摘要

FAMILY: ’Times New Roman’; FONT-SIZE: 14pt; mso-font-kerning: 1.0pt; mso-fareast-font-family: 宋体; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; mso-bidi-language: AR-SA" lang=EN-US>Researches of geology, metallogenetic condition and genesis of the Shangguanchang lead-zinc deposit indicated that the orebody (occurrences) is confined by structural breccia zone in the contact between the dolomite-marble xenolith and the quartz diorite of the calc-silicate rocks of the Longshanyan group, and the mineralization is related to carbonate veins that cemented breccias. The hydrothermal liquid of silicate and carbonate formed by tectonic activities extracted metallogenic materials from the primary ore-bearing source beds, which migrated along fractured zones and was enriched to lead-zinc deposit. The genesis of the deposit should be “tectonic geothermal infilling type”. Regionally, the mineralized zone has a length about 15 km intermittently from Sanqiao of Longxian to Madidou of Zhangjiachuan in Gansu Province, showing a good regional polymetallic setting.
