Geochemical and NdSr isotopic composition of deep-sea turbidites: Crustal evolution and plate tectonic associations
TLDR
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.About:

The geochemical evolution of the continental crust
TL;DR: A survey of the dimensions and composition of the present continental crust is given in this paper, where it is concluded that at least 60% of the crust was emplaced by the late Archean (ca. 2.7 eons).

The chemical composition of subducting sediment and its consequences for the crust and mantle
Terry Plank,Charles H. Langmuir +1 more
TL;DR: This article evaluated subducting sediments on a global basis in order to better define their chemical systematics and to determine both regional and global average compositions, and then used these compositions to assess the importance of sediments to arc volcanism and crust-mantle recycling, and to re-evaluate the chemical composition of the continental crust.
Journal ArticleDOI
Chemical composition and evolution of the upper continental crust: Contrasting results from surface samples and shales
TL;DR: The average chemical composition of the upper continental crust (UC) as a function of age is estimated from chemical analyses, geologic maps, stratigraphic sections and isotopic ages as discussed by the authors.
Journal ArticleDOI
Relationships between the trace element composition of sedimentary rocks and upper continental crust
TL;DR: In this paper, the upper crustal abundances of several trace elements, including rare earth elements (REEs), were compared to the upper continental crust of the United States, and the results showed that no revisions are needed for these elements.
Journal ArticleDOI
Evolution of the depleted mantle: Hf isotope evidence from juvenile rocks through time
TL;DR: In this article, the covariant behavior of Lu-Hf and Sm-Nd isotopes during most magmatic processes has been recognized, but the details of this behavior in the depleted mantle reservoir have not been adequately examined.

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
Early Proterozoic climates and plate motions inferred from major element chemistry of lutites
H.W. Nesbitt,Grant M. Young +1 more
TL;DR: The early Proterozoic Huronian Supergroup of the north shore of Lake Huron (Fig. 1) is a thick succession of sedimentary and volcanic rocks deposited between about 2,500 and 2,100 Myr ago as discussed by the authors.
Journal ArticleDOI
World-Wide Delivery of River Sediment to the Oceans
John D. Milliman,Robert H. Meade +1 more
TL;DR: The authors showed that rivers with large sediment loads (annual discharges greater than about $15 \times 10^{6}$ tons) contribute about $7 −times 10 −9$ tons of suspended sediment to the ocean yearly.

Orogenic Andesites and Plate Tectonics
TL;DR: In this article, the authors define Orogenic Andesite and discuss its properties and properties, including the following: 1.1 Topography, gravity, heat flow, and conductivity.

Trace element characteristics of graywackes and tectonic setting discrimination of sedimentary basins
Mukul R. Bhatia,Keith A.W. Crook +1 more
TL;DR: In this article, a large variation in trace element characteristics of graywackes of the Paleozoic turbidite sequences of eastern Australia show a large increase in light rare earth elements (La, Ce, Nd), Th, Nb and the Ba/Sr, Rb, Sr, La/Y and Ni/Co ratios.
