位于扬子地块西缘中段的冶勒花岗岩体 ,为钾质过铝质地壳重熔型S型花岗岩。在岩体中获 350± 19Ma的年龄值 ,表明其侵位时代为早石炭世 ,为攀西古裂谷孕育时期的裂前台背斜隆起阶段的产物。这一成果填补了该区早石炭世岩浆活动的空白。
The Yele granite body, located in the middle section of the western margin of the Yangtze block, is a potash-perlite crustal remelting S-type granite. The age value of 350 ± 19Ma in the rock mass indicates that the emplacement age was Early Carboniferous and was the product of the uplift stage of the frontal anticline in the Panxi paleozoic rifting period. This result fills the gap of the Early Carboniferous magmatism in this area.
