The geochemical signatures of subducting crust have been identified in various types of
mafic igneous rocks at convergent plate boundaries, where island arc basalts (IAB) and …

Orogeny, the process by which the earth's prominent mountain ranges are constructed, has
been a central topic of interest in the earth sciences since at least the end of the 18th …

A map of the ocean basins (Fig. 5.1) shows that their most conspicuous topographic feature
is the system of mid-oceanic ridges, the crests of which rise on average 1000-3000 m above …

The petrogenesis of trondhjemite‐tonalite‐dacite (TTD) involves all major petrologic models
in various tectonic settings. A specific subtype of TTD, high‐Al type, is the one most …

The phase relations of primitive magnesian andesites and basaltic andesites from the Mt.
Shasta region, N California have been determined over a range of pressure and …

The third edition of this widely acclaimed textbook provides a comprehensive introduction to
all aspects of global tectonics, and includes major revisions to reflect the most significant …

大地构造相是反映陆块区和造山系(带) 形成演变过程中, 在特定演化阶段, 特定构造部位的大地
构造环境中, 形成的一套岩石-构造组合, 是表达大陆岩石圈板块经过离散, 聚合碰撞 …

Abstract We present Hf, Nd and Sr isotopic data and abundances of K, Rb, Cs, Ba, Sr, Hf and
REE for 32 samples from seven intra-oceanic island arcs. Samples from the Marianas, Izu …

Abstract New 40 Ar/39 Ar, geochemical and Srsingle bond Nd isotopic analyses of Eocene–
Oligocene magmatic rocks in the Lut–Sistan region, eastern Iran shed light on their origin …

Subduction zones appear primarily controlled by the polarity of their direction, ie, W-directed
or E-to NNE-directed, probably due to the westward drift of the lithosphere relative to the …
