哈马迪金矿是天津华北地质勘查局近年在苏丹北部发现的中大型绿岩带型金矿。由于特殊的大地构造环境和控矿条件,哈马迪金矿南矿段表现出特异性的金矿化特征。本文通过对南矿段区域构造环境及矿区地质特征的论述,研究了该区金矿化的成因及矿化特征,总结了南矿段在无法准确勘查的情况下的采矿、综合利用方法,评述了该类金矿的经济意义。 相似文献

Gold Headquarter of the CAPF has discovered the Yangshan super large-scale gold deposit in Gansu Province, which is a great breakthrough of gold exploration and prospecting in Western Qinling Mountains of China. The gold resources of this deposit achieved 308 tons with increasing potentials. Preliminary geological investigations indicate that the Yangshan gold deposit is located in the intra-continental collision orogenic belt; and the deposit was formed during the continent-continent collision orogenic processes. The geological characteristics of the deposit are similar to that of the typical Carlin-type gold deposits, while differences still exist. The ore-forming background is notably different from the Carlin gold deposit province in the United States; and the ore-forming fluids are similar with that of the orogenic-type gold deposit. Accordingly, the Yangshan gold deposit is a transitional type between the Carlin-type and the orogenic type gold deposits. At present, the Yangshan gold deposit is the largest Carlin and Carlin-like type gold deposit that is ever discovered in China. Researches on metallogeny, metallogenic model and ore-enrichment regularities of the Yangshan gold deposit are crucial to meet the pressing needs of the current geological investigation and ore exploration of the deposit. 相似文献

贞丰水银洞金矿床是通过成矿预测发现的以层控型为主、断裂型为辅的复合型隐伏卡林型金矿床。是滇黔桂“金三角”金矿勘查区层控卡林型金矿的典型代表。在概括水银洞金矿床地质特征的基础上,对矿区内典型金矿点构造蚀变体作了初步的研究与分析,并结合前人研究资料,从成矿物质来源、成矿阶段2个方面对矿床成矿规律进行探讨,初步认为水银洞金矿床的成矿物质来源主要为深部的隐伏岩体;矿床可划分为沉积成岩期和构造-热液期2个成矿期。 相似文献
