PLATE 1 Physiography, tectonic plates and ocean lineations
MAP 1. Ocean and continental physiography, crustal plate boundaries, and magnetic isochrons in the
Central Atlantic region, Google Earth rendtion to the right.


PLATE 2 Color physiography, plate boundaries and ocean lineations
MAP 2. Ocean and coninental colored physiography, crustal plate boundaires, crustal seismic
zones, crustal-plate horozontal velocity vectors based on GPS readings over the past 12 years,
and North American continetal rivers . Physiographic base isUSGS TIFF image.

MAP 3. Continental polygons, tectonic plate boundaries, rivers and lakes (ESRI),  line traces of
ocean-floor lineaments,  crustal faults (USGS), GPS horizontal component of crustal plate motion
( NASA-JPL), crustal seismic zones and impact  architecture showing 660, 1700, and 2900 km rings
representing crests and troughs of crustal welts.. Pricipal axis of compression extends foreland  of
the impact craters in line with bolide oblique-impact trajectories.

PLATE 6. Equipotenbtial surface of vertical crustal motion
MAP 6. GPS vertical crustal motion represented with TIN surface of equipotential vertical velocity  
(NASA-JPL) with other map data from MAP 1-3. Continental regions of uplift (U) and susidence (S)
reflect overlapping and interfering ring structures stemming from the Chicxulub (~65mya) and 
Chesapeake (~35mya) impacts. l
