锆石 U-Pb 法年龄数据汇集了1982年7月至1985年底所获得的数据共56个。所涉及的地区有北京、内蒙、山西、辽宁、陕西、西藏、新疆、青海、江西、广东、山东、江苏、湖北、河北、福建等15个省,市、自治区。U、Pb 含量用同位素稀释法在 MAT-261质谱计上测定。 Rb-Sr 法年龄数据为1983年7月至1985年12月期间所测定。共有全岩及矿物 Rb-Sr 等时线42 条。涉及黑龙江、吉林、辽宁、河北、内蒙古、新疆、浙江、湖南、江西、广西、青海、安徽、海南岛等13个省、自治区。测试对象计有岩浆岩31个、沉积岩6个、变质岩5个。其中岩浆岩测试效果最好,年龄数据一般与地质背景相符。沉积岩的适用性尚需进一步研究。Rb、Sr 同位素的测定使用 MAT-260质谱计,采用同位素稀释法。 K-Ar 法年龄数据为1983年7月到1984年3月期间所测。计有单矿物年龄50个,全岩年龄83 个,共133个。测试对象为单矿物黑云母、钾长石、角闪石等,全岩主要为火山岩及中酸性侵入岩。样品采自北京、河北、辽宁、新疆、西藏、湖南、江苏、浙江、江西、福建、广西、广东、山西等13个省、市、自治区,样品测试在 MM-1200质谱计上进行,采用同位素稀释法。
Zircon U-Pb data collected 56 data from July 1982 to the end of 1985. Involved in the area of Beijing, Inner Mongolia, Shanxi, Liaoning, Shaanxi, Tibet, Xinjiang, Qinghai, Jiangxi, Guangdong, Shandong, Jiangsu, Hubei, Hebei, Fujian and other 15 provinces, municipalities and autonomous regions. U, Pb content by isotope dilution method MAT-261 mass spectrometry. The Rb-Sr age data were measured from July 1983 to December 1985. A total of 42 rock and mineral Rb-Sr isochores. It involves 13 provinces and autonomous regions including Heilongjiang, Jilin, Liaoning, Hebei, Inner Mongolia, Xinjiang, Zhejiang, Hunan, Jiangxi, Guangxi, Qinghai, Anhui and Hainan Island. There are 31 magmatic rocks, 6 sedimentary rocks and 5 metamorphic rocks. Among them, the magmatic rocks have the best test results and the age data are generally consistent with the geological background. The suitability of sedimentary rocks needs further study. Rb, Sr isotope determination using MAT-260 mass spectrometry, isotope dilution method. The K-Ar age data were measured from July 1983 to March 1984. There are 50 single mineral age, 83 rock age, a total of 133. Test objects for the single mineral biotite, potassium feldspar, hornblend, etc., the whole rock is mainly volcanic and acid intrusion rock. Samples were collected from 13 provinces, municipalities and autonomous regions in Beijing, Hebei, Liaoning, Xinjiang, Tibet, Hunan, Jiangsu, Zhejiang, Jiangxi, Fujian, Guangxi, Guangdong and Shanxi. Samples were tested on the MM-1200 mass spectrometer using isotopes Dilution method.
