Based on recent discovery of independent gold deposits and silver ore bodies at the depth of the Donggou calcite vein type copper deposit,in combination with a preliminary genetic mineralogy study and comprehensive analysis,the authors consider that the genesis of the Donggou calcite vein type copper deposit is distinctively different from that of the Hujiayu and the Bizigou copper deposits.

In Permian Period, isolate carbonate platform margin and reef composite place, auriferous calcite vein had been affected Youjiang fault process.

The lower part of member 1 of Shahejie Formation(Tertiary), as represented by well Gangshen 67 in Dagang oilfield, contains an overpressured belt on the top, which is characterized by the development of calcite veins in micritic limestone and calcareous fine sandstone.

At present,ESR method is one of the ways for measuring the age of calcite,but there are no final conclusions regarding the ESR signals and measurement conditions of calcite.

Therefore, the study of calcite formation age may help research of fault activity times.

It is possible to indicate original environment by the chemical composition of calcite veins and character of the carbon and oxygen isotope.
