矿物非线性环带构造研究——以西秦岭寨上金矿床为例

Located in the western part of the Min-Li ore belt in the western Qinling mountains, the Zhaishang deposit is a large Carlin-like type disseminated gold deposit. With the method of field geological investigations, compositional zoning patterns and nonlinear theories, we will study the geology, and metallogenetic geodynamical in thedeposit, we want to exact the information from the mineral banding patterns, and make clear the dynamical mechanism of fractal growth and self-organization in the deposit.

寨上金矿床地处西秦岭礼(县)-岷(县)金矿带西段，金的储量已经达到了120t，许多学者对区域上一些矿床的地质特征、矿物学、流体特征、成矿年代学和成矿规律等方面进行过一些基础研究工作，但是单纯运用这些传统方法未能在该区取得进一步突破。本项目拟运用非线性理论研究寨上金矿床中闪锌矿、白钨矿等矿物环带构造特征，厘清其形成的动力学机制，探讨其与寨上金矿床形成的动力学关系，探索寨上金矿床形成的成矿动力学模式。
