Facies and evolution of the carbonate factory during the Permian–Triassic crisis in South Tibet, China [PDF]

, 2019
The nature of Phanerozoic carbonate factories is strongly controlled by the composition of carbonate-producing faunas. During the Permian–Triassic mass extinction interval there was a major change in tropical shallow platform facies: Upper Permian ...

Time-space focused intrusion of genetically unrelated arc magmas in the early Paleozoic Ross-Delamerian Orogen (Morozumi Range, Antarctica) [PDF]

, 2015
The growth of continental crust in accretionary orogenic belts takes place through repeated cycles of subduction– accretion of rock units fromcontinental and oceanic magmatic arcs, supra-subduction zone backarcs and forearcs loaded with continent ...

Wetland occupancy by duck broods in cropland‐dominated landscapes of the United States Prairie Pothole Region

The Journal of Wildlife Management, Volume 87, Issue 2, February 2023., 2023
We evaluated how wetland occupancy by duck broods varied across crop‐dominated landscapes of the Prairie Pothole Region (PPR) in the United States to inform conservation strategies in the face of widespread land use alterations and climate change. We found about 4 in 10 small wetlands in crop‐dominated landscapes within the PPR were used by duck broods

Comparison of the Thermometery-Barometery methods by using Thermocalc and Theriak-domino to study Calc- silicate Hornfelses in Cheshin, Hamedan

Journal of Economic Geology, 2019
Introduction The pseudo-section method, first proposed by Hensen (1971), is used today by scientists to determine the thermodynamic conditions of mineral crystallization and modeling in metamorphic lithology (Hoschek, 2004; Omrani et al., 2013).

Cost‐effective in‐mine seismic experiments to image platinum deposits and associated geological structures at Maseve platinum mine, South Africa

Near Surface Geophysics, Volume 20, Issue 6, Page 572-589, December 2022., 2022
ABSTRACT The detection of mineral deposits and their related geological structures is of great importance to the mining industry as structures (such as dykes and faults) can affect the safety, cost and efficiency of mining. With the goal of testing cost‐effective seismic methods for mineral exploration and mining, active and passive seismic experiments

Paleogene initiation of the Western Branch of the East African Rift: The uplift history of the Rwenzori Mountains, Western Uganda [PDF]

, 2020
The two branches of the East African Rift System (EARS) are believed to have initiated diachronously. However, a growing body of work continues to suggest the onset of rifting in the Western Branch occurred in the Paleogene, coeval to the Eastern Branch.

Characterization and Reuse of Lithium‐ion Battery Cathode Material Recovered Through a Bacterial Process

Advanced Energy Materials, EarlyView.
A sustainable bacteria‐based lithium‐ion battery cathode recycling method is optimized using engineering biology. The resulting biomineralized manganese carbonate species is found to be easily converted into an electrode material, via simple calcination.

An Improved IASI Temperature and Humidity Retrieval Method Based on Double Channel Differences

Earth and Space Science, Volume 9, Issue 12, December 2022., 2022
Abstract Due to surface emissivity, the retrieval accuracy of hyperspectral infrared temperature and humidity profiles is typically poor in the lower atmosphere. To solve this problem, we use the double channel differences method (DCDM) to retrieve the temperature and humidity profiles of the Infrared Atmospheric Sounding Interferometer (IASI) with ...
