Abstract:
The data base for the ore-Cenozoic porphyry metallogenic system in the eastern section of the Gangdise metallogenic belt, Tibet is supported by the Gangdise Metallogenic Belt Geology Mineral Survey Project. Data from petrogeochemistry and geochronology can reflect the genesis of rocks and deposits and the age of diagenesis and mineralization, which will provide a scientific basis and basic knowledge on the metallogenic background and mode of the Mesozoic-Cenozoic porphyry deposit. The data base is conducted in Excel, and includes three.xlsx files recording major, trace and age data:majorelement_Gangdise.xlsx includes 141 records and 105 fields; traceelement_Gangdise.xlsx includes 273 records and 166 fields; U-Pb and Re-Os isotope geochrondogy-Gangdise includes 208 records and 100 fields. The data about major and trace elements involves five rock masses related to Bangpu, Dabu, Chengba, and Jiama deposits. The dating data includes four groups of zircon U-Pb age data of a biotite adamellite in the Bangpu molybdenum polymetallic deposit, three groups of zircon U-Pb age data of a granitic pluton in the Dabu copper-molybdenum deposit, five groups of Re-Os age data in the Jiama copper polymetallic deposit, and two groups of Re-Os age data in the Bangpu molybdenum polymetallic deposit. The data provided by the base were carried out in a well-known national test data laboratory, and thus data quality is reliable.
