Salt Range Formation of Pakistan Preserves Unique Record of Volcanic Fertilization During the Ediacaran Shuram Excursion

Terra Nova, EarlyView.
ABSTRACT Thin, discontinuous, organic‐rich oil shale beds in the siliciclastic‐evaporitic Salt Range Formation (SRF) of Pakistan are of approximate Neoproterozoic to Cambrian age based on stratigraphic constraints. The beds are enriched (26–43 wt.% total organic carbon, TOC) in aliphatic organic matter (OM) of low thermal maturity despite their ...

U–Pb Dating of Cambrian Magmatism in the Pinerolo‐Sanfront Unit, Dora‐Maira Massif (Western Alps)

Terra Nova, EarlyView.
ABSTRACT The Pinerolo‐Sanfront Unit (PSU), the structurally lowest tectonic unit of the Dora‐Maira Massif (Western Alps), has been regarded as a monocyclic unit composed of Permo‐Carboniferous sediments and Permian granitoids that were metamorphosed during the Alpine orogeny.

Origin of the King's Trough Complex (North Atlantic): Interplay Between a Transient Plate Boundary and the Early Azores Mantle Plume

Geochemistry, Geophysics, Geosystems
The King's Trough cuts into an area of thickened oceanic crust associated with the 45°N melting anomaly at the Mid‐Atlantic Ridge. Here we present a comprehensive geochemical data set and new 40Ar/39Ar age and bathymetric data from magmatic rocks from ...
