DOI: 10.1016/j.jvolgeores.2020.107033
Abstract: Abstract Magma is transported through the lithosphere as dykes which, during periods of unrest, may feed eruptions at the surface. The propagation path of dykes is influenced by the crustal stress field and can be… read more here.

DOI: 10.1016/j.lithos.2019.03.015
Abstract: Abstract The NNW trending tholeiitic Sonakhan mafic dyke swarm of the Northern Bastar Craton is comprised of basalt to basaltic andesite (SiO2 = 46.3 wt% to 55.3 wt%; Mg# = 37 to 70) dykes. A single basaltic dyke yielded a weighted-mean… read more here.

DOI: 10.1016/j.precamres.2020.105773
Abstract: Abstract The geodynamic origin of the 1.78 Ga dyke swarm in the North China Craton (NCC) is long debated. It is considered either a post-collision process or paleoplume-related. Constraining its origin is essential for the reconstruction… read more here.
