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)

NJ Saintilan, RA Creaser, PG Spry
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...

Recent increases in Arctic freshwater flux affects Labrador Sea convection and Atlantic overturning circulation
Download2016
Chambers, Don, Dixon, Timothy H., Bonin, Jennifer, van den Broeke, M. R., Yang, Qian, Ribergaard, Mads H., Mortensen, John, Myers, Paul G.
The Atlantic Meridional Overturning Circulation (AMOC) is an important component of ocean thermohaline circulation. Melting of Greenland’s ice sheet is freshening the North Atlantic; however, whether the augmented freshwater flux is disrupting the AMOC is unclear. Dense Labrador Sea Water (LSW),...

Recommendations for offline combustion-based nitrogen isotopic analysis of silicate minerals and rocks
Download2021-03-01
Li, Long, Li, Kan, Li, Yingzhou, Du, Yifan, Labbe, Mark
Rationale Due to isotope fractionations during partial nitrogen release from minerals and rocks, the complete extraction of nitrogen for analysis is crucial to ensure high-quality nitrogen isotopic data. However, the appropriate nitrogen extraction conditions (e.g. temperature, duration) have not...

Response of the Mediterranean Sea thermohaline circulation to observed changes in the winter wind stress field in the period 1980-1993
Download1999
Josey, Simon, Samuel, Sarah, Myers, Paul G., Haines, Keith
This paper seeks to model changes in deep water production in the eastern Mediterranean induced by changes in winter wind stress. An analysis of individual monthly wind stress fields over the Mediterranean for 1980–1993 from the SOC flux data set shows that an intensification of the winter mean...

Melim, Leslie A., Northup. Diana E., Spilde, Michael N., Jones, Brian, Boston, Penelope J., Bixby, Rebecca J.
We report on a reticulated filament found in modern and fossil cave samples that cannot be correlated to any known microorganism or organism part. These filaments were found in moist environments in five limestone caves (four in New Mexico, U.S.A., one in Tabasco, Mexico), and a basalt lava tube...

Aragonite and calcite crystals are the fundamental building blocks of calcareous thermal spring deposits. The diverse array of crystal morphologies found in these deposits, which includes monocrystals, mesocrystals, skeletal crystals, dendrites, and spherulites, are commonly precipitated under...

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...

Ridenour, Natasha A., Hu, Xianmin, Sydor, Kevin, Myers, Paul G., Barber, David G.
The Hudson Bay Complex is the outlet for many Canadian rivers, receiving roughly 900 km3/year of river runoff. Historically, studies found a consistent cyclonic flow year-round in Hudson Bay, due to the geostrophic boundary current induced by river discharge and cyclonic wind forcing that was...

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, USA
Download2019-01-07
NJ Saintilan, RA Creaser, AA Bookstrom
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...

Smith, Gregory C., Yashayaev, Igor, Saenko, Oleg A., Dupont, Frédéric, Myers, Paul G., Yang, Duo
Deep convection in the Labrador Sea is an important component of the global ocean ventilation. The associated loss of heat to the atmosphere from the interior of the sea is thought to be mostly supplied by mesoscale eddies, generated either remotely or as a result of convection itself—processes...
