I believe the pseudomorph of limonite after pyrite from Farafra Oasis, White Desert, Egypt that you posted is actually limonite replacing marcasite.

Actually I think it is pseudo after real Pyrite. You can easily distinguish Marcasite by its original shape.
Pyrite has an interesting growing pattern called Triaxial cube.
Triaxial cubic Pyrite is not a twinned crystal, but is due to inhibited growth at the edge of the cube. Cube crystal growths only on the faces and not on the edges. Is the same process of Trapiche Emeralds formation.
