丹巴地区自中生代以来经历了多期的变形、变质和岩浆作用。根据变质程度差异可划分出6个变质带：矽线石带．蓝晶石带，十字石带，石榴子石带，黑云母带和绢云母一绿泥石带。蓝晶石带十字石片岩和石榴子石带斜长角门岩与变玄武岩的矿物Rb一Sr等时线年龄分别为149．0±7．1Ma，160．0±13．0Ma和150．2±2．4Ma，它们代表该区最主要的一次区域动热变质事件年龄。本文还结合已有的年代学资料，讨论了丹巴地区变质作用演化史。
The Danba area has undergone multiple stages of deformation, metamorphism and magmatism since the Mesozoic. According to the degree of deterioration can be divided into six metamorphic belt: sillimanite. Kyanite belt, cross belt, garnet belt, black mica and sericite-chlorite belt. The Rb-Sr isochron ages of kryptonite and gabbro zone parabolic gneiss and basalts are 149.0 ± 7.1Ma, 160.0 ± 13.0Ma and 150.2 ± 2.4Ma, they represent the region’s most important regional thermal metamorphic events age. In this paper, we also discuss the evolution history of metamorphism in Danba area by combining the existing chronological data.
