【摘要】 对含金性不同之黄铁矿进行了电子顺磁共振谱(EPR谱)及远红外吸收光谱的研究表明:含金性不同的黄铁矿,它们的谱学特征也各异。黄铁矿的含金量与其EPR谱的峰数及强度有关,与其远红外吸收光谱的光密度值(D)成密切的负相关关系,据此可评价黄铁矿的含金性,以指导金矿床的找寻。更多还原

【Abstract】 Studies on the characteristics of electron paramagnetic resonance(EPR)and far-infrared spectra of pyrites indicate that there are distinct differences among spectra of pyrites varying in gold content. The gold content of pyrite is related to the number and intensity of EPR absorption peaks, and a close negative correlation relationship appears between the light density value of the far- infrared spectra and gold content of pyrite. Such results can be used to evaluate goldbearing properties of pyrite and guide the exploration for gold deposits.更多还原
