Zircon U-Pb dating and geochemical study of the Xianggou granite in the Ma’anqiao gold deposit and its relationship with gold mineralization

Abstract: Single zircon LA-ICP-MS U-Pb dating and lithogeochemical studies have been performed on the Xianggou monzonitic granitic porphyry outcropped in the Ma'anqiao gold deposit. A weighted average U-Pb age of 242.0±0.8 Ma for Xianggou monzonitic porphyry has been obtained. This corresponds with the conclusions of previous studies indicating a syn-orogenic age (242±21 Ma) of the Qinling Orogenic Belt, suggesting that the formation of the Xianggou granite should be associated with the collisional event of the North Ch… Show more

“…Most granites to the other side of CHF Fault, in the ESQL have U–Pb zircon ages between 220 and 205 Ma, except for some small bodies such as the 241 ± 1 Ma Xianggou Granite (Fig. ; Zhu et al ., ). The 220–205 Ma granites form the T 3 ‐ESQL suite, and the ~240 Ma granites form the T 2 ‐ESQL suite.…”

“…Fresh samples of the volcanic rocks, without late-stage veins, were analyzed for major elements, trace elements, and rare earth elements (REEs) at the Institute of Physical Geography and Geochemistry Exploration, Chinese Academy Geoscience, Langfang, China. For details of the analytical procedure, see Zhu et al (2009b). The major elements were determined by Panatica Axios PW4400 X-ray fluorescence spectrometer (XRF), the GAU11aGSD4a standards were used for monitoring in this procedure, and the analytical accuracies were better than 2%.…”
