Paleomagnetic dating of rocks of the Bolshesyrsky magmatic area of the Minusinsky basin

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле
Paleomagnetic dating of the Bolshesyrsky igneous area, a thick intraplate igneous complex of Khakassia, was carried out. The complex has not been dated due to the peculiarities of the stratigraphy and the lack of suitable rocks for applying the methods ...

A zircon case for super-wet arc magmas

Nature Communications
Arc magmas have higher water contents (2-6 wt.% H2O) than magmas generated in other tectonic environments, with a growing body of evidence suggesting that some deep arc magmas may be ‘super-wet’ (>6 wt.% H2O). Here, we use thermodynamic modelling to show
