| 英文摘要 | Ning-Wu basin is the important parts of the Middle-Lower Yangtze River Valley metallogenic belt, where there are widespread porphyry-like type( magnetite-apatite type) iron deposits. However, the researches on precise ore-forming and magmatic activity epoch and tectonic setting are very weak. Based on detailed field geological work, we carried out systematic geochronological study of diorite porphyrite plutons related to porphyry-like type iron deposits in the basin. LA-ICP-MS zircon U-Pb dating for seven diorite porphyrite plutons such as Washan, Taocun, Heshangqiao, Dongshan, Baixiangshan, Hemushan and Gushan intrusions, has been carried out. LA-ICP-MS zircon U-Pb elating yield the ages of 130. 2 +/- 2. 0Ma, 130. 7 +/- 1. 8Ma, 131. 1 +/- 1. 5Ma, 131. 1 +/- 3. 1Ma, 130. 0 +/- 1. 4Ma, 131. 1 +/- 1. 9Ma and 129.2 +/- 1. 7Ma for intrusions respectively. The dating result indicates that different diorite porphyrite plutons in Ning-Wu volcanic basin are all formed in the early stage of Early Cretaceous about 130Ma, which can nearly represent the metallogenetic epoch of the porphyry-like type iron deposits. There are three periods (145 similar to 136Ma, 135 similar to 127Ma, 126 similar to 123Ma) of ore-forming and magmatic activity in the Middle-Lower Yangtze River Valley metallogenic belt. The diorite porphyrite plutons in Ning-Wu basin were the products of the second period magmatic activity and obviously later than the high-k calc-alkaline intrusions related to skarn-porphyry Cu-Au deposits in uplift areas in the Middle-Lower Yangtze River Valley metallogenic belt. The diorite porphyrite plutons in Ning-Wu volcanic basin were thought to be formed under regional lithospheric and thinning environment. |
