The albitites, distributed widely within the low-grade metamorphic strata of Lower Silurian and Devonian in the Xunyang-Baihe basin of the South Qinling orogen, are usually regarded as the product of hydrothermal sedimentation or hydrothermal metasomatism. The study conducted the geochemical and zircon U-Pb LA-ICP-MS dating analysis for the albitite intruding into the low-grade metamorphic rocks of the Lower Silurian Meiziya Formation in the Huanshiban area in the eastern part of the Xunyang basin. The geochemical analysis shows that the albitites are characterized by Na-rich, K-depleted, aluminum unsaturated, LILES-depleted such as K and Rb, and HFSE-riched such as Nb, Ta, Th, Hf, with negative Eu anomaly. The youngest U-Pb age of zircon from albitites is 364~376 Ma, and it should represent the formation age of the albitite, suggesting the Xunyang Basin in the South Qinling Orogen was in an intense extensional tectonic setting during Late Devonian. Results suggest that both the hydrothermal-related and magmtogenic albitites probably coexist in the Xunyang-Baihe basin. The Huangshiban magmtogenic abitites contain abundant xenocrysts zircons of Precambrian and Early Paleozoic, and the oldest zircon age (3291 Ma) has been obtained for the zircon xenocrysts in the South Qinling orogen and its adjacent areas. The dating data of zircon xenocrysts show that the South Qinling Orogen probably has marked affinity with Yangtze block from the Early Archean.
