line-height-rule: exactly" class=MsoNormal>In this paper, the U-Pb age of zircon separated from the weathering crust of Jibu Huangsha granitic intrusions was dated by using Laser Ablation-Multicollector Inductively Coupled Plasma-Mass Spectrometry (LA-MC-ICPMS). Combining with the reports of other Indosinian granites in the Nanling district, it was concluded that Indo-China movement had a great effect in the Nanling district and produced larger scale magmatic activity with more outcrop areas than was previously understood. The higher latitude of Huagnsha intrusion further indicated the intrusions described in the geological report of Xingguo, Jinggangshan, and even the Ninghua unit in a scale of 1/200 000 also have the potential to host ion adsorption type REE deposits, which should be significant for ore prospecting. oft-com:office:office" />
