Inconsistent correlation of seismic layer 2a and lava layer thickness in oceanic crust
Article Abstract:
Identical seismic experiments are conducted adjacent to the north walls of both the Hess Deep rift (HDR) and the Blanco transform fault (BTF) scarps in order to directly correlate the seismic layer 2A/2B boundary with mapped geologic units in young oceanic crust. The results have shown that the seismic layer 2A reflector corresponds to an alteration boundary that can be located either within the lava section or near the top of the sheeted dyke complex in oceanic crust.

The start of the world as we know it
Article Abstract:
The grand unified theory of geology, suggests that everything seen at present, from the abyssal plains of the oceans to the heights of the Himalayas, is plate tectonics, a process driven by Earth's heat and constrained by the physical and chemical properties of the crust and mantle. Geologists debate the origin of the plate tectonics process that seems to have shaped Earth.

Geochemical evidence from the Sudbury structure for crustal redistribution by large bolide impacts
Article Abstract:
The partial inversion of the compositional layering of the continental crust was caused by the hypervelocity impact. It is shown that using geochemical data, a mixture of the original surficial sedimentary strata, shock-melted lower crust and the impactor is represented in the matrix of the overlying clast-laden Onaping Formation using
