西藏冈底斯成矿带东段中、新生代斑岩成矿系统岩石地球化学与年代学测试数据集

Lithogeochemical and Chronological Test Dataset ofMesozoic and Cenozoic Porphyry Metallogenic Systemin the Eastern Section of the Gangdise MetallogenicBelt, Tibet

西藏冈底斯成矿带东段中—新生代斑岩成矿系统岩石地球化学测试数据集基于冈底斯成矿带地质矿产调查项目“西藏冈底斯东段中新生代斑岩成矿系统与找矿预测”资助,进行岩石测试分析整理而得。岩石地球化学与地质年代学数据可以全面地反映岩石与矿床成因、成岩与成矿年龄等重要信息,为西藏冈底斯成矿带东段中、新生代斑岩矿床成矿背景与成矿模式研究提供科学依据和基础数据支撑。本数据集为Excel表格型数据,包括3个.xlsx类型文件(majorelement_Gangdise.xlsx,traceelement_Gangdise.xlsx,reos-upb_Gangdise)分别记录主量、微量、测年数据,其中majorelement_Gangdise.xlsx包含141条记录和105个字段,traceelement_Gangdise.xlsx包含273条记录和166个字段,reos-upb_Gangdise包含208条记录和100个字段。其中,主量、微量元素数据涉及与邦铺、达布、程巴、甲玛4个矿床有关的5个岩体。测年数据包括邦铺钼多金属矿床黑云母二长花岗岩等4组锆石U-Pb年龄数据,达布铜(钼)花岗岩体等3组锆石U-Pb年龄数据,甲玛铜多金属矿床5组Re-Os年龄数据,邦铺钼多金属矿床2组Re-Os年龄数据。本库提供全部测试均在国家知名测试数据实验室进行,数据质量可靠。

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.
