Mercury's geochronology revised by applying Model Production Functions to Mariner 10 data: geological implications [PDF]
Model Production Function chronology uses dynamic models of the Main Belt Asteroids (MBAs) and Near Earth Objects (NEOs) to derive the impactor flux to a target body.

The Labrador Sea is a small (∼900 km wide) ocean basin separating southwest Greenland from Labrador, Canada. It opened following a series of rifting events that began as early as the Late Triassic or Jurassic, culminating in a brief period of seafloor ...

The older ultramafic rocks of Aberdeenshire, similarities to SSZ ophiolites and significance for regional tectonics [abstract] [PDF]
It has long been known that there are at least two phases of mafic-ultramafic magmatism in NE Scotland (Read 1919), the well known Younger Gabbro suite and a lesser known ‘Older suite’.

Sea-floor tectonics and submarine hydrothermal systems [PDF]
The discovery of metal-depositing hot springs on the sea floor, and especially their link to chemosynthetic life, was among the most compelling and significant scientific advances of the twentieth century. More than 300 sites of hydrothermal activity and

Granite magmatism and mantle filiation
Abstract. Current granite magma generation models essentially reduce to two groups: (1) intra-crustal melting and (2) basaltic origin. A mixed, crustal, and basaltic origin and therefore a mantle filiation has been proposed for most granite magma types.

The area of studies covers the north-eastern part of the Siberian craton (the Birekte terrain), Russia. The influence of metasomatic and magmatic processes on the mantle lithosphere is studied based on results of analyses of phlogopite- and phlogopite ...

Rifted margins form from extension and breakup of the continentallithosphere. If this extension is coeval with a region of hotter lithosphere,then it is generally assumed that a volcanic margin would follow.
