粤东北仁差盆地构造演化与铀成矿构造机制探讨
Tectonic evolution and mechanism of uranium mineralization structure in the Rencha Basin, northeastern Guangdong
摘要
Abstract
The ancient stress factors since the Indosinian movement in Rencha basin and its adjacent area have been recovered based on joint screening and statistical analysis.The Rencha region was squeezed by the north-south stress during the Indosinian time,accompanying the formation of a series of east-west folds and crust thickening.A series of sag-type basins began to form and accept deposition in the early Yanshan orogeny,but the north-south extension led to instability induced by gravity and the embryonic formation of a NNE downfaulted volcanic basin in late Yanshan period.In the Eocene,the basin turned to uplifting and eroding stage,forming a modern tectonic pattern,with the east higher than the west.According to the regional stress analysis and geological characteristics,tectonic evolution model of the Rencha Basin was constructed.In the end,a preliminary fault system evolution of the Rencha Basin was carried out and the relationship between the fault system and uranium mineralization was proposed based on the deformation analysis.关键词
