| 英文摘要 | The Rushan gold deposit in the Jiaodong Peninsula is currently the largest lode gold in China. Gold occurs mainly in pyrite- and polymetallic sulfide-quartz vein/veinlet stock-works. Fluid inclusions in the deposit are divided into three main types, namely CO2-H2O, H2O-CO2 +/- CH4 and aqueous ones. Microthermometric data show that the pre-gold fluids were CO2-dominant (X-CO2 up to 0.53), and the total homogenization temperatures fall in the range of 298 similar to 377 degrees C. These fluids, modified by fluid/wallrock reactions, gradually evolved into fluids with less CO2 (X-CO2=0.01 similar to 0.19) in the main ore-forming stage, and the total homogenization temperatures range from 170 to 324 degrees C. Hydrogen and oxygen stable isotope data suggest that ore-forming fluids were mixture of magmatic and meteoritic origin. Co-occurrence of gold and sulfides implies that gold was most likely transported in the form of gold-sulfide complexes. The wide distribution Of CO2 inclusions means that the pH variation during gold transportation was controlled by CO2 buffering. (C) 2006 Elsevier B.V. All rights reserved. |
