Abstract The Jadar deposit (Serbia) is a unique end member of the volcano-sedimentary Li class, where main ore mineral jadarite (LiNaSiB3O7(OH)), to date only recorded at locality. We provide first account features based on study drill hole material, complemented by petrographic analysis, whole-rock, and isotopic geochemistry. Li-B mineralization hosted sediments interlayered with tuffs that were deposited in fault-bounded lacustrine basin. Mineralization processes initially involved...
Abstract Volcano-sedimentary (VS) deposits represent a relatively poorly studied and still underdeveloped type of Li resource. These consist mixed volcanic-sedimentary successions deposited in closed basins developed felsic magmatic provinces. The ore VS systems includes complex mineralogical assemblages dominated by phyllosilicates, borosilicates, phosphates. In this paper we review the geologic features with goal providing generalized deposit model, as well an updated classification...
The combination of scanning electron microscope–cathodoluminescence (CL), fluid inclusion analysis and high-resolution probe microanalysis Al, Ti, K Fe in vein quartz has yielded results permitting a greater understanding the complex mineralisation Central Oyu Tolgoi Zesen Uul porphyry-style deposits, southern Mongolia. These data demonstrate relationship between precipitation, dissolution ore deposition as mineralising chemistry changed through time. Four major generations are identified...
Non-technical summary. As we consider a transition to low-carbon future, there is need examine the mineral needs for this transformation at scale reminiscent of Green Revolution. The efficiency gains agrarian came ecological and social costs that should provide important lessons about future metal sourcing. We present three options Mineral Revolution: status quo, incremental adaption revolutionary change. argue sustainable Revolution requires paradigm shift considers wellbeing as purpose...

The Cerro Matoso S.A. Ni laterite deposit in northwest Colombia is an important producer of ferronickel; expanded production ferronickel planned to be 55,000 Mt by mid-2004. developed over a peridotitic protolith that exposed the form elongated hill. deposit’s weathering profile variable both vertically and laterally, 10 distinct lithostratigraphic units have been characterized. Two typical sections through were sampled from area mine with high (pit 1) lower 2) grades. Bench mapping has...

Hydrothermal vents are among the most fascinating environments that exist within modern oceans, being home to highly productive communities of specially-adapted fauna, supported by chemical energy emanating from Earth's subsurface. As hydrothermal have been a feature our planet since Hadean, their history is intricately weaved into life on Earth. Despite an overall scant fossil record due improbabilities preservation vent deposits and organisms, recent findings ancient environments,...
The rehabilitation of legacy mines continues to be a big challenge because the difficulties in returning them safe and stable conditions ensuring that mined-out areas become productive support economic activity host community. Previous efforts are often focused on purely technical environmental aspects, leading resistance from local community due their exclusion process. To address issues associated with lack participation community, we have developed project, Biodiversity Positive Mining...

Abstract There are 19 known fossiliferous volcanogenic massive sulphide (VMS) deposits which range in age from the Silurian to Eocene. Most of these Ural Mountains, Russia. The contain assemblages inarticulate and rhynchonellid brachiopods; gastropod, bivalve monoplacophoran molluscs; a small diversity worm tube morphologies, some may be attributable alvinellid polychaetes vestimentiferans. fossils preserved mainly as external moulds pyrite, is consistent with biomineralization processes...
