Answer 1

I would go for chemical sedimentary, as it is rich in minerals like feldspar and mica, which dissolve to clay.
It would not be classic or foliated as they are more for physical weathering , which occurs at low temperatures, and such condition does not favour chemical reaction.
organic sedimentary is out of the question as organic material is poor in minerals.
