Rocks are generally subjected to weathering, not formed directly by weathering.


For example, a granite that is chemically or mechanically weathered will break down into the minerals quartz and feldspar which are then transported in streams (erosion) to the ocean and dumped in. After millions of years of sediment buildup in the oceans, these quartz and feldspars will turn into the sedimentary rock, Sandstone.
