The end of the Archean aeon (3.0–2.5 Ga) was a period of fundamental change in many
aspects of the geological record. In Archean cratons, this timespan is marked by a …

TTGs (tonalite–trondhjemite–granodiorite) are one of the archetypical lithologies of
Archaean cratons. Since their original description in the 1970s, they have been the subject …

The lower plate is the dominant agent in modern convergent margins characterized by
active subduction, as negatively buoyant oceanic lithosphere sinks into the asthenosphere …

The generation, preservation and destruction of continental crust on Earth is of wide interest
in understanding the formation of continents, cratons and supercontinents as well as related …

A survey is given of the dimensions and composition of the present continental crust. The
abundances of immobile elements in sedimentary rocks are used to establish upper crustal …

内容提要: 本文讨论和评述火成岩常用图解, 包括火成岩分类命名, 岩石的化学参数与构造环境
判别图解, 原作者构建时的岩石学含义与随后文献中应用时的各种误解, 或不同学者对相同参数 …

Examination of an extensive adakite geochemical database identifies two distinct
compositional groups. One consists of high-SiO2 adakites (HSA) which is considered to …

The continental crust has an andesitic bulk composition, which cannot have been produced
by the basaltic magmatism that dominates sites of present-day crustal growth—at both …

A significant change in the composition of turbidites deposited at active tectonic settings is
seen at the Archean/post-Archean transition. In comparison to post-Archean active margin …

Abstract Analysis of δ 18 O in igneous zircons of known age traces the evolution of
intracrustal recycling and crust-mantle interaction through time. This record is especially …
