Strengths and limitations of in situ U–Pb titanite petrochronology in polymetamorphic rocks: An example from western Maine, USA
(
- Journal of Metamorphic Geology
, 2022-03-18)
Titanite is a potentially powerful U–Pb petrochronometer that may record metamorphism, metasomatism, and deformation. Titanite may also incorporate significant inherited Pb, which may lead to inaccurate and geologically ...
Inspecting the Reliability of Geochemical Facies Identified for the Waterworks' Capture Zone in Germany
(
- Groundwater
, 2022-01-20)
Little research attention has been given to validating clusters obtained from the groundwater geochemistry of the waterworks' capture zone with a prevailing lake‐groundwater exchange. To address this knowledge gap, we ...
Asteroid 2008 TC3, not a polymict ureilitic but a polymict C1 chondrite parent body? Survey of 249 Almahata Sitta fragments
(
- Meteoritics & Planetary Science
, 2022-05-14)
On October 7, 2008, the asteroid 2008 TC3 exploded as it entered the Earth’s atmosphere, producing significant dust (in the atmosphere) and delivering thousands of stones in a strewn field in Sudan, collectively known as ...
Greigite (Fe3S4) Formation in Artificial Sediments via Solid‐State Transformation of Lepidocrocite
(
- Geochemistry, Geophysics, Geosystems
, 2022-08-12)
Greigite (Fe3S4) is a ferrimagnetic iron‐sulfide mineral that forms in sediments during diagenesis. Greigite growth can occur diachronously within a stratigraphic profile, complicating or overprinting environmental and ...

A Triad Photoanode for Visible Light‐Driven Water Oxidation via Immobilization of Molecular Polyoxometalate on Polymeric Carbon Nitride
(
- Advanced Sustainable Systems
, 2022-03-08)
Due to their availability, low cost, nontoxicity, and tunability, polymeric carbon nitrides (CNx) represent one of the most attractive materials classes for the development of fully sustainable photo(electro)catalytic ...
Olivine aggregates reveal a complex collisional history of the main group pallasite parent body
(
- Meteoritics & Planetary Science
, 2022-04-08)
Olivine aggregates, bodies found in pallasites that consist of olivines with coherent grain boundaries and minor amounts of Fe‐Ni and troilite, likely represent well‐preserved samples of different mantle regions of pallasite ...
Analytical Artefacts Preclude Reliable Isotope Ratio Measurement of Internal Water in Coral Skeletons
(
- Geostandards and Geoanalytical Research
, 2022-07-12)
Internal water in cold‐water and tropical coral skeletons was extracted and measured for its oxygen and hydrogen isotope ratios. Water was extracted by crushing pieces of coral hard tissue in a percussion device connected ...
Arctic – Atlantic Exchange of the Dissolved Micronutrients Iron, Manganese, Cobalt, Nickel, Copper and Zinc With a Focus on Fram Strait
(
- Global Biogeochemical Cycles
, 2022-05-16)
The Arctic Ocean is considered a source of micronutrients to the Nordic Seas and the North Atlantic Ocean through the gateway of Fram Strait (FS). However, there is a paucity of trace element data from across the Arctic ...
Variability in the Concentration of Lithium in the Indo‐Pacific Ocean
(
- Global Biogeochemical Cycles
, 2022-06-22)
Lithium has limited biological activity and can readily replace aluminium, magnesium and iron ions in aluminosilicates, making it a proxy for the inorganic silicate cycle and its potential link to the carbon cycle. Data ...
