Iron Oxide Cemented With Sandstone

Mud-free frag- ments of fossil wood are also surrounded by cylindrical rinds of iron oxide that cement grain-supported sandstone, and iron oxide ce- ments fill the void space within some thick, tabular masses of channel sandstone. Thin sections of channel sandstones reveal that this iron oxide forms rhombic, poikilotopic pseud- omorphs (Fig. 3G).

Everything You Need to Know About Sandstone

2019-8-14  Sandstone, simply put, is sand cemented together into rock — this is easy to tell just by looking closely at a specimen. But beyond that simple definition lies an interesting makeup of sediment, matrix, and cement that can (with investigation) reveal a great deal of valuable geologic information.
