How American Mineralogist and the Mineralogical Society of America influenced a career in mineralogy, petrology, and plate pushing, and thoughts on mineralogy's future role
Autor: W. G. Ernst
Publikováno v: American Mineralogist. 105:1285-1296
My geologic research began at Carleton College. I studied heavy minerals in some midcontinent orthoquartzites, publishing my very first paper in American Mineralogist in 1954. As a master's candidate at the University of Minnesota, I investigated ign

U-Pb detrital zircon ages of Cambrian–Ordovician sandstones from the Taebaeksan Basin, Korea: Provenance variability in platform shelf sequences and paleogeographic implications
Autor: W. G. Ernst, Wonseok Cheong, Yoonsup Kim, Keewook Yi, Moonsup Cho
Publikováno v: GSA Bulletin. 133:488-504
The early Paleozoic paleogeography of East Gondwanan terranes, including the North China Craton (NCC), is contentious, primarily reflecting the paucity of integrated geochronological, biogeographic, and tectonic data sets. Our new sensitive high-reso

Petrotectonic origin of mafic eclogites from the Maksyutov subduction complex, south Ural Mountains, Russia
Autor: Theodore D. Burlick, Mary L. Leech, W. G. Ernst, Andrey A. Shchipansky, Valentin V. Fedkin, Peter M. Valizer
The Maksyutov complex is a mid- to late-Paleozoic high- to ultrahigh-pressure (HP-UHP) eclogite-bearing subduction zone terrane in the south Ural Mountains. Previous reports of radial fractures emanating from quartz inclusions in garnet, omphacite, a

SHRIMP U-Pb ages of zircons from mafic granulites of the Eastern Ghats Belt, SE India: Implications for the evolution of the palaeoproterozoic arc crust
Autor: W. G. Ernst, K. Vijaya Kumar, C. Leelanandam, Joseph L. Wooden
Publikováno v: Journal of Asian Earth Sciences. 177:198-219
We determined SHRIMP U-Pb ages of zircons from three mafic granulite samples of the polymetamorphosed, multiply-deformed Kondapalli-Ongole domain of the Eastern Ghats Belt (EGB), SE India. Our goals are: (1) to evaluate the origin of zircons in the h

Paleozoic granitic magmatism and tectonic evolution of the South Altun block, NW China: Constraints from zircon U-Pb dating and Lu-Hf isotope geochemistry
Autor: Hongjie Chen, W. G. Ernst, Cailai Wu, Di Wu
Publikováno v: Journal of Asian Earth Sciences. 160:168-199
The South Altun orogenic belt (SAOB), consisting of the South Altun block (SAB) and the South Altun continental block (SACB), is one of several important orogenic belts in NW China. Numerous granite bodies are widely distributed in the SAB. However,

Characteristics and implications of podiform-chromite hosted silicate inclusions in the Zedang ophiolite, Southern Tibet
Autor: Juhn G. Liou, Jingsui Yang, Wendy L. Mao, Bin Wu, W. G. Ernst, Yong Zhang, Ru Y. Zhang, Xiangzhen Xu, Guolin Guo, Xiaodong Liu
Publikováno v: Lithos. :106218
The Zedang ophiolite, containing pods of massive chromitite, crops out in the eastern segment of the Yarlung-Zangbo suture zone, Southern Tibet. Chromite grains in the Zedang chromitite bodies have high Cr# [Cr/(Cr + Al)] (0.73–0.82) and Mg# [Mg/(M

Earth’s thermal evolution, mantle convection, and Hadean onset of plate tectonics
Autor: W. G. Ernst
Publikováno v: Journal of Asian Earth Sciences. 145:334-348
During Solar System condensation, the early Earth formed through planetesimal accretion, including collision of a Mars-sized asteroid. These processes rapidly increased the overall thermal budget and partial fusion of the planet. Aided by heat suppli
