We occur together with telluride minerals. Fluid inclusions in the euhedral quartz crystals are mainly aqueous liquid-rich inclusions, which have salinities about 0.18-2.24 wt% NaCl equivalent. Some quartz vein contains aqueous vapor-rich inclusions as well. Homogenization temperatures of the assemb...

천열수 광상이란? | 천열수 광상은 고심도(paleo-depth) 약 1km 이내의 상대적으로 천부 환경에서 형성되는 열수광상으로서(Henley, 1991; Lindgren, 1922) 주요한 자원으로는 금-은 혹은 구리-아연-납 등 비금속(base metal)이 있다(Einaudi et al., 2003; Hedenquist, 1987; Simmons and Browne, 2000). | |
함 금-은 열수 내에 텔루륨이 있는 것을 알 수 있는 이슈는? | 열수들은 기존에 형성된 구조대를 따라 이동하며 석영맥을 만들었을 가능성이 높다(Kim, 2011). 열수의 상승과정에서 열수 비등작용을 겪으면서 함 금은 광물을 침전시켰을 것으로 판단된다. 이 과정에서 황철석이 함께 침전되었으나, 대부분의 금-은은 함 Te 광물상과 함께 독립적으로 혹은 황철석 내에 포유물로써 침전되었다. 이는 함 금-은 열수 내에 상당량의 텔루륨이 있음을 지시한다. | |
천열수 광상은 어떻게 구분되는가? | , 2003; Hedenquist, 1987; Simmons and Browne, 2000). 천열수 광상은 크게 지열 시스템의 천수와 광화유체의 혼합으로 인한 중성의 유체와 관련되어있는 저유황형(low-sulfidation)과 화산 vent인근의 산성의 마그마-열수 환경로 인한 고유황형(highsulfidation)으로 구분된다(Barton and Skinner, 1979; Hedenquist, 1987; Henley and Ellis, 1983; Ransome, 1907; White and Hedenquist, 1995). 세계적으로 알려진 천열수 광상은 미국 캘리포니아의 McLaughlin, 미국 네바다의 Round Mountain, Goldfield, 미국 콜로라도의 Summitville, 일본의 Hishikari, Iwato, 피지의 Emperor, 뉴질랜드의 Golden Cross, 칠레의 El Indio, 그리고 필리핀의 Lepanto 등이 있다(Heald et al. |
