Embryonic development of the Mediterranean starfish Hacelia attenuata
Developmental Dynamics, EarlyView.Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Metamorphic Geodesic Regression [PDF]
, 2012 We propose a metamorphic geodesic regression approach approximating spatial transformations for image time-series while simultaneously accounting for intensity changes. Such changes occur for example in magnetic resonance imaging (MRI) studies of the developing brain due to myelination.

Testing for the presence of a terrane boundary within Neoproterozoic (Dalradian) to Cambrian siliceous turbidites at Callander, Perthshire, Scotland [PDF]
, 1999 The Southern Highland Group (Dalradian) and Keltie Water Grit Formation, which includes the Lower Cambrian Leny Limestone, form an inverted, 1.4 km thick, largely arenaceous, sequence at Callander.

Geological Journal, EarlyView.Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Imbrication and Erosional Tectonics Recorded by Garnets in the Sikkim Himalayas
Geosciences, 2022 The Sikkim region of the Himalayas (NE India) may form an important microplate between Nepal and Bhutan. Here we report high-resolution pressure-temperature (P-T) paths taken from garnet-bearing rocks across the northern and eastern portion of the region’

Interpretation of the aeromagnetic anomalies of mainland Scotland using pseudogravimetric transformation and other methods [PDF]
, 1990 A procedure to upward continue magnetic anomalies observed on an irregular surface onto a horizontal plane has been developed and applied to the aeromagnetic map of Great Britain.

Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments
Journal of Raman Spectroscopy, EarlyView.Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

Cooling history of the eastern Svecokarelides: whole-rock and mica Rb-Sr and hornblende K-Ar ages in the areas of Pihtipudas-Iisalmi and Joroinen-Sulkava, Finland [PDF]
Bulletin of the Geological Society of Finland, 1990 Rb-Sr age determination on mica and whole-rock samples and K-Ar age determination on hornblendes were carried out to get information on the time of metamorphism and early cooling in two Proterozic areas of the Finnish Svecokarelides.
