Chracteristics and formation setting of granodiorite in Zhalute County, Inner Mongolia

Based on field investigation and study of petrology, mineralogy, geochemistry and isotopic geochronology for the granodiorite, the authors discussed the formation setting of the granodiorite. The pluton is calci alkalic and peraluminous granite in which light rare earth elements (LREE) are intensively enriched, heavy rare earth elements are relatively poor, the ratio of LREE to heavy rare earth elements (HREE) is 7.12, and the fractionation of REE is good. The pluton formed in late orogenic setting which is relatively steady.
