CLASSIFICATION OF THE SILVER MINERALIZATION SERIES AND THEIR RELATION TO TECTONIC EVOLUTION IN HUNAN PROVINCE

Based on geological and geochamical analyses and according to the main geological pro-cess during the formation of deposits,the silver and silver associated deposits in Hunanprovince may be classified into two mineralization series. They are one related with intrusionof magma and other with sedimentation-diagenesis.Both the two series further includethree subseries. This classification is very helpful to prognosis of silver deposits.In this pa-per,the main geological characteristics and the distribution of the two mineralization seriesare discussed in detail,and then,an aiialysis on relation of the two mineralization series withtectoniC evolution is made.
