Relationship of grade, tonnage, and basement lithology in volcanic-hosted epithermal precious-and base-metal quartz-adularia-type districts Relationship of grade, tonnage, and basement lithology in volcanic-hosted epithermal precious-and base-metal quartz-adularia-type districts
Examination of grades, tonnages, and basement rocks for 88 epithermal precious- and base-metal quartz-adularia-type districts in North, Central, and South America, and Japan reveals that the type of basement rock below the mineralized veins is useful for predicting grade and size of deposits. Epithermal districts overlying basement with salt and evaporites, or rocks with trapped sea...

Equivalent radiolarian ages from ophiolitic terranes of Cyprus and Oman Equivalent radiolarian ages from ophiolitic terranes of Cyprus and Oman
Radiolarian biostratigraphy shows that umberiferous strata overlying the Troodos ophiolite in Cyprus are Turonian in age and are thus essentially contemporaneous with similar strata that overlie the Samail ophiolite in Oman. However, this radiolarian age is markedly older than Campanian isotopic ages measured on the underlying rocks of the Troodos ophiolite. The revised age for the...

Petroleum industry drilling in industrialized and developing areas Petroleum industry drilling in industrialized and developing areas
International drilling statistics show significant differences in target depths as well as the mix between onshore and offshore wells. Unlike the USA, where most of the drilling has been concentrated in depths to 5000 f (shallow depths), the preponderance of wildcat wells drilled in South America and Africa reach much deeper horizons. Offshore wildcat drilling represents less than 4% of...

Fluorine in Colorado oil shale Fluorine in Colorado oil shale
Oil shale from the lower part of the Eocene Green River Formation in the Piceance Creek Basin, Colorado, averages 0.13 weight percent fluorine, which is about twice that found in common shales, but is the same as the average amount found in some oil shales from other parts of the world. Some fluorine may reside in fluorapatite; however, limited data suggest that cryolite may be...
