摘　　要：Listwanite is a suite of silica-carbonate alteration products formed when CO2-bearing hydrothermal fluids meet and react with serpentinized mafic and ultramafic rocks （Robinson et al., 2005）. This alteration product is of great economic significance. Gold, mercury, magnesite and base metal deposits are often associated with listwanite. In China, the petrogenesis of listwanite and related mineralization has received insufficient attention to date. This outcropping paper reports the study along the northeast edge of the of listwanite Baer ophiolite,Listwanite is a suite of silica-carbonate alteration products formed when CO2-bearing hydrothermal fluids meet and react with serpentinized mafic and ultramafic rocks （Robinson et al., 2005）.
