河台金矿成矿地质特征与深部找矿

Mineralization characters of Hetai Gold Mine and exploration of deep mineral deposits

河台金矿是一典型的大型韧性剪切带含金蚀变糜棱岩型矿床.古老变质岩地层、韧性剪切带特征和成矿动力及物质来源等方面都十分有利于成矿,但垂深600m以下未有工程控制,资源不清,很难直接用工程找矿.文章从已经开展的成矿地质研究和地球化学探索研究资料的分析入手,建议在物化探的系统研究和建立成矿模型的基础上,对深部进行成矿预测和工程验证,尽快控制一定的资源量.

Hetai Gold Mine is a typical altered mylonite gold deposit. The mineralization at this mine is favored by its old-aged metamorphic rocks, tough shear-band characters, and high driving force and rich substance supply for mineralization. It is however difficult to explore the mineral deposits under 600M directly by means of the conventional exploring engineering, because of a lack of engineering control of the deposits, and of unknown deposit distribution there. It is therefore suggested that a further work on the prediction and engineering confirmation of the deep mineralization be done by constructing a mineralization model, making use of the geological and geochemical data of deep mineralization, and employing the already obtained physical and chemical exploration results, so as to get control of the deposit resources in a short future.
