浙江衢州大洲火山断陷盆地构造应力场特征及其与铀成矿关系
Tectonic Stress Field's Characteristic and Its Relationship of Uranium Mineralization at Dazhou Volcanic Faulted Basin in Quzhou, Zhejiang Province
摘要
Abstract
Based on the study of the structural deformation, the occurrence measurement of outcropped conjugate shear joints, and previous research results, the paleo-tectonic stress field of the Dazhou volcanic faulting basin and its relationship to uranium mineralization was studied using mathematical statistics. Four stages of tectonic stress undergone are summarized: pre-Late Jurassic tectonic stage, Moshishan stage, Qujiang stage, and Eocene-Oligocene tectonic stage. And controlling of each stage over uranium mineralization is also discussed. Finally, this study suggests that late three tectonic stages have close relation to the uranium mineralization, I. E. The Moshishan tectonic stress field provided space for mineralization, the Qujiang stage provided conduits, and Eocene-Oligocene tectonic stress destroyed or reformed previously-formed orebodies.关键词
