Abstract: The examination of the occurrence of the major metallogenic elements such as Cu, Zn, Fe and S and accompanying elements such as Au and Ag from the Liwu, Heiniudong, Wajingou, Sunyelin and Zhongzui deposits in the Jianglang orefield, western Sichuan is based on the in-situ analytical techniques including scanning electron microscopy (SEM), backscattered electron images, X-ray linear and planar scanning, enengy dispersive spectrometry (EDS) and microprobe analysis. These analytical results may provide valuable information for ore dressing, rational utilization, resources and financial security, environmental protection, sustainable development, diagenesis and mineralization of mineral resources.
