摘要
弧形构造是较特殊的地质构造形迹 ,属扭动或旋扭构造 ,是在特定的递变应力场中产生 ,具有明显的构造变形相带以及有成效的控岩控矿作用 ,往往能提供作为大型 超大型矿床形成宏观机制的同位成矿边界条件。本文以西南三江地区为重点 ,就弧形构造控岩控矿作用的某些问题作进一步讨论 ,并作出相关的成矿预测。
Arcuate structures belong to rather special geological structure type resulted from rotation and shearing movement, which are occurred in the special gradual variation stress field. They have clear deformational zonation, rock and ore controling function and can provide the boundary condition of homothetic metallogenesis as a macroscopic formation mechanism of the large superlarge ore deposit. Some problems about rock and ore controlling function of arcuate structures and metallogenetic prognosis concerned, especially in the 'Three River'area of Southwest China, are discussed in this paper.
