Exterior's sheer silica-rich pumice mud from Havre Submarine eruption of 2012 is in contrast with front's two samples. Chatter pattern is glazed with earth crust slurry from Mid-Atlantic Ridge at Kane Fracture Zone. Fine grained brown sediment between word band and rim is from an area described to me as the Costs Rican accretionary prism.
