TL;DR: The major element compositions of the various rocks that belong to the basalt clan are examined in this article, where the authors define basalt clans as consisting of those volcanic rocks that contain between 44.0% and 53.5% silica.

TL;DR: In this paper, the authors discuss the shear resistance of granular water-saturated sediments within the constraints imposed by the Coulomb model of shear failure, and the phenomena of thixotropy, liquefaction, retrogressive flow sliding and fluidization are discussed as mechanisms for producing the mass mobilization of sediment.

TL;DR: Carey, S W, 1975 The expanding earth -- an essay rewew Earth-Sc, Rev, 11 105--143 The Wegener bombshell of gross continental separation promptly triggered the concept of earth expansion as an alternative to drift, but books m German by Lmdemann (1927), Bogolepow (1930), Hllgenberg (1933), and Kemdl (1940) got httle attention in the Enghsh hterature as discussed by the authors.

TL;DR: Boudda et al. as mentioned in this paper proposed principles for the definition of the boundary based on those accepted by the Commission on Stratigraphy, particularly on stratigraphic classification and on defining the Silurian-Devonian boundary.

TL;DR: In this paper, the authors introduce the island arc series, front to rear, of tholeiitic to calcalkaline to high potash rocks, with concomitant geochemical indices, and provide new insights into the genesis, mode of formation, behaviour and ultimate fate of island arcs.

TL;DR: Since the discovery that ionizing tracks left by highly energetic nuclei can be made visible through optical microscopes by proper etching, the field of particle track studies has blossomed at a rate equalled only by the growth of the porno-film industry as mentioned in this paper.

TL;DR: The control of the chemical composition of seawater can be studied from a geochemical point of view, in which the ocean is only one of several linked reservoirs, by traditional oceanographic methods which concentrate upon processes within and at the boundaries of the oceans, or by physicochemical approach which deals with the extent and rate of chemical reactions.

TL;DR: The Mesozoic-Tertiary orogens of the earth's crust are discussed in detail in this article and a relativistic analysis of the deformations and transformations of the lithospheric frame around these younger orogens is presented.
