多阶段地质过程控制下磷-铀共生机制研究进展
Advances in Understanding Phosphorus-Uranium Co-enrichment Mechanisms Controlled by Multistage Geological Processes
摘要
Abstract
Clarifying the genetic mechanism of phosphorus-uranium(P-U)co-mineraliza-tion is essential for deepening the understanding of geological processes,guiding the compre-hensive utilization of resources and environmental protection.This review focuses on clarif-ying the regularities of P-U co-mineralization within China.By systematically reviewing previous literature,it integrates analyses of P-U symbiotic mechanisms,deposit types,spatial-temporal distribution characteristics,material sources,and key ore-controlling factors.P-U mineralization can be categorized into four types:sedimentary type,hydro-thermally altered type,supergene enrichment type,and polygenetic overprinting type.P-U deposits in China are dominated by the sedimentary type and are mainly concentrated along the western margin of the Yangtze Platform and within the South China Fold Belt.Phos-phorus mineralization was dominantly controlled by specific ocean redox window periods dur-ing the geological past,while uranium enrichment was coupled with multi-stage tectonic-hydrothermal activities.The spatial distribution was constrained by paleogeographic patterns and structural domain differentiation:phosphorus enrichment zones were located in paleo-marine basin sedimentary areas,whereas uranium mineralization was confined to tectonically activated belts.The ore-forming materials were derived from both deep mantle sources and continental crustal weathering.The key ore-controlling factors identified were hydrother-mal fluid activity,structural conduits,and redox interfaces.Phosphorus-associated urani-um represents an important unconventional uranium resource with significant potential.Fu-ture research should emphasize its metallogenic mechanisms and resource assessment,provi-ding a scientific basis for the integrated exploration and evaluation of strategic mineral re-sources.关键词
