| | The Sino-Korean heat source ring strueture system was formed gradually by uparching, contraction and shear-tension of the crust (including Archean base-ment and post-Proterozoic folded covers) caused by accumulation,ascent and diffusion of mantle thermal melts with the Shandong Peninsula as the core; it is the main activity center of heat sources (lava springs, thermal flows, thermal fluids, thermal gas and nuclear heat). Take this heat source ring structure system for example, the authors analyse the relat... | | 中朝热源环形构造系是以山东半岛为核心,在地幔热流熔体的聚集、上升、扩散,致使地壳上拱、收缩、扭张等多次变动(包括太古代基底和元古代以后的褶皱盖层)逐渐发展形成的,是中朝台块主要的热源(熔浆、热流、热液、热气、核热)活动中心区。综合分析铀矿与热源环形构造系的关系、分布特点、成矿环与环式构造结、含铀热源体的产态与剥蚀系数、影象地貌特征区、中性构造域,以及“混合—结合—中合”三合式成矿作用区,在时间、空间和成因上铀矿成矿的立体机制,为勘查铀矿建立新的理论观点和开拓新的找矿方向。 | | 文摘来源 | |   |
