辽北清原杂岩锆石年代学与地球化学测试数据集

The Dataset of Zircon Geochronological & Geochemical Testing of Qingyuan Complex in Northern Liaoning Province

辽北清原杂岩锆石年代学与地球化学测试数据库(集)基于亚洲系列地质图件编制及相关重大地质问题研究项目"亚洲晚太古代地层全球性对比"资助,进行岩石测试分析整理而得。锆石年代学数据可以准确地反映原岩的形成时代与形成后所经历的构造岩浆事件,岩石地球化学数据可以反映岩石本身的化学特征,二者相结合可以为研究辽北地区地壳演化历史提供科学依据与基础数据支持。本文采集了辽北地区清原杂岩中高级变质表壳岩与英云闪长质—奥长花岗质—花岗闪长质(TTG)片麻岩单元中的岩石样品,岩石类型包括片麻状花岗闪长岩、云英闪长质片麻岩、奥长花岗质片麻岩、花岗闪长质混合片麻岩、透辉角闪变粒岩、角闪黑云斜长片麻岩、片麻状紫苏花岗岩、石榴紫苏黑云斜长片麻岩、花岗质片麻岩、角闪透辉黑云斜长片麻岩、变质中性火山岩、黑云斜长片麻岩、斜长角闪岩以及矽线石榴片麻岩等。本数据集为Excel表格型数据,包括2个.xls类型文件(Zircon_U–Pb dating data_QY.xls, Geochemistry data_QY.xls)分别记录了样品的锆石U–Pb测年数据与地球化学数据。本数据集样品测试工作均在国家地质实验测试中心完成,数据质量可靠。

The dataset of zircon geochronological testing of the Qingyuan Complex in Northern Liaoning Province gets its information from the rock testing and analysis activities under the financial support of the project’Global Correlation of Asian’s Neoarchean Strata’,which is actually based on the program’Compilation of Asian Serial Geological Maps and Research of Related Major Geological Thematic Issues’.The zircon chronological data can precisely reflect the protolith’s genetic epochs and their subsequently experienced tectonic-magmatic events.The lithogeochemical data can reflect the chemical features of the rocks themselves.The combination of the above two types of data can provide scientific evidences and basic data support for the study of the crustal evolution in the Northern Liaoning Province.This paper has analyzed the rock samples from the mid-to-high grade metamorphic supracrustal rocks and the tonalitic-trondhjemitic-granodioritic gneiss(TTG gneiss)units in the Qingyuan Complex in Northern Liaoning Province;their rock types include:gneissoid granodiorite,tonalitic gneiss,trondhjemitic gneiss,granodioritic migmatitic gneiss,diopside-amphibolitic leptynite,amphibolitic biotite plagioclase gneiss,gneissoid charnockitic granite,garnet charnockite biotite plagioclase gneiss,granitic gneiss,amphibolitic diopside biotite plagioclase gneiss,metamorphic intermediate volcanic rocks,biotite plagioclase gneiss,plagioclase amphibolite,and sillimanite garnet gneiss.This dataset is of Excel format tables,including 2.xls type files(Zircon_U–Pb dating data_QY.xls,Geochemistry data_QY.xls),which have respectively recorded the zircon U–Pb dating data and the geochemical data of the samples.All the testing process is finished by National Geological Experiment&Testing Center of China with the results being highly reliable.
