Tree identification

David, if it's any help with identifying the leafmines, the plant they are on looks to be Quercus ilex (Holm Oak) not Sorbus aria.

Blotches

I agree with Steve that the leaves look like those of an evergreen oak. Whether Quercus or Sorbus, the ring shaped blotches are not caused by Coleophora larval feeding. Similar observations have appeared on the Yahoo leafmines site with no precise conclusion as to their cause, although it seems to be fungal.
