Decomposition of litter mixtures generally cannot be predicted from the component species incubated in isolation. Therefore, such non-additive effects of litter mixing on soil C and N dynamics remain poorly understood in terrestrial ecosystems. In this study, litters of Mongolian pine and three dominant understory species and soil were collected from a Mongolian pine plantation in Northeast Chi...

The newly discovered Federation deposit, with a resource estimate of 2.6 Mt @ 7.7% Pb, 13.5% Zn, 0.8 g/t Au, and 9 Ag, lies 10 km south the Hera deposit within Cobar Basin Lachlan Orogen. Located just north Erimeran Granite contact between Lower Amphitheatre Group underlying shallow marine Mouramba Roset Sandstone, host siltstones sandstones have been brecciated, intensely silicified, chloritiz...

The Casino Cu–Au–Mo deposit is one of the largest and highest-grade porphyries its kind in Canada, residing an unglaciated region west-central Yukon. A batch 22 stream water samples eight groundwater were collected proximal to for purpose identifying most diagnostic trace element isotopic pathfinders associated with hydrothermal mineralization, as well establishing natural hydrogeochemical base...

Replenishment of mineral resources, especially gold and rare metals, is critical for progress in the mining metallurgical industry Eastern Kazakhstan. To substantiate scientific background exploration, we study microinclusions minerals from rare-metal fields, as well trace-element patterns ores their hosts that may mark mineralization. The revealed compositions gold-bearing sulfide a number typ...

Abstract Unravelling the genesis of metamorphosed mineral deposits can be complicated due to difficulties in separating between primary features and that formed during metamorphic overprint. Such uncertainty exists for stratabound dolomite- skarn-hosted Zn-Pb-Ag sulfide 1.89 Ga rocks Bergslagen lithotectonic unit (BLU) Sweden, where a metasomatic vs. regional origin skarns has long been discuss...

Porphyry Mo deposits are the most important type of resource. They result from a high oxygen fugacity parent magma, which acts as an effective indicator for evaluating mineralization. In ore-forming system porphyry deposits, sulfur exists mainly sulfate in highly oxidized magma but sulfide ores. What triggers reduction mineralization that leads to precipitation has not yet been determined. Most...

Abstract The origins of many supergiant ore deposits remain unresolved because the factors responsible for such extreme metal enrichments are not understood. One factor critical importance is timing mineralization. However, information commonly confounded by difficulty dating minerals. world's largest uranium resource at Olympic Dam, South Australia, exceptional high abundance U allows U-Pb Dam...

introduction the mahour exploration area is a polymetallic system containing copper, zinc and silver. the mineralization can be seen in two forms of veins and disseminations. this area is structurally within the lut block, west of deh-salm village. recent exploration work and studies carried out by geologists on this volcanic-plutonic area of lut demonstate its importance indicating new reserve...

Phosphatases are recognised to have important functions in the initiation of skeletal mineralization. Tissue-nonspecific alkaline phosphatase (TNAP) and PHOSPHO1 are indispensable for bone and cartilage mineralization but their functional relationship in the mineralization process remains unclear. In this study, we have used osteoblast and ex-vivo metatarsal cultures to obtain biochemical evide...
