摘要
云南省金矿区域成矿特征主要表现在 :(1)构造 -热动力条件控矿的明显性 ;(2)成矿时间的长期性和成矿期的滞后性 ;(3)金矿床类型的多样性 ;(4)金矿床空间分布的集中性。作者分析上述区域成矿特征之后 ,对云南省金的构造成矿区 (带 )进行了初步划分。划分了2个构造成矿域 ;5个构造成矿区 (带 ) ;12个金成矿区 (带 )。
Regional gold-forming characteristics in Yunnan Province are mainly shown in:(1) the markedness of control by tectono-thermodynamic conditions;(2)the long term of gold-forming time and the hysteresis of gold-forming age;(3) the multiplicity of gold deposit types;and(4) the concentration of gold deposits in space.According to the above regional gold-forming characteristics,a preliminary division of gold-forming tectonic zones in Yunnan Province has been presented in this paper,which are composed of 2 gold-forming tectonic domains,5 gold-forming tectonic regions and 12 gold-forming tectonic zones.
