متن کاملDetermining of Geotechnical Domain Based on Joint Density and Fault Orientation at Batu Hijau Mine,West Sumbawa-Indonesia (TECHNICAL NOTE)
The research area is located at Batu Hijau Mine – PT Amman Mineral Nusa Tenggara, administratively located at the southwestern of Sumbawa, West Nusa Tenggara Province – Indonesia. The research area is controlled by tectonism in accordance to close with the active tectonic plate at southern part of this island. The presence of the active tectonic regime causes of the rich deposit of ore minerali...
متن کاملWettability of Common Rock-forming Minerals in a Co2-brine System at Reservoir Conditions
Wettability plays a major role in subsurface fluid migration, however little empirical evidence besides qualitative relative permeability data in this context is known about the characteristics of carbon dioxide (CO2). Core analysts use several methods combined for use in the oil industry, including the USBM (U.S. Bureau of Mines) method and Amott test, supported visually by images from an envi...
متن کاملFirst record of Anopheles balabacensis from western Sumbawa Island, Indonesia.
An anopheline mosquito surveillance was conducted in the malaria endemic areas of Utan Rhee and Lunyuk counties, eastern Sumbawa Island, in 2004 and 2005. Eight species of Anopheles were collected, including a new record of An. balabacensis on the island.
متن کاملREE Zoning in Allanite Related to Changing Partition Coefficients During Crystallization: Implications for REE Behaviour in an Epidote-Bearing Tonalite
Allanite is present in most samples of the tonalitic Bell Island Pluton, with an average mode near 0.05 wt.%. Allanite occurs as cores in igneous epidote-clinozoisite and exhibits characteristic and consistent zoning patterns. REE-rich cores (All40–70) grade out towards epidote-clinozoisite with REE below electron microprobe detection limits. La, Ce and Pr contents are highest in the REE-rich c...
