Breccia grain size is influenced by several factors. First, the nature of the source material from which the rock fragments are derived plays a critical role. If the source material is fine-grained, such as shale or siltstone, the resulting breccia may have a finer grain size. Conversely, if the source material is composed of coarser-grained ...
