花岗岩并非是花岗闪长岩分异作用的产物。

Coincident biotite ~(40)Ar/~(39)Ar ages yield in rocks in the south of Yadong and in the high-pressure granulite shows that on the section of Yadong-ZhergerLa, rocks were cooled to 320℃contemporarily.

亚东以南岩体与哲古拉高压麻粒岩的寄主岩石中的黑云母~(40)Ar/~(39)Ar年龄一致，说明在亚东—哲古拉剖面上，岩体同时冷却至黑云母对Ar同位素体系的封闭温度(~320℃)，推测之后在7~8Ma前近同时冷却至~110℃。

Evidence from isotopic dating suggests that the greenstone belts vary considerably in age.

来自同位素年龄鉴定的证据指出，绿岩带在年龄上彼此变化相当大。

Seven wolframite separates from both topaz-quartz vein type and greisen block type tungsten ores were selected for Sm-Nd analysis.
