详细的野外地质及矿物学，地球化学.同位素的系统研究表明，晓天&磨子潭火山岩盆地脉状金矿床具有浅成低温热液矿床特征。

Detailed investigations on field geology , mineralogy , geochemistry and isotope geology have shown that the vien type gold deposits in the Xiaotian Mozitan volcanic basin have the characteristics of epithermal deposit and belong to quartz adularia subtype .

已有的河相层序模式仍以基准面为支撑理论，层序界面常按岩相向盆迁移、复合砂体、古流向偏转和无沉积作用面等识别，内部仍为三分。

In recent fluvial sequence models , which take the base level as the supporting theory , the boundaries of sequences are usually recognized from the facies drift towards basin , amalgamated sandy body , palaeocurrent deflection and non depositional surface , and the sequence is divided into three parts .

台地区为浅水碳酸盐岩沉积，盆地区为严重欠补偿条件下的硅质岩沉积。

Platform area was dominated by the sedimentation of the shallow carbonate sediments , and in the basin area the sediment of deep silicalite was developed in under & compensated conditions .
