New Late Cretaceous and CAMP Magmatic Sources off West Iberia, From High‐Resolution Magnetic Surveys on the Continental Shelf

open access: yesTectonics, Volume 42, Issue 7, July 2023., 2023
Abstract Magma‐poor rifted margins can be affected by magmatic occurrences coeval with rifting and post‐rifting. Understanding the geological processes that originated these magmatic events requires determining their extent, type and size of magmatic bodies and tectonics.

Saturation and geometrical scaling in small systems [PDF]

open access: yes, 2016
Saturation and geometrical scaling (GS) of gluon distributions are a consequence of the non-linear evolution equations of QCD. We argue that in pp GS holds for the inelastic cross-section rather than for the multiplicity distributions.
