ATMOSPHERIC DUST FROM THE UPPER CARBONIFEROUS COPACABANA FORMATION (BOLIVIA): A HIGH-RESOLUTION RECORD OF CLIMATE AND VOLCANISM FROM NORTHWESTERN GONDWANA
(2016-08-19)This study documents the occurrence of atmospheric dust from Pennsylvanian carbonates of the Copacabana Formation, recovered in core (Mobil-Oxy Manuripi X-1) from the Madre de Dios basin (Bolivia), within southern mid-latitudes ... -
Giant grains in the Akiyoshi Limestone: A record of atmospheric circulation over the Panthalassic Ocean
(2021)Models indicate that atmospheric transport distances for large windblown particles are limited to tens to perhaps hundreds of km owing to rapid gravitational settling, yet a number of studies of modern–recent sediment have ... -
AN ICEHOUSE DUST RECORD FROM THE UPPER PALEOZOIC (ASSELIAN-ARTINSKIAN, MOSCOVIAN) AKIYOSHI LIMESTONE (JAPAN)
(2016)The Akiyoshi terrane in southwest Japan consists of a subduction-generated accretionary complex of shallow-marine limestone and deep-water spicular chert, underlain by ocean island-type basalt, all of which was obducted ... -
A PALEOCLIMATE AND PALEOFIRE HISTORY FROM THE EARLY PLEISTOCENE OF UNAWEEP CANYON, NORTHWESTERN COLORADO
(2024-05)Lacustrine systems capture high-resolution records of continental climate, including information on paleotemperatures, hydroclimate, and paleofire activity. An increasing number of studies have reported paleoclimate and ... -
A RECORD OF MID-LATITUDE DUSTINESS IN A CARBONIFEROUS-PERMIAN CARBONATE RAMP ON CENTRAL SPITSBERGEN
(2018)This study focuses on a mid-latitude dust record from the Wordiekammen Formation, a carbonate ramp on Spitsbergen. The ramp developed on the Northern Pangean margin in Moscovian (Carboniferous) through Sakmarian (Permian) ... -
Variation in time averaging and taphonomic character of shell beds in Lake Tanganyika, Africa: Paleoenvironmental and stratigraphic implications of shell beds in rift lakes
(2018-05-11)Large regions of the littoral lake bottom along structural platforms in Lake Tanganyika, Africa, are carpeted with shell beds of late Holocene age. The viviparous gastropod Neothauma tanganyicense (Neothauma) is the lead ...
