| Abstract: | 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. |
