is sandstone a sedimentary rock that consists of minerals of quartz and feldspar, does it have any other minerals.

I believe it is formed by layers of sand accumulated resulting in sedimentation because the sandstone is formed when compacted under pressure. it is foliated and is hard coarse grains.
would love your ideas

Sandstone is largely quartz. It can contain a variety of other minerals including feldspar and mica.

Sandstones range from those that are poorly cemented and crumble in the hand, to those that are quite hard and used for building stone.
