Basic Examples (5)
The default plate configuration is for the Holocene epoch:
Query for available plate configurations during a specified geological period:
Some geological periods have more than one set of configurations available:
Request the continental plates of the geological period corresponding to a specified time in the past:
A single result may be returned if the provided value exactly matches one of the available time keys:
Scope (2)
The available dates for a given geological period can be requested:
Some geological periods have no available data:
ContinentalPlateMaps can be applied to any of the following geological periods:
Options (6)
ContinentStyle (1)
Continent colors can be specified using any valid graphics directive:
GeoBackground (1)
Set the background to white:
GeoCenter (1)
Change the center:
GeoGridLines (1)
Do not show the grid lines:
GeoProjection (1)
Use an orthographic projection:
Outlines (1)
Continental plate outlines are set to None by default but can be specified:
Applications (4)
Visualize the continental configuration when the supercontinent Rodinia existed:
Visualize the continental configuration when the supercontinent Pangaea existed:
Visualize the position of India as it was moving northward during the Cenozoic era:
The Appalachian Mountains began to form when volcanic island arcs collided with Laurentia (core of modern North America):
Properties and Relations (2)
Because the result of ContinentalPlateMaps is an Association, the value for any key‐value pair can be obtained by supplying the key of interest:
Request the continental plates for a specific date instance:
Possible Issues (2)
Not all geological periods have data available:
Geological time periods are organized hierarchically with eons being the longest span, then becoming shorter through eras, periods, and epochs. As a result, when requesting the continental plate configuration for a time quantity, the result corresponds to the shortest geological period that contains the specified quantity. Epochs are preferred over periods and longer time intervals:
This corresponds to the same result as for the Holocene epoch as opposed to the Quaternary period, the Cenozoic era or the Phanerozoic eon, all of which contain the 12,000-years-ago specification:
Neat Examples (2)
To create an animation, first get a list of geological time entities:
Because geological time periods are hierarchical and some are missing data in the most ancient cases, some cleaning, merging and sorting is needed to get a flat list of frames:
