摘要
The Jinniu basin located in Southeast Hubei ore cluster,is one of volcanic basins of the Middle-Lower Yangtze Reaches metallogenic belt. The zircon U-Pb dating of rhyolite porphyry yielded an age of (128±1) Ma in central of the Wubaihao area from Jinniu basin,its (176Hf/177Hf)i and εHf(t) values are ranging from 0.28 247 to 0.28 262 and -2.5 to -7.7,respectively.The granite porphyry and rhyolite porphyry from Jingniu basin are derived from mixture enriched mantle and crustal.Both volcanic rocks and sub-volcanic rocks in the Jinniu basin were coeval with those in the Luzong,and Ningwu basins in the Middle-Lower Yangtze River Belt.The hydrothermal gold deposits and porphyry iron deposits have been paid attention in the Jinniu Basin in the future.
