Integrated Geochemical and Isotopic Dataset of Intrusive Rocks from the Shaxi Deposit in the Lower Yangtze River Metallogenic Belt, China: Whole-Rock Major and Trace Elements, Sr–Nd–Pb Isotopes, Zircon Hf–O Isotopes, and Plagioclase Chemistry

The Lower Yangtze River Metallogenic Belt is regarded as one of the most important Cu-Au metallogenic belts in eastern China. Seventeen porphyry intrusion samples, including thirteen porphyritic quartz diorites and four hornblende diorite porphyries, were collected from drill cores at Longtoushan (ZK6502), Qipanshan (ZK1803), Duanlongjing (ZK2508), and Fengtaishan (ZK810), as well as from outcrops (samples 09SX001-1 and 09SX001-4). To better understand the evolution, petrogenesis, and metallogenic controls of the magmatic rocks in the region, we conducted comprehensive analyses, including whole-rock geochemistry, Sr-Nd-Pb isotopes, zircon Hf-O isotopes, and major and trace element compositions of minerals.
