摘　　要：矿产沉积学是一个沉积学与矿床学交叉而形成的新的学科方向。矿产沉积学属于应用基础学科,主要任务是应用沉积学(沉积动力学、流体动力学、物理化学、微生物沉积学等)的基本原理,探讨成矿元素的迁移-聚集机理和成矿颗粒的风化-搬运-沉积过程,从而恢复沉积矿产的古环境(沉积环境、古盐度、古碱度、古氧化还原条件)和形成背景(沉积盆地、古地理、古气候等),最终目的是确定矿床成因、成矿规律,建立成矿模式和找矿模型,进行成矿预测,为沉积矿产的找矿勘探提供科学依据。同时将成矿事件与重大地质事件相结合,揭示重大地质事件与成矿事件的耦合关系。Ore sedimentology is a new interdisciplinary research direction based on the combination of sedimentology and ore deposit geology.Ore sedimentology belongs to applied fundamental research and its main task is to apply the basic principles of applied sedimentology(sedimentation dynamics,fluid dynamics,physics,chemistry,and microbial sedimentology)to explore the transfer and accumulation of ore-forming elements and the weathering-transportation-deposition process of ore-forming particles.After obtaining above-mentioned information,we can reconstruct the palaeoenvironment factors of sedimentary ore deposits(e.g.,sedimentary environment,palaeosalinity,palaeo-alkalinity,palaeo-redox)and their forming background(e.g.,sedimentary basin,palaeogeography,palaeoclimate).This research aims at providing scientific basis for prospecting of sedimentary ore deposits.To achieve this goal,we need to constrain the origin of ore deposits,summarize the ore-forming rules,build the ore depositional and the prospecting model.Our study cases indicate that there were couplings between the sedimentary ore-forming events and important key geological events.
