#SOFTCAM KEY NORTH AMERICA SERIES#

All map elements, both internal to North America and fringing or exotic, are palinspastically restored to each given time slice using recent data from literature.

Cloned modern Earth DEM images from GeoMapApp are selected as modern analogues to the paleo-features they are chosen to represent most DEM images have been re-colored, resized, and/or re-shaped in PhotoshopВ®.

Paleogeography is cloned or painted using PhotoshopВ® cloned images are mostly from GeoMapApp, a marine geoscience, global topography data system ( ).

This information is then used to construct the paleogeography

Paleogeographic and paleotectonic elements (thrust belts, volcanic centers, paleo-shorelines, dune fields, basin geometry, facies maps, etc.) are plotted from the geologic literature and redrawn, repositioned, or reprojected on the base maps for the given time slices.

Maps are rasterized pixel images, not shape files (nor are they based on shape files).

The attached reference list includes all the references used in making all of the maps in the two North American series (SW North America Key time slices). By not deforming state lines, the paleogeography shows more clearly and without confusing lines. Terrane-block motion is shown (restored) relative to the interior stable craton of North America.

Note that state lines are not deformed, a common method of showing palinspastic restorations in many publication rather state-county lines are minimized until the time slice at which the terrane arrives at its present location for a given area. apart.ДЄll of the features on the maps are palinspastically restored - that is, the positions of various terranes and blocks are shown in their presumed location during a given time slice. between maps and only two time slices are more than 20 m.

The 36 time slices mark a reduction from the 90+ maps in the original North American series but this strategy was considered to be a necessity of time as most maps in the new series took 40 вЂ“ 60 hours each to complete. Particular attention was paid to making sure that tectonic and geologic events between adjacent time slices made geologic, geographic (space issues), and tectonic sense. The maps were compiled from many sources (see references) and are based on many different tectonic models numerous compromises between varying models were necessary, especially models of terrane accretion. Their detail and image size make them some of my most detailed maps. The maps represent a complete redo of the previous North American series map size and resolution were increased by nearly twice and new data from the geologic literature were used in map preparation. The Key-Time-slice series of paleogeographic maps for North America was completed in June, 2013.
