Elemental iron (Fe0) for better drinking water in rural areas of developing countries
(
- Uranium, Mining and Hydrogeology
, 2008)
Many of the reasons behind the anthropogenic contamination problems in rural environments of developing countries lie in changes in the traditional way of life and the ignorance on the toxic potential of introduced ...
Texture asymmetries as shear sense indicators in naturally deformed mono- and polyphase carbonate rocks
(
- Textures and microstructures
, 1999)
The microstructural and quantitative texture analyses of a naturally deformed calcite mylonite, a dolomite mylonite and a dolomitic calcite mylonite reveal different texture asymmetries for comparable deformation conditions. ...
MODELING AND SIMULATION OF IRON/SAND FILTERS
(
- Revue des sciences de l'eau
, 2012)
This article develops a mathematical model of Iron (Fe0) /sand filter taking into account the loss of porosity during the filtration process. The mass transport advection-dispersion equation is derived to predict, through ...
Surface velocity fields of active rock glaciers and ice‐debris complexes in the Central Andes of Argentina
(
- Earth Surface Processes and Landforms
, 2020-12-30)
Rock glaciers and transitional ice‐debris complexes predominate the Central Andean landform assemblage, yet regional studies on their state of activity and their kinematics remain sparse. Here we utilize the national glacier ...
Subduction Reversal in a Divergent Double Subduction Zone Drives the Exhumation of Southern Qiangtang Blueschist‐Bearing Mélange, Central Tibet
(
- Tectonics
, 2020-04-04)
(Ultra) high‐pressure (HP) rocks can be exhumed rapidly by subduction reversal or divergent plate motion. Recent studies show that subduction reversal can in particular occur in a divergent double subduction zone when the ...
Revealing Sediment Transport Pathways and Geomorphic Change in Washover Fans by Combining Drone‐Derived Digital Elevation Models and Single Grain Luminescence Data
(
- Journal of Geophysical Research: Earth Surface
, 2021-01-23)
Chronostratigraphic investigations on coastal sedimentary records such as washover fans or beach‐ridge sequences may be used to reconstruct storm chronologies on centennial to millennial time scales. However, modern analogs ...
Ramgarh, Rajasthan, India: A 10 km diameter complex impact structure
(
- Meteoritics & Planetary Science
, 2020)
The Ramgarh structure is a morphological landmark in southeastern Rajasthan, India. Its 200 m high and 3.5–4 km wide annular collar has provoked many hypotheses regarding its origin, including impact. Here, we document ...
Anti‐Phased Miocene Ice Volume and CO2 Changes by Transient Antarctic Ice Sheet Variability
(
- Paleoceanography and Paleoclimatology
, 2020-11-24)
Geological evidence indicates large continental‐scale Antarctic ice volume variations during the early and mid‐Miocene. On million‐year timescales, these variations can largely be explained by equilibrium Antarctic ice ...
New insights into lake responses to rapid climate change: the Younger Dryas in Lake Gościąż, central Poland
(
- Boreas
, 2020-12-16)
The sediment profile from Lake Gościąż in central Poland comprises a continuous, seasonally resolved and exceptionally well‐preserved archive of the Younger Dryas (YD) climate variation. This provides a unique opportunity ...
Reconstructing Depositional Rates and Their Effect on Paleoenvironmental Proxies: The Case of the Lau Carbon Isotope Excursion in Gotland, Sweden
(
- Paleoceanography and Paleoclimatology
, 2020-12-19)
Variations in depositional rates affect the temporal depositional resolutions of proxies used for paleoenvironmental reconstructions; for example, condensation can make reconstructed environmental changes appear very abrupt. ...
