Abstract

Ilmenite deposits are developed along the Precambrian intercumulated anorthosite body in Jikjeon-Ri, Bukcheon-Myeon, Hadong, Korea. Both detailed geological survey and drilling prospecting data for seven boreholes can be used to do resource estimation with GOCAD S/W. 3D modeling using geostatistics is applied to predict the shape and size of Ti ore bodies. As a result, 5 Ti ore veins occurred along N-S direction and average grade of Ti and ilmenite resources are calculated as 2.98 wt% Ti and 7,494,303 metric tons ilmenite ore reserves (Ti 223,330 t). This 3D modeling will be applied to the whole ilmenite deposits in Hadong-Sancheong area to predict the exact distribution and resources estimations of Ti ores.

하동군 북천면 직전리 일대에는 선캄브리아기 간극누적형 회장암체 내 티탄철석 광상이 발달하고 있다. 정밀 지질조사를 통한 노두 자료와 7개 공의 시추탐사 자료를 바탕으로 GOCAD S/W를 사용하여 티타늄의 자원량을 평가하였다. 티탄철석 광체의 지하 부존상태 및 규모를 예측하기 위해 3차원 모델링을 수행한 결과 5개 맥상 광체가 남북방향으로 발달하였으며, 지구통계학적 기법을 활용하여 평균품위 및 자원량을 산출한 결과 Ti 평균 품위 2.98 wt%, 티탄철석 광량 7,494,303톤 (Ti 223,330톤)이 산정되었다. 이번 연구에 수행된 3차원 모델링을 하동지역 회장암 내 티탄광상 전체에 적용함으로써 티타늄 광체의 3차원적 형태와 자원량 평가에 활용할 수 있을 것이다.
