Mesoarchean Crustal Accretion of the Yangtze Block: Evidence from the Granodioritic Gneiss in the Southern Huangling Anticline

doi:10.19657/j.geoscience.1000-8527.2021.051

Abstract

Abstract:

Granodioritic gneiss in the southern Huangling anticline of the Yangtze block is an important component of the Mesoarchean tonalite-trondhjemite-granodiorite (TTG) gneisses of the block. Geochemical results show that the granodioritic gneiss possesses high contents of Al₂O₃, Na₂O, Sr, and low values of Rb and Ta, which is classified as the high-Al TTG rock series. Moreover, geochemical features of the gneiss are consistent with adakite affinity. In combination with the enrichment of the HFSE (Nb, Ta, and Hf) and depletion of LILE (Th, Pb, and U) on the primitive mantle normalized diagrams of the granodioritic gneiss, indicating that the gneiss could be generated from partial melting of the basaltic oceanic crust during subduction process. Based on the documented 2.9-3.0 Ga TTG gneisses and arc-affinity amphibolite in the northern Huangling anticline, it is proposed that the 2.9-3.0 Ga TTG gneisses in the Huangling anticline represent an event of continental crustal growth of the Yangtze block by horizontal crustal accretion of the micro-continent or small-scale plate tectonics during the subduction process.

Key words: Yangtze block, southern Huangling anticline, granodioritic gneiss, high-Al TTG rock series, crustal growth
