--- Comment #12 from Constantine sullome@yandex.com --- After playing through an entire game I can say that this dark surfaces mostly appear at the entrance of caves. Other times, this surfaces continue the "default" landscape. For example, if there is a hill and an area is a... pit or something like that, something that "penetrate" the default terrain will be covered with this surfaces.
Also, after fixing the black ground bug, this surfaces are not black anymore. So I think that this surfaces are actually the default terrain that, for some reason, was not hidden.
