The Earth as a planetary system has experienced significant change since its formation c.
4.54 Gyr ago. Some of these changes have been gradual, such as secular cooling of the …

This work examines the global distribution of Archaean and modern igneous rock's
compositions, without relying on preconceptions about the link between rock compositions …

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

Plate tectonics, involving a globally linked system of lateral motion of rigid surface plates, is
a characteristic feature of our planet, but estimates of how long it has been the modus …

Detrital zircon spectra reflect the tectonic setting of the basin in which they are deposited.
Convergent plate margins are characterized by a large proportion of zircon ages close to the …

The Earth is the only known planet where plate tectonics is active, and different studies have
concluded that plate tectonics commenced at times from the early Hadean to 700 Ma. Many …

The classical approach to sandstone petrology, established in the golden years of plate
tectonics and based on the axiom that “detrital modes of sandstone suites primarily reflect …

Students of a phenomenon as common but complex as andesite genesis often are
overwhelmed by, or overlook, the volume and diversity of relevant information. Thus there is …

In this paper, a new discrimination diagram using absolute measures of Th and Nb is
applied to post-Archean ophiolites to best discriminate a large number of different ophiolitic …
