Thank you all for the welcome
@ Neonknight & RPMiller: I apologize for not taking the time to explain but I was a bit pressed for it at the moment I wrote the first post. To quote myself from elsewhere:
Gondolend
TlaquanaruThe legend is as follows:
Black thin lines = continental outline
Blue thin lines = rivers and lakes
Dark red thin lines = mountains
Magenta thin lines = (composite) fold axis
Red transparent areas = orogenies
Turquoise transparent areas = geologically stable areas; cratons
Blue thick lines = subduction trenches
Red thick lines = rifts
Yellow thick lines = plate collision[ area]s
Green thick lines = transform faults
I might as well show you one of my first if not the first serious map I made when I was 16-18 years old. It was for a fan fiction scenario where an expedition found a world where something very similar to the Alien Saga xenomorph evolvedI think the colours I used are more or less straight forward, though it best be told that the thin orange lines denote high country, 1000+ m altitude, whilst the dark red ones denote the 3000+ m limit [and the thin turquoise ones denote the continental shelf]. The thick green lines are transform faults and the bright magenta ones are collisional boundaries.
The signage is as follows:
Double lines - rifts
Lines with triangles - subduction trenches, triangles on the overthrust side.
Simple lines - transform faults
Thick lines - collisional plate boundaries
