I've no idea, this is just how I conceive of it to make it work for maps. It doesn't' have to be realistic (which TBH is hard to achieve without a complete understanding of the current science, science which doesn't have a complete understanding either), it just has to look good. Indeed I'm a bigger fan of drawing something that looks good, then doing my fake tectonics then editing the map to conform better to those tectonics, then back and forth until it feels right. So... very little science involved when I personally go about this method
