recommendations! Published in 2017 at "Journal of Asian Earth Sciences"

DOI: 10.1016/j.jseaes.2017.04.015

Abstract: Abstract The Mesoproterozoic Ampani Group of rocks, a structurally deformed sedimentary package hosted within the Bastar Craton in central India, was studied for process-based facies and paleoenvironmental analyses. Outcrop mapping on 1:1500 scale, deconvolution of… read more here.

DOI: 10.1016/j.jseaes.2019.04.013

Abstract: Abstract Extensive Mesoproterozoic magmatism occurred in the Karbi Hills Massif, NE India, providing a key to understanding the early geodynamic evolution of Karbi Craton during the Columbia (Nuna) supercontinent cycle. We present here LA-ICP-MS zircon… read more here.

DOI: 10.1016/j.precamres.2017.12.022

Abstract: Abstract Samples of red bed sediments in several Mesoproterozoic successions contain enrichments of tellurium (Te), including discrete telluride minerals. The tellurides were neoformed during redox-controlled diagenesis, rather than representing mechanical concentrations of heavy minerals. Tellurium… read more here.

DOI: 10.1016/j.precamres.2020.105718

Abstract: Abstract Fundamental questions persist regarding the redox structure and trace metal content of the Mesoproterozoic oceans. Multiple lines of evidence suggest more widespread anoxia in the deep oceans compared to today, and iron speciation indicates… read more here.

DOI: 10.1016/j.precamres.2021.106154

Abstract: Abstract Controversial issues on the Paleo-Mesoproterozoic tectonic setting of the southern margin of North China Craton (NCC) restricted our understanding of its role in breaking up the Columbia/Nuna Supercontinent. Existing models are still arguing on… read more here.
