An analytic mean-field $\alpha^2$-dynamo with a force-free corona [PDF]

open access: yes, 2017
Stellar dynamos are affected by boundary conditions imposed by stellar coronae. Under some approximations it is possible to find analytical solutions.

Late Precambrian U-Pb titanite age for peak regional metamorphism and deformation (Knoydartian orogeny) in the western Moine, Scotland [PDF]

open access: yes, 2003
There has been controversy over the number and timing of orogenies in the Precambrian Moine block in the Scottish Caledonides since the earliest radiometric dating in the 1960s. This work challenges a recent hypothesis, that this sector of the Laurentian

Magma oceans and enhanced volcanism on TRAPPIST-1 planets due to induction heating

open access: yes, 2017
Low-mass M stars are plentiful in the Universe and often host small, rocky planets detectable with the current instrumentation. Recently, seven small planets have been discovered orbiting the ultracool dwarf TRAPPIST-1\cite{Gillon16,Gillon17}. We examine

An Evaluation of Proposed Mechanisms of Slab Flattening in Central Mexico [PDF]

open access: yes, 2010
Central Mexico is the site of an enigmatic zone of flat subduction. The general geometry of the subducting slab has been known for some time and is characterized by a horizontal zone bounded on either side by two moderately dipping sections.

A Common Origin for Ridge-and-Trough Terrain on Icy Satellites by Sluggish Lid Convection [PDF]

open access: yes, 2015
Ridge-and-trough terrain is a common landform on outer Solar System icy satellites. Examples include Ganymede's grooved terrain, Europa's gray bands, Miranda's coronae, and several terrains on Enceladus.

Ultra - high temperature granulite - facies metamorphic rocks from the Mozambique belt of SW Tanzania [PDF]

open access: yes, 2013
The metamorphic rocks in the Neoproterozoic (Pan-African) Mozambique belt of southwestern Tanzania, around the town of Songea, can be subdivided into one- and two pyroxene bearing charnockitic gneisses, migmatitic granitoid gneisses and amphibolite ...

Geologic Map of the Ganiki Planitia Quadrangle (V–14), Venus [PDF]

open access: yes, 2011
Our current research focuses on addressing four specific questions. Has the dominant style of volcanic expression within the quadrangle varied in a systematic fashion over time?
