Abstract
The paper presents the results of study of fluid inclusions from quartz lodes and veinlets crossing the ore body in different parts of the Central district of the Malmyzhskoye gold-copper porphyry deposit (Khabarovsky krai). The authors revealed the staging of deposit formation. Specific chemical and P-T conditions are proposed for different stages. The Raman spectroscopy methods and electron microprobe analysis were used to determine the composition of the multiphase fluid inclusions. These fluid inclusions indicate that the deposit begins to form from the Fe-Ca-Na-К-(Cl-S-С-О-H) melt, which coexists with low density water vapor at a high temperature of about 800-900°С. The porphyry ores in the deposit were formed under the post-magmatic hydrothermal conditions between depths of 1-2 km over a temperature range of 580 to 330°С.
