Out of context as it is, I would say it is genitive absolute.
What I mean is that we do not know the rest of the sentence, so there is no context to take into account. So I supposed that you extracted a part of a sentence, and that this "phrase" had "no grammatical relationship to the rest of the sentence" to quote Athenaze, and that it is therefore a genitive absolute. .
But I might be wrong...sorry if I confused you
and even if the first genitive wasn't a part of the prep. phrase, it is not uncommon to use
as many possessive genitives as needed.
