Geochemical signature of provenance in sand-size material in soils and stream sediments near the Tobacco Root batholith, Montana, U.S.A.
TLDR
In this paper, Petrologic modal analysis of parent rocks and the 0.25-0.50mm fraction of each sand was done to monitor major mineralogic control, if any, on chemical compositions of the samples.About:

Journal ArticleDOI
The influence of sediment recycling and basement composition on evolution of mudrock chemistry in the southwestern United States
TL;DR: In this paper, the authors report systematic changes in mudrock composition through time on a single con- tinental cmstal block and show that the changes reflect both sediment recycling processes and changes through time in the composition of crystalline material being added to the sedimentary system and are related to tectonic evolution as the block matures from a series of accreted arc terranes to a stable craton.
Journal ArticleDOI
Geochemical and NdSr isotopic composition of deep-sea turbidites: Crustal evolution and plate tectonic associations
TL;DR: In this article, the authors show that trace element abundances of modern turbidites, from both active and passive settings, differ from Archean turbidite in several important ways.
Journal ArticleDOI
The geochemistry of shales, siltstones and sandstones of Pennsylvanian-Permian age, Colorado, USA : implications for provenance and metamorphic studies
TL;DR: In this paper, a series of shales and sandstones found near the source of the Sangre de Cristo, Belden, and Maroon Formations from central Colorado were examined petrographically and were analyzed for major and selected trace elements, including the REE.
Journal ArticleDOI
Geochemistry of ∼1.9 Ga sedimentary rocks from northeastern Labrador, Canada
TL;DR: In this article, the major and minor elements, including C and S, were analyzed for the Ramah Group sedimentary rocks in northeastern Labrador, Canada, to elucidate weathering processes on the Earth's surface about 1.9 Ga ago.
Journal ArticleDOI
Effects of Chemical Weathering and Sorting on the Petrogenesis of Siliciclastic Sediments, with Implications for Provenance Studies
TL;DR: The bulk chemical compositions, mineralogy, and mineral proportions of sands and muds of the Mallacoota Basin in southeastern Australia reflect the composition of weathering profiles mantling source rocks, rather than bedrock as discussed by the authors.

The continental crust: Its composition and evolution
TL;DR: In this paper, the authors describe the composition of the present upper crust and deal with possible compositions for the total crust and the inferred composition of lower crust, and the question of the uniformity of crustal composition throughout geological time is discussed.
Journal ArticleDOI
Plate Tectonics and Geochemical Composition of Sandstones
TL;DR: Sandstones of the Paleozoic turbidite sequences of eastern Australia show a large variation in their major element geochemistry, reflecting the distinct sedimentary provenance and tectonic setting as discussed by the authors.
Journal ArticleDOI
Rare earth element geochemistry of Australian Paleozoic graywackes and mudrocks: Provenance and tectonic control
TL;DR: In the Paleozoic graywackes of eastern Australia there is an increase in the total abundance of rare earth elements (REE), a light to heavy REE ratio and a decrease in the chondrite normalized Eu anomaly with the increase in SiO2/Al2O3 and K2O/Na2O ratios.
Journal ArticleDOI
Instrumental activation analysis of standard rocks with high-resolution γ-ray detectors☆
TL;DR: In this paper, the element abundances in igneous rocks measured by instrumental neutron activation using high resolution lithium drifted germanium detectors were investigated. But the results were limited to a single element.
Journal ArticleDOI
Petrology and Chemistry of Modern Big River Sands
TL;DR: In this article, the sands of the world's modern big rivers were studied to provide a worldwide baseline of their petrology and chemistry, the ultimate objective being to advance our understanding of the tectonic and climatic significance of ancient sandstones.
