| 摘 要： | 湘中是湖南省重要的金、锑矿产地之一。断裂构造及岩浆热事件分析结果表明：该区断裂构造及岩浆热事件对金、锑矿的分布起着重要的控制作用。断裂构造体系分维值大的地区，金、锑矿产出较多，矿床规模也较大。岩体之岩凸或岩凹等热力集中场所，是金矿产出的有利部位；锑矿床皆分布于高古地温区。区域地层岩石中微量元素分析结果显示，前泥盆系浅变质碎屑岩是主要的矿源层。

| Abstract: | The central part of Hunan province is one of the most important ore concentrated areas of gold and antimony deposits in Hunan, China. The analysis of fault structures and thermal event shows that fault structure and magmatic thermal event play important control roles in the distribution of gold and antimony deposits. There are more and larger gold and antimony deposits in the area with bigger fractal dimension. The hot convergent parts of granite are favorable for the formation of gold deposits, and antimony deposits are all distributed in higher paleo geothermal zones. The results of trace element analysis of regional stratigraphy show that slightly metamorphosed pre Devonian clastic rocks are main source strata for gold and antimony deposits. |
