3D Cartesian Rift

3D Cartesian Rift#

A simple setup of a rift in a Cartesian box, in which two plates are spreading at a constant spreading rate. The files can be found here.

The relevant part of the World Builder file looks like this:

 3  "features":
 4  [
 5    {"model":"oceanic plate", "name":"oceanic plate A", "coordinates":[[-1e3,-1e3],[2001e3,-1e3],[2001e3,1000e3],[-1e3,1000e3]],
 6     "temperature models":[{"model":"plate model", "max depth":95e3, "spreading velocity":0.005, "ridge coordinates":[[[1200e3,-1e3],[1200e3,1000e3]]]}],
 7     "composition models":[{"model":"uniform", "compositions":[0], "max depth":10e3},
 8                           {"model":"uniform", "compositions":[1], "min depth":10e3, "max depth":95e3}]},
10    {"model":"oceanic plate", "name":"oceanic plate B", "coordinates":[[-1e3,1000e3],[2001e3,1000e3],[2001e3,2001e3],[-1e3,2001e3]],
11     "temperature models":[{"model":"plate model", "max depth":95e3, "spreading velocity":0.005, "ridge coordinates":[[[800e3,1000e3],[800e3,1500e3]],[[1000e3,1500e3],[1000e3,2000e3]]]}],
12     "composition models":[{"model":"uniform", "compositions":[0], "max depth":10e3},
13                           {"model":"uniform", "compositions":[1], "min depth":10e3, "max depth":95e3}]}
15  ]

And the generated output model looks like this:
