Rhenium-osmium systematics and major and trace element chemistry of cobaltite (CoAsS): Evidence for Late Mesoproterozoic sediment-hosted Co-Cu sulfide mineralization with Grenvillian and Cretaceous remobilization in the Idaho Cobalt Belt, Belt-Purcell Basin, USADownload
We report the first study of the Re-Os systematics of cobaltite (CoAsS) using disseminated andmassively mineralized samples from two breccia-type and two stratabound deposits from the Co-Cu-Au Idaho Cobalt Belt, Lehmi Sub-basin to the Belt-Purcell Basin, Idaho, USA. Using a 185Re+190Os spike...
Re-Os SYSTEMATICS OF LOELLINGITE AND ARSENOPYRITE IN GRANULITE-FACIES GARNET ROCKS: INSIGHTS INTO THE METAMORPHIC HISTORY AND THERMAL EVOLUTION OF THE BROKEN HILL BLOCK DURING THE EARLY MESOPROTEROZOIC (NEW SOUTH WALES, AUSTRALIA)Download
Loellingite and arsenopyrite aggregates occur in spessartine-almandine garnet rocks (garnetite) metamorphosed to granulite facies, which are spatially associated with Pb-Zn-Ag mineralization in the giant Broken Hill deposit, southern Curnamona Province, New South Wales, Australia. Sulfarsenide...
A winter city is any urban centre that experiences a long, dark, cold, and/or snowy winter. The Winter Cities movement is a more precise concept, referring to cities taking an active role in becoming more appealing and functional in winter, primarily through physical interventions. The movement...
We experimentally investigate the behaviour of a line-source plume falling through a finite two-layer stratified ambient where the depth of the upper ambient layer increases in time. Laboratory observations suggest one of two possible flow regimes depending on the value of 𝜆 , which represents...
Cenozoic ‘island dolostones’ are found on islands throughout the oceans of the world. Due to their geological youth and lack of deep burial, these dolostones provide an opportunity to resolve some of the mysteries surrounding the dolomite problem. In island dolostone bodies, which are of variable...
Temporal and environmental significance of microbial lamination: insights from Recent fluvial stromatolites in the River Piedra, Spain.Download
Despite extensive research, the environmental and temporal significance of microbial lamination is still ambiguous because of the complexity of the parameters that control its development. A 13 year monitored record of modern fast‐accreting calcite stromatolites (mean 14 mm year−1) from...
Diagenetic overprint on negative <delta>13C excursions across the Permian/Triassic boundary: A case study from Meishan section, China.Download
The Meishan Section D from China is the global stratotype section and point (GSSP) of the Permian-Triassic boundary (PTB). The succession has been divided into 115 beds with the PTB being placed in the middle of Bed 27. In this section and the laterally equivalent Section A, the diagenetic...
Many spring deposits throughout the world are characterized by spectacular deposits of calcium carbonate that are formed of various combinations of aragonite and calcite, and in very rare cases vaterite. The factors that control the precipitation of the aragonite and calcite have been the subject...
Modern travertine precipitation at Lýsuhóll hot springs, Snæfellnes, Iceland: implications for calcite crystal growth.Download
Three thermal springs, at Lýsuhóll on Snæfellnes Peninsula on the west coast of Iceland, with vent water temperatures of 20 to 46°C are characterized by thriving microbial mats that mediate the precipitation of opal-A, Fe-rich opal-A, Fe-rich reticulate coatings, and calcite that are intermixed...
Age, origin, and thermal evolution of the ultra-fresh ~1.9 Ga Winnipegosis Komatiites, Manitoba, CanadaDownload
The Proterozoic spans the longest portion of earth's history, yet in contrast to the Archaean, the record of komatiites and related high MgO igneous rocks from this Eon is sparse. This paper describes the pristine Palaeoproterozoic Winnipegosis Komatiites, from Manitoba, Canada, which form part...
