Abstract Detrital gold fulfils the criteria of chemical inertia and physical durability required by indicator minerals but it has not found wide application in this role because may be formed different deposit types. This problem is soluble, generic compositional features hydrothermal differ according to mineralization environment. The distribution as a minor component where other commodities a...

Abstract Detrital zircon geochronology can help address stratigraphic- to lithospheric-scale geological questions. The approach is reliant on statistically robust, representative age distributions that fingerprint source areas. However, there a range of biases may influence any detrital signature. Despite being fundamental and controllable bias, handpicking grains has received surprisingly litt...

Massive Zn-Cu-Fe sulfide deposits at the Garon Lake Mine occur in three sulfide lenses in a group of metamorphosed rhyolite crystal tuffs, metasediments and basalts. The major ore minerals are sphalerite, chalcopyrite, pyrrhotite and pyrite. Minor associated silicates are actinolite, tremolite, chlorite, albite and quartz. Rounded detrital pyrite, magnetite and chert grains and diagenetic p...

We contend that a range of phenomena characterizing temperate deposit-feeding communities in low-energy environments is strongly organized by two principal opposing forces: (1) spatially localized inputs of detritus or new recruits, leading to amosaic of initial patches, with subsequent impacts on spatio-temporal variation of species with limited mobility; and (2) the impact of mobile consumers...

Nutrient enrichment of detritus-based streams increases detrital resource quality for consumers and stimulates breakdown rates of particulate organic carbon (C). The relative importance of dissolved inorganic nitrogen (N) vs. phosphorus (P) for detrital quality and their effects on microbial- vs. detritivore-mediated detrital breakdown are poorly understood. We tested effects of experimental N ...

On April 26, 1996, Public Law 104-134 was Chart 1 .-Payment volume, by type of disbursement, fiscal year 1997 enacted, requiring all Federal payments except tax refunds be issued electronically by January 2, 1999, thus beginning a new era in electronic N Federal tax 10.5% funds transfer (EFT). This legislation, the Debt Collection Improvement Act of 1996-part of the Omnibus Consolidated Resciss...

Single-crystal dating of detrital mineral grains confers a remarkable ability to reconstruct cooling histories of orogens and to place limits on the timing, magnitude, and spatial variations of erosion. Numerous grains from a detrital sample are typically dated, and the statistical variability between populations of ages in different samples provides keys to variations in cooling histories and ...

Objectives: North Odisha Iron Ore Craton (NOIOC) is a distinguished place for iron formation with Banded Formation (BIF) as common and abundant litho type. In few localities in Bonai-Keonjhar belt (BK belt) Channel Deposits (CID) specifically detrital type of deposits occur along BIF. Chamakpur-Inganjharan sector BK located on both sides bank the River Baitarani occupied by Detrital (DID) varyi...

Many aquatic ecosystems are sustained by detrital subsidies of leaf litter derived from exogenous sources. Although numerous studies have examined the effects of litter species richness and identity on decomposition processes, it remains unclear how these effects extend to associated invertebrate communities or how these effects vary spatially according to local environmental context. Using fie...
