First records of syn-diagenetic non-tectonic folding in Quaternary thermogene travertines caused by hydrothermal incremental veining.
Download2017-01-01
Alçiçek, M.C., Alçiçek, H., Altunel, E., Arenas, C., Bons, P., Brogi, A., Capezzuoli, E., de Riese, T., Della Porta, G., Gandin, A., Guo, L., Jones, B., Karabacak, V., Kershaw, S., Liotta, D., Mindszenty, A., Pedley, M., Ronchi, P., Swennen, R., Temiz, U.
This study is the first documentation of syn-diagenetic non-tectonic contractional deformations observed in two Pleistocene thermogene travertine deposits from the late Miocene-Pleistocene Tuscan extensional-hydrothermal province (Italy). The deposits consist of primary porous beds hosting...

First-principles calculations of equilibrium nitrogen isotope fractionations among aqueous ammonium, silicate minerals and salts
Download2021-03-15
Li, Yonghui, Li, Long, Wu, Zhongqing
Nitrogen isotopes are a robust tool to study geological nitrogen cycle between Earth’s reservoirs. However, the application of nitrogen isotope system to understanding geological processes has been limited by the lack of constraints on equilibrium isotope fractionation factors between mineral and...

A series of experiments with an ocean general circulation model of the Mediterranean forced by artificial (but realistic) surface fluxes of heat and freshwater are performed. The model has a stable thermohaline circulation under the baseline fluxes. Small decreases in excess evaporation (8%)...

Formation of mixed paragenesis diamonds during multistage growth – constraints from in situ δ 13C–δ 15N–[N] analyses of Koidu diamonds
Download2022-01-01
Lai, Mei Yan, Stachel, Thomas, Stern, Richard A., Hardman, Matthew F., Pearson, D. Graham, Harris, Jeff W.
Abstract Inclusion-bearing diamonds from the Koidu kimberlite complex, Sierra Leone (West African Craton) were analyzed in situ for carbon and nitrogen isotope compositions, nitrogen concentrations and nitrogen aggregation states. In a suite of 105 diamonds, 78% contain eclogitic mineral...

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...

Greenland freshwater pathways in the sub-Arctic seas from model experiments with passive tracers
Download2016
Chassignet, Eric, Lee, Craig M., Bamber, Jonathan L., Curry, Beth, Dukhovskoy, Dmitry S., Timmermans, Mary-Louise, Platov, Gennady, Myers, Paul G., Proshutinsky, Andrey, Hu, Xianmin, Somavilla, Raquel
Accelerating since the early 1990s, the Greenland Ice Sheet mass loss exerts a significant impact on thermohaline processes in the sub-Arctic seas. Surplus freshwater discharge from Greenland since the 1990s, comparable in volume to the amount of freshwater present during the Great Salinity...

Throughout the world, high artesian pressures in hydrothermal areas have led to the growth of tall spring towers that have their vents at their summits. The factors that control their development and formative precipitates are poorly understood because these springs, irrespective of location, are...

Muller, Vasco, Kieke, Dagmar, Myers, Paul G., Pennelly, Clark, Steinfeldt, Reiner, Stendardo, Ilaria
A new data set of temperature and salinity fields reconstructed from satellite altimetry data between January 1993 and April 2014 is combined with satellite observations of mesoscale eddies in the subpolar North Atlantic between 40°N–55°N and 43°W–20.5°W. The data set is used to calculate the...

The notion that Housing First (HF) is a human-rights based approach to housing some of society’s most vulnerable citizens is often alluded to in the literature, but seldom interrogated. In this paper, we examine whether HF in Alberta, Canada is practiced in a way that realizes the right to...

Hudson Strait is the main pathway of heat, mass, and freshwater exchange between Hudson Bay and the Arctic and North Atlantic oceans. The outflow along the southern coast of the strait, a fresh, baroclinic jet directed toward the North Atlantic, has received more attention due to its potential...
