通过系统地层学研究，在桂西北地区三叠纪地层中识别出５个层序。金含量在地层中具有周期性变化的规律。低位体系域是金的有利赋存层位。火山作用和海平面变化对含金地层的形成起到了控制作用。
Through systematic stratigraphic study, five sequences were identified in the Triassic strata in northwestern Guangxi. The gold content in the formation has a cyclical change rule. The lower system tract is a favorable layer of gold. Volcanism and sea level changes have played a controlling role in the formation of gold-bearing formations.
