A lamp unit for use in photography or video taping having a battery seat which can accommodate batteries of differing configurations. The lamp unit comprises a lamp body and a back plate which defines the battery seat. A plurality of electrical terminals are positioned about the back plate such that when a battery is attached thereto the battery terminals, irrespective of their location on the battery, will be in electrical contact with the terminals on the back plate. 
Oxidation of detrital pyrite as a cause for Marcasite Formation in marine lag deposits from the Devonian of the eastern US
Late Devonian black shale successions in the eastern US contain numerous discontinuities that are characterized by lags containing variable amounts of quartz sand mixed with reworked pyritic andExpand
Marcasite in Black Shales—a Mineral Proxy for Oxygenated Bottom Waters and Intermittent Oxidation of Carbonaceous Muds
Abstract Black shales in the geologic record have long been considered to reflect deposition under anoxic or even euxinic conditions. Although bottom-water anoxia favors deposition of black shales,Expand
Gold accumulation in the Archaean Witwatersrand Basin, South Africa — evidence from concentrically laminated pyrite
Abstract Concentrically laminated pyrite is a relatively common, although volumetrically minor, component of auriferous conglomerates in the Archaean (ca. 3.0–2.7 Ga) Witwatersrand Basin of SouthExpand
Microscopy evidence of bacterial microfossils in phosphorite crusts of the Peruvian shelf: Implications for phosphogenesis mechanisms
Abstract Phosphorites are sedimentary formations enriched in Ca-phosphate minerals. The precipitation of these minerals is thought to be partly mediated by the activity of microorganisms. The vastExpand

Abstract The Devonian Chattanooga Shale contains an uppermost black shale interval with dispersed phosphate nodules. This interval extends from Tennessee to correlative strata in Kentucky, Indiana,Expand
Stromatolites in the Late Ordovician Eureka Quartzite: implications for microbial growth and preservation in siliciclastic settings
Well-preserved siliciclastic domal stromatolites, up to 2 m wide and 1AE 5m high, are found in a 10 to 15 m thick interval within the Late Ordovician Eureka Quartzite of Southern Nevada and EasternExpand

The formation of low-temperature sedimentary pyrite and its relationship with biologically-induced processes
This contribution is an updated review on sedimentary pyrite and on its role in well-consolidated research topics, such as the biogeochemical cycles and the studies on sediment-hosted ore depositExpand
Microbial mat structures in profile: The Neoproterozoic Sonia Sandstone, Rajasthan, India
Abstract Ubiquitous microorganisms, especially cyanobacteria preferably grow on the sediment surface thereby producing microbial mats. In the absence of grazers and bioturbators, microbial mat is aExpand
Sulfur sources of sedimentary “buckshot” pyrite in the Auriferous Conglomerates of the Mesoarchean Witwatersrand and Ventersdorp Supergroups, Kaapvaal Craton, South Africa
Large rounded pyrite grains (>1 mm), commonly referred to as “buckshot” pyrite grains, are a characteristic feature of the auriferous conglomerates (reefs) in the Witwatersrand and VentersdorpExpand
