中文摘要:为了详细刻画和深刻理解区域流体系统，文章在传统的地质填图方法 基础上，针对流体活动性状及其地质记录，提出了一套区域蚀变_流体填图方法程序，并在 铜陵地区进行了示范性研究，取得了良好效果。这套“蚀变_流体填图”的方法明确了流体 填图的填图对象，填图单位划分理论依据——流体同源性理论，制定了流体系统_流体子系 统_流体单元三级填图单元划分方案。在铜陵地区建立了与成矿流体有关的4套流体系统，即 海西期喷流沉积流体系统、燕山期岩浆流体系统、燕山晚期中低温流体系统和燕山晚期繁昌 火山流体系统，并划分出7个流体子系统和18个流体单元。通过“蚀变_流体填图”掌握了铜 陵矿集区成矿流体的空间分布规律，阐述了不同流体系统的成矿特征。
Abstract:In order to describe in detail and understand comprehensively regional fluid sys tems, the authors, in accord with fluid activities and their geological records and on the basis of the traditional geological mapping method, have advanced a s et of procedures for large_scale alteration_fluid mapping. A tentative study in Tongling area has achieved good results: the mapping objects are determined, the theoretical basis (isogenetic evolution of fluid activity) for the division of units in alteration_fluid mapping is established, and the scheme of three_grade mapping unit systems, i.e., fluid system_daughter fluid system_fluid unit, is wo rked out. Four fluid systems related to ore_forming fluids in Tongling ore conce ntration area is established, namely, Hercynian exhalation_sedimentary fluid sys tem, Yanshanian igneous fluid system, Late Yanshanian low_to_moderate temperatur e (epithermal) fluid system and Late Yanshanian volcanic fluid system. In ad dition, seven daughter fluid systems and eighteen fluid units are determined . Through alteration_fluid mapping, the spatial_temporal distribution of ore_for ming fluids in the study area can be understood, the temporal series and framewo rk of the fluid system can be established, and the ore_forming features of diffe rent fluid systems can be explained.
