摘要
The Lanuoma Pb-Zn-Sb polymetallic deposit is located 10 km north of Jitang in Changdu basin, hosted by carbonate of Triassic Bolila Group (T3b).The ore deposit occurs in an ore district which is considered to be a part of the Sanjiang base-metal ore-forming belt along the Lancang River. The results of bulk analysis of the fluid inclusions show that Na+ and Cl- are most abundant components in liquid phase. CO2 and trace CH4, C2H6 were detected by bulk analysis and laser Raman spectrometry in vapor phase of the fluid inclusions. These data indicate that the ore-forming fluid is NaCl-type, CO2-rich and hydrocarbon-bearing fluid brine.
