Magmatic trees: a method to compare processes between igneous systems

Volcanica
This paper presents the motivation, instructions, and applications for a new graphical method to construct ‘magmatic trees’, which summarize the petrologic and geochemical processes that formed a particular igneous rock unit or eruption.

International Dermoscopy Society consensus recommendations for the management of lentigo maligna

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Lentigo maligna (LM) poses diagnostic and therapeutic challenges amid rising incidence and limited high‐quality evidence. This international expert consensus provides pragmatic, evidence‐based and expertise‐informed guidance on LM diagnosis and management.

Porphyry copper formation driven by water-fluxed crustal melting during flat-slab subduction [PDF]

The prevailing view of the formation of porphyry copper deposits along convergent plate boundaries involves deep crustal differentiation of metal-bearing juvenile magmas derived from the mantle wedge above a subduction zone.

Petrogenesis of late triassic high-silica granites in the North Qiangtang terrane, central Tibetan Plateau

Frontiers in Earth Science
Although high-silica granites can provide unique insights into the maturity of the continental crust and rare metal enrichment, the origin of high-silica granitic magmatism remains uncertain.

An investigation into the diet of elephant fish (Callorhinchus milii) in the waters of Aotearoa/New Zealand

Journal of Fish Biology, EarlyView.
Abstract Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters.

Geology and petrology of the margin of the Rhum ultrabasic intrusion, Inner Hebrides, Scotland

, 2015
Country rocks surrounding the Rhum Tertiary ultrabasic complex have experienced severe thermal metamorphism, partial melting and mobilization resulting in the formation of extensive areas of intrusion breccia.

Variable Sr Diffusion and Implications for Rb–Sr Biotite Geochronology

Journal of Metamorphic Geology, EarlyView.
ABSTRACT The rubidium–strontium (Rb–Sr) system has a long pedigree as a geochronological tool that relies on the application of an isochron approach. In particular, biotite contains strongly radiogenic Rb–Sr isotopes, and thus can yield meaningful crystallisation or cooling ages via this approach. However, the response of the Rb–Sr system in biotite to

Heterogeneous crust and upper mantle across southern Kenya and the relationship to surface deformation as inferred from magnetoteluric imaging. [PDF]

, 2007
We have used magnetotelluric data imaging to determine the resistivity structure across southern Kenya and our results suggest the presence of a buckled blocky or segmented lithosphere across the region.

P–T Modelling Constrains the Depth of Emplacement of the Porto Azzurro Pluton and Implies Minor Exhumation Caused by the Zuccale Fault (Island of Elba, Italy)

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Understanding the pressure of emplacement of granitic intrusions is crucial to understanding the exhumation history of plutons and constraining the tectonic setting of magma emplacement. However, P–T and geochronological constraints from exhumed plutons are often characterized by large uncertainties, especially in shallow crustal settings with
