赣杭构造带地处扬子板块和华夏板块的结合部位，是中国东南部一条重要的沉积-火山岩带，沿线分布着一系列含铀火山盆地。对这些盆地中的火山岩地层的时代归属一直存在争议，对盆地中火山侵入杂岩的成因类型、物质来源、壳幔相互作用过程以及形成的构造背景等地质问题存在争议或研究程度较低。本项目拟选择赣杭构造带上研究十分薄弱的盛源火山盆地作为研究对象，对盛源火山侵入杂岩开展岩相学、矿物化学、全岩岩石地球化学和同位素地球化学，以及锆石的原位微区U-Pb定年、Hf-O同位素组成的研究工作，通过和区域上其他火山盆地的对比研究，探讨区域上火山盆地中打鼓顶组和鹅湖岭组火山岩地层的时代归属性问题；并根据这些火山岩的地球化学特征，反演其形成时的深部岩浆过程及动力学机制，探讨赣杭构造带晚中生代的构造岩浆活动演化。

The Gan-Hang Belt is superimposed upon a major suture zone separating the Yangtze and Cathaysia blocks, and is one of the important sedimentary-volcanic belts in Southeast China. A series of uraniferous volcanic basins formed in this belt. The timing of volcanic strata from these volcanic basins is in controversy, and the petrogenesis, sources, crustal-mantle interaction and geodynamic setting of the volcanic-intrusive complexes from these volcanic basins are not well understood, or controversial. This project chooses Shengyuan volcanic basin from the Gan-Hang Belt as the subject investigated. We will carry out petrography, mineral chemistry, lithogeochemistry and isotopic geochemiatry on the Shengyuan volcanic rocks, as well as zircon U-Pb dating and Hf-O isotope analysis. By comparing Shengyuan volcanic rocks to other volcanic rocks in other volcanic basins from Gan-Hang Belt, the aim of this project to discuss the timing of the Daguding Formation and Ehuling Formation from the volcanic basins in the region. Beisdes, base on the geochemistry characteristics, we will establish the deep magmatic processes and dynamic mechanism of the volcanic rocks in the Shengyuan volcanic basin, and discuss the evolution of the tectonic-magmatic activity along Gan-Hang Belt in Late Mesozoic.
