des affleurements rocheux peu marqués 06:41 Jul 27, 2017
from what I could find so far, it would most literally mean that there are only few "marks" on these rocks - few visible cracks, or visible limits between layers, or visible faults ... a plain / bland surface;
OTOH " des affleurements rocheux peu marqués" could also mean that these visible rocks are not a very noticeable "mark" on the surrounding landscape - relatively small in size, not very prominent erc.
You really need to know the subject matter to decide which one makes more sense - is it more likely to find a thin layer of herbs (= "une pelouse") on barren rocks if they are more or less "unmarked" or if the rocks are a "minor mark" on the landscape? |
