【摘要】 已知矿(集)区深部经过弱矿(无矿)间隔后新出现的矿化富集空间称之为第二矿化富集带。第二矿化富集带是一种相对特殊的矿化垂向分带现象,对它的研究能为开展"矿下找矿"或"矿外找矿"提供一定的理论依据。控制第二矿化富集带形成的因素主要有:控矿构造场的复杂变化、成矿系统温度场的改变、成矿系统流体场的演化、沉积建造中的多层位控矿作用等因素。第二矿化富集带的研究要点是:首先判别研究区地史时期形成第二矿化富集带的可能性;其次对所研究的矿化富集带的保存条件进行分析。更多还原

【Abstract】 The second enrichment belt refers to a new area where the deep concentrating ore has been through week mineralization and formation.The second enrichment belt is a special kind of mineralization vertical zone.The research on it can provide theory for deep prospecting.The main reason of forming the second enrichment belt are: the complex change of ore controlling structure,the change of ore forming system temperature,the change of ore forming system liquid,multiple stratigraphic horizon ore-controlling in sedimentary formation and so on.The research approaches of the second enrichment belt are to distinguish the possiblity of forming the second enrichment belt in the geological history and to make a research on preservation condition about several enrichment belts.更多还原
