Abstract

Abstract

This paper proposes a new petrogenetic model for the MMEs (mafic microgranular enclaves) based on a study on the Tangjiangqiongguo pluton in the middle part of the North Lhasa Block,Tibet. The MMEs found in the Tangjiangqiongguo host granitic diorites are hornblende diorites usually presenting axiolite and non-compactly cement with the host rock,with an apparent clearance plane with host rocks. The MMEs have higher Na₂O,CaO,MgO and Fe₂O₃^T contents than the host rocks. The MMEs have distinct REE characteristics from host rocks,with higher REE contents (except La and Ce) and weaker fractionation between LREE and HREE. Both the MMEs and host rocks show characteristics of arc rocks with enrichment in LILEs (large ion lithophile elements) Rb,Cs,K,etc.,and Th and U elements,but depletion in HFSEs (high field strength elements) Nb,Ta and Ti elements. Zircon LA-ICP-MS U-Pb dating yields a 113.9±1.0 Ma age and a 110±1.1 Ma age for the MMEs and host rocks,respectively. Although the MMEs are 4 Ma earlier than the host rocks,they have consistent zircon Lu-Hf isotopes. Synthesizing above petrography,geochemistry and isotopic evidence,we suggest the MMEs are derived from the same source rocks with host rocks. The MMEs experienced a weak plagioclase fractional crystallization,but the host rocks experienced a relatively strong hornblende fractional crystallization in respective secondary magma chamber. The differential magma of the host rock wrapped and carried the earlier formed MMEs (in semiplastic) to subsurface. The most probable petrogenetic model for the Tangjiangqiongguo MMEs mingling between magmas of different periods sourced from the same rock.
