Does anyone have a geological map 1 / 1 000 000 or 1 / 50k of Morocco in HD?
It is not so evident if you look for the big picture (grammar school's project?), or detail and specific region.  Because even today, the geological mapping of Morocco is not complete (gouvernmental reference), the 19 already digitized geological maps about Morocco  on gallica.fr may be an interesting entry for you.  The GUI interface is more helpful for books, than for maps (selection of the page, export as .pdf / .jpeg), but there is a zoom and pan option to see some details on the maps pretty well.
E.g., a more general one by Brumnich (1936, 1:500'000) here, or one with stratigraphic / petrographic details about central Morocco by Termier (1932, 1:200'000) here.
