Sandstone caves are found in the sedimentary rocks composed of aggregates of sand grains. The sandstone was originally deposited as sandy sediments in rivers, beaches or shallow marine environments. Continued deposition of sediments caused the sediments to be buried deeply and transformed into sandstones. Quartzites are sandstones metamorphosed by heat or pressure and with stronger cements. A cave may form after the sandstone or quartzite is uplifted and exposed at the surface. Sandstone caves may be formed by rain or wind erosion, but more commonly when a stream is able to pass through joints or bedding planes in the rock. The weaker silica cement is slowly dissolved and the stream washes the loosened sand grains away. The finest examples are found in quartzite, especially in South America.

Sandstone caves are scarcely formed in the case that water can go through flat surface of rocks.

Sandstones can be transformed into quartzites by exterior conditions.

Sandstones caves can be created where sandy sediments are accumulated to be sandstones.

When cement becomes disintegrated, it gets swept away by the stream.
