초록

밀양납석광상의 지표시료와 시추시료의 광물조성과 화학조성 분석결과를 통하여 열수변질양상과 형성 환경을 연구하였다. 밀양납석광상의 열수변질대는 광물조합을 근거로 주로 엽납석-딕카이트(석영) 광물조합을 가지며 납석광체에 해당하는 강이질변질대와 견운모-석영-딕카이트를 주로 수반하는 필릭변질대 및 녹니석-석영이 주된 광물조합으로 수반되는 프로필라이트변질대 등 세 가지로 구분된다. 지표 및 시추시료의 수평적 수직적 변질양상 및 지화학적 특성을 통하여 연구지역 내 납석광체는 수차례의 열수변질작용을 통하여 형성되었으며, 현재 채광이 이루어지고 있는 지표광체로부터 남쪽-남동쪽 심부에 이르기까지 대규모로 연장되어 있을 것으로 여겨진다. 납석광체의 광물조합 및 엽납석의 다구조형(2M) 등을 통하여 밀양납석광상의 형성온도는 약 $300-350^{\circ}C$ 내외일 것으로 추측된다.

Hydrothermal alteration patterns and environment are studied by mineral assemblages and chemical analyses of surface and core samples from Miryang pyrophyllite deposit. The alteration zones of this deposit can be divided into three zones on the basis of mineral assemblage; advanced argillic, phyllic, and propylitic zone. Advanced argillic zone mainly consists of pyrophyllite-dickite (-quartz) and corresponds to principal mining ore. The common mineral assemblage of phyllic zone and propylitic zone are sericite-quartz-dickite and chlorite-quartz, respectively. Horizontal and vertical alteration patterns and major element geochemistry indicate that pyrophyllite ores have been formed several times by hydrothermal alteration. And it also suggests that the huge ore bodies may be extended from the deeper part of recent quarries to the south-southeastern direction. The paragenesis of ore minerals and polytype (2M) suggest that ore deposit was formed at about $300-350^{\circ}C$.
