对位于扬子克拉通块体北缘的汉南侵入杂岩进行了年代学工作. 不同岩性的21个样品得出的Sm-Nd等时线年龄为(837 ± 26) Ma(2σ), INd = 0.511 65 ( 0.000 02(2σ), εNd(t) = +1.9, MSWD = 1.02, Rb-Sr同位素分析结果不构成等时线. 斜长花岗岩中黑云母的40Ar/39Ar年龄为(796 ±20) Ma(2σ), 全岩-磷灰石-斜长石-黑云母Rb-Sr年龄为(824.8 ± 3.8) Ma(2σ), Isr = 0.703 93 ( 0.000 14 (2σ), MSWD = 2.44. 锆石U-Pb不一致线上交点年龄约为876 Ma, 下交点年龄约为273 Ma. 杂岩可能是由同一具有εNd > 0特征的岩浆在837～800 Ma左右扬子克拉通块体北缘快速抬升时冷凝分异结晶的产物.
Chronological work was conducted on the Han-Han intrusive complex located on the northern margin of the Yangtze craton block.The ages of the Sm-Nd isochrones of 21 samples from different lithologies were (837 ± 26) Ma (2σ), INd = 0.511 65 (0.000 02 (2σ), εNd (t) = +1.9, MSWD = 1.02), the Rb-Sr isotope analysis does not constitute an isochronal line.The 40Ar / 39Ar age of biotite in the plagioclase granites is (796 ± 20) ), Ma (2σ), Rb-Sr ages of (824.8 ± 3.8) Ma (2σ), Isr = 0.703 93 (0.000 14 (2σ) and MSWD = 2.44 for all rock-apatite-plagioclase- The age of the U-Pb inhomogeneity line is about 876 Ma and the age of the next intersection is about 273 Ma.Macrite may be rapidly uplifted by the same magma with εNd> 0 at about 837-800 Ma in the northern margin of the Yangtze craton block When the product of condensation crystallization.
