摘要
成矿系统是指在一定地质时空域中 ,控制矿床形成和保存的全部地质要素和成矿作用过程 ,以及所形成的矿床系列和异常系列构成的整体 ,它是具有成矿功能的一个自然系统。成矿系统理论要点是 :①成矿是一个由发生、持续到终结的开放的复杂动力系统 ;②成矿作用产物包括矿床系列和异常系列 ,它们共同构成矿化网络 ;③成矿系统研究的是矿床形成、变化、保存的全过程 ;④成矿系统的研究 ,必须与成矿背景环境的研究一体化 ,并按构造动力体制进行分类。成矿系统研究的三重意义在于 :①推动成矿学的深入发展 ,并有利于矿床学与地球科学其它分支学科的相互渗透 ;②在找矿预测中建立战略观点和整体思路 ,促进区域找矿和资源潜力评估工作 ;③研究成矿系统中有害组分的污染程度 ,为矿区环境质量评估和环保工作提供科学资料。论文指出以系统观和历史观相结合的研究方法 。
Metallogenic system refers to a natural system with ore forming function and within certain geological time space zone. It includes the geological factors controlling ore formation and preservation, the ore forming processes and their products. The essentials of metallogenic system theory contain four major points: ① Ore formation is a complex dynamic process including its onset, continuation and finish; ② The products of ore forming processes include ore deposit series and anomaly series. They together compose the ore forming network; ③ Metallogenic system studies the whole process of formation, change and preservation of mineral deposits; ④ The metallogenic systems are investigated under certain ore forming geological settings, and classified by tectono dynamic environments. The significance of metallogenic system study lies in: ① to promote the development of metallogeny and benefit the mutual penetration between ore deposit geology and other disciplines of geosciences; ② to build strategic view and integrated thought in ore prediction and prospecting to accelerate regional ore exploration and mineral resource potential assessment; ③ To provide scientific base for evaluation of environmental quality and environmental protection by studying noxious contents in metallogenic systems and their pollution. Combining the systematic and historical points of view, the study on metallogenic system will develop further to serve the mineral resource supply and environmental protection.
