Quizplus · Accepted Answer

The presence of small rounded pebbles suggests that the sandstone was formed by the process of sediment transport, likely by a river. The fact that it was deposited far from the ocean further supports this interpretation, as rivers are a common source of sediment in continental environments. Sand dunes would not likely contain small rounded pebbles, and beaches next to a sea would not have formed without the presence of the ocean, which is not the case here. Deep-water turbidity currents are also not likely to have produced this type of sandstone.
