元谋位于滇西北,紧邻云南与四川交界部位。元谋从大地构造单元看,位于康滇台背斜中部。前震旦纪时,本区为一地槽,有极厚的昆阳统沉积,在沉积过程中地壳不稳定,有小规模的基性岩浆活动,之后地壳逐渐隆起,发生强烈的褶皱和广泛的区域变质作用,并伴随有南北向大断裂的发生。 Yuanmou is located in northwestern Yunnan, close to the junction of Yunnan and Sichuan. Yuanmou from the tectonic unit to see, is located in the central part of Kang Dian Taiwan anticline. During the Pre-Sinian period, the area was a trench with extremely thick Kunyang sediments. During the sedimentary process, the crust was unstable and had a small-scale basic magmatic activity. After that, the crust gradually rose and intense folds and extensive Regional metamorphism, and accompanied by a large north-south fault occurred.
