[1] We report on seismic and petrological data that provide new constraints on the geological evolution of the Amerasia Basin. A seismic reflection transect across the Makarov Basin, located between the Mendeleev and Lomonosov Ridges, shows a complete undisturbed sedimentary section of Mesozoic/Cenozoic age. In contrast to the Mendeleev Ridge, the margin of the Lomonosov Ridge is wide and shows...

Unconfined compressive strength (UCS) is an important rock parameter required in the engineering design of structures built on top or within interior formations. In a site investigation project, UCS typically obtained discretely (through point-to-point measurement) and interpolated. This method less than optimal to resolve meter-scale variations heterogenous such as carbonate formations which p...
