Magnetic, gravity, resistivity and refraction seismic surveys were made in a 2.5 km2 coastal area of titaniferous magnetite sand deposits at Meleman village, East Java. Magnetic anomaly data are consistent with models having an average susceptibility of 2.5 x 10 emu/cm? and negligible remanent magnetization with shapes of observed dunal topography or buried lens…
Industrial minerals in Indonesia are widely distributed, although in some cases the deposits are not sufficiently abundant to be exploited in large scales. The Directorate of Mineral Resources is assigned to conduct mineral explorations and inventories, and has a long experience on these jobs. The mineral deposits will be discussed include bentonite, kaolin, natural zeolite, di…
