Abstract

In this study, Advanced Spaceborne Thermal Emission and Reflectance radiometer (ASTER) image was analyzed to extract spectral characteristics of the Oyu Tolgoi porphyry Cu-Au deposit region in Mongolia. We propose extraction model of alteration zone by making index images using correlation between absorption features of altered minerals and existing band math model. The central Oyu Tolgoi deposit is associated with advanced argillic alteration showing strong absorption feature in the ASTER band 5 and 6. And the south and southwest deposits that are associated with phyllic alteration showing strong absorption feature in the ASTER band 6. In addition, we confirm the evidence of propylitic alteration in some areas around the Oyo Tolgoi deposits by using new band math model to detect propylitic alteration.

ASTER 자료를 이용하여 몽골 오유 톨고이 반암형 구리-금 광상지역의 분광학적 특성을 분석하였다. 오유 톨고이 광상의 분광학적 특성 분석을 위해 변질광물들의 흡수특성과 기존에 제안된 밴드연산 모델 간에 상관관계를 이용하여 지수영상을 생성하고 변질작용에 따른 추출모델을 제안하였다. 분석결과 중앙 오유 톨고이 광상은 ASTER 5번, 6번 밴드에서 강한 흡수특성이 나타났으며, 강이질(advanced argillic) 변질작용과 밀접한 관련이 있는 것으로 판단된다. 반면에 남부, 서남부 오유 톨고이 광상의 경우 필릭(phyllic) 변질작용과 관련이 있는 것으로 판단되며 ASTER 6번 밴드에서 강한 흡수특성이 나타났다. 또한 프로필라이트(propylitic) 변질작용을 받은 지역의 분광학적 특성 추출을 위해 새로운 밴드연산 모델 PROI(PROpylitic Index)를 적용한 결과 프로필라이트 변질작용과 비슷한 특성을 보이는 일부지역을 확인할 수 있었다.
