We analyzed 29 surface sediment samples in five submarine volcanoes (TA12, TA19, TA22, TA25, and TA26) located in the southern part of the Tonga arc for trace elements and rare earth elements to investigate characteristics of the hydrothermal alteration of surface sediments. Based on analytical resu...

통가열도 지역 해저화산의 퇴적물은 무엇으로 구성되어 있는가? | , 2010). 이 지역 퇴적물은 주로 규산질 연니, 생물기원 탄산염, 풍화된 화산암 기원의 쇄설물, 주변의 해저화산으로부터 공급된 화산재, 그리고 열수의 침전에 의해 생성된 철/망간 수화물 및 황화광물 등으로 구성되어 있으며, 특히 통가열도 지역의 퇴적물은 철과 망간을 포함한 다른 유용 금속이 동태평양 해령이나 대서양 중앙해령보다 상대적으로 높고, 통가열도 지역 내에서도 퇴적물 내 원소의 분포는 시료가 채취된 지역에 따라서 차이를 보인다(Bertine, 1974; Cronan | |
열수에 의한 열수변질작용 또는 모암변질작용은 무엇인가? | 열수에 의한 열수변질작용(hydrothermal alteration) 또는 모암변질작용(wall rock alteration)은 열수용액과 모암이 반응하여 열적, 화학적으로 평행상태에 도달하는 과정으로 정의된다(Guilbert and Park, 1986). 활발한 열수작용은 모암 이외에 주변 퇴적물에도 영향을 끼쳐 열수공급 환경에 따라 산화망간광물, 탄산염광물, 그리고 황화광물이 형성되며 이 과정에서 퇴적물 내 미량 원소와 희토류 원소의 조성이 변화된다(Moorby et al. | |
활발한 열수작용은 무엇에 따라 산화망간광물, 탄산염광물, 그리고 황화광물이 형성되는가? | 열수에 의한 열수변질작용(hydrothermal alteration) 또는 모암변질작용(wall rock alteration)은 열수용액과 모암이 반응하여 열적, 화학적으로 평행상태에 도달하는 과정으로 정의된다(Guilbert and Park, 1986). 활발한 열수작용은 모암 이외에 주변 퇴적물에도 영향을 끼쳐 열수공급 환경에 따라 산화망간광물, 탄산염광물, 그리고 황화광물이 형성되며 이 과정에서 퇴적물 내 미량 원소와 희토류 원소의 조성이 변화된다(Moorby et al., 1984; Smith et al. |
