Abstract

The South China Block experienced intense tectonic–magmatic evolution during the Indosinian period, which was recorded by Indosinian granite and has attracted numerous researchers. This paper presents data on the geochronology and geochemistry of Darongshan biotite monzogranite. LA–ICP–MS U–Pb zircon analyses yielded a weighted average age of 250.1±1.6 Ma, which represents the magma crystallization age of the Early Triassic. According to petrographic observation, the main diagenetic minerals of Darongshan biotite monzogranite are quartz, K-feldspar, plagioclase, biotite, and small amounts of cordierite, tourmaline, and garnet. Darongshan biotite monzogranite is aluminum-rich and high in silica. It shows weak negative Eu anomalies (δEu=0.13–0.57) and depleted HREEs. Darongshan biotite monzogranite exhibits significant negative anomalies of high field strength elements (HFSE, e.g., Nb, Ta, Ti, and P) and positive anomalies of large-ion lithophile elements (LILE, e.g., Rb, Th, U, and Pb). Geochemical analyses suggested that Darongshan biotite monzogranite has undergone highly differentiated evolution. According to this study, Darongshan biotite monzogranite is an S-type granite, and its source material developed from the remelting of ancient crustal material. The Darongshan biotite monzogranite granite formed in the island arc environment of oceanic subduction and orogenic stage, further confirming the geological records of the remaining oceanic basin in Qinfang.
