Report on geophysical and geological surveys at Blackmount, Argyllshire [PDF]

open access: yes, 1977
Blackmount, on the southern fringe of Rannoch Moor is largely drift covered but, where exposed, the underlying Precambrian Moine psammite contains granitic veins which probably stem from the adjacent (Devonian) Moor of Rannoch granite.

A First Quantification of Plant Endemism in the Manica Highlands (Zimbabwe–Mozambique) and the Significance of Open Habitats

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We present here the first quantitative assessment of plant endemics from the Manica Highlands (Zimbabwe‐Mozambique), totalling 216 taxa, representing over 9% of the estimated total flora. A major finding is that 173 (80%) endemic taxa are principally or entirely confined to open montane habitats such as grassland, bare rock, crags and scrub or dwarf ...

Multistage Neoproterozoic granitic magmatism and formation of Yidong tin deposit in northern Guangxi, China

open access: yesSolid Earth Sciences
A Neoproterozoic tin ore cluster, which is rare for South China, has been discovered in northern Guangxi. The Neoproterozoic granite pluton was formed through multistage magmatism.

High‐Resolution Digital Terrain Model and Land‐Surface Parameters of São Sebastião and Ilhabela, Southeastern Brazil

open access: yesGeoscience Data Journal, Volume 13, Issue 2, April 2026.
The first openly accessible 2 m‐resolution lidar‐based DTM and an extensive set of land‐surface parameters (LSPs) for the region of São Sebastião and Ilhabela, southeastern Brazil, reveal geomorphological features previously indiscernible, including past landslide deposits, drainage captures and structural lineaments.

Paleomagnetism, structure and 40Ar/39Ar geochronology of the Cerro Mercado pluton, Coahuila: Implications for the timing of the Laramide orogeny in northern Mexico

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
The Cerro Mercado pluton, emplaced in the Coahuila fold belt, contains magmatic, ductile, and brittle fabrics that suggest local and regional deformation during igneous emplacement, later affected by regional deformation in the area.

High‐Titanium Zircon Rims in Rhyolite – A Reflection of Adiabatic Ascent?

open access: yesGeological Journal, Volume 61, Issue 4, Page 1029-1040, April 2026.
The ascent of granitic magma from source to emplacement is rapidly achieved through dyking, resulting in negligible heat loss to the surrounding wallrock (i.e., adiabatic). Zircon growth during ascent can record the changing magma conditions including adiabatic cooling and heating, resulting in high titanium rims on low titanium cores without ...
