The constitutional characteristics of stable isotopes of hypabyssal hydrothermal gold(copper) deposit in Yanbian Prefecture

Sun Chao (The Research Institute of Jilin Geological Prospecting Bureau of Non Ferrous Metals)  
The formation of hypabyssal hydrothermal gold(copper)deposit in Yanbian Prefecture has relation with mesozoic structure and volcanic secondary volcanic magmatic activity.These deposits belong to a part of mineralized zone bordered by Pacific Ocean.The composition of sulfur isotope has the characteristics of the sulfur of deep seated magma source.The composition of oxyhydrogen isotop shows that the mineralizing fluid is the mixture of magmatic water and atmospheric sedimentation,it goes from deep to shallow and its main component goes from magmatic water to atmospheric sedimentation along with the deepening of the deposit.The composition of carbon isotope has the characteristics of carbon of deep seated source.The isotopes of sulfur and oxygen in deposit proceed from deep to shallow,the activities of atmospheric sedimentation proceed from weak to strong and the exchange of sulfur and oxygen isotopes is stronger and stronger along with the deepening of deposit.
