Abstract Garnet commonly accommodates high contents of Mn + Y heavy rare earth elements (HREE) that follow Rayleigh fractionation during garnet early growth, with the exception overstepping nucleation (late crystallization owing to reaction overstepping). Because this, as porphyroblasts form mostly in equilibrium surrounding matrix, concentration these continuously decreases towards porphyrobla...

Im draws a parallel between the neurobiology of individuals with autism spectrum disorder (ASD) and that of trauma survivors, to explain why individuals with ASD may be more vulnerable to trauma as a risk factor for violence. This commentary raises questions about how we use this information in a forensic context, including its potential misuses. It urges caution in not overstating the data bef...

A tetrapod trackway from the Lower Pennsylvanian at the historic section at Joggins, Nova Scotia, preserves 13 pairs of impressions with a possible partial tail drag. Although overstepping and poor preservation obscure many of the diagnostic features, the pes is plantigrade to semi-plantigrade and distinctly pentadactyl, with digit length increasing sequentially I-III. The manus may be tetradac...

Different models are discussed to interpret the presence of kyanite as a stable phase in contact aureoles especially in the andalusite-, sillimanitebearing aureoles. In such aureoles the polymorphic sequence kyanite → andalusite → sillimanite can be explained in terms of an essentially isobaric path during which kyanite initially crystallises from the breakdown of pyrophyllite or more likely mu...
