摘要
The study and comparison of fluid inclusions with different texture,structure and mineralization intensities in the Haojiahe copper deposit in Yunnan Province revealed that their formation is closely related to the evolution of ore-forming fluids in different rock forming and ore forming stages. Ore source bed and some lean ore bodies of this sandstone-type copper deposit formed by the evolution of fluid during the rock-forming period, at the place of highly mineralization degree can even form disseminated or lamellar ores. Reworking mineralization fluid was the further evolution on the base of the rock-forming period fluid, which formed the final ore body controlled by structure and some banded or vein rich ores.
