Here's a breakdown:

* Clastic means the rock is made up of fragments (clasts) of other rocks.

* These fragments are cemented together by a mineral called a cement. Common cements include calcite, quartz, and iron oxides.

Some examples of clastic sedimentary rocks include:

* Conglomerate: Rounded fragments of rocks cemented together.

* Breccia: Angular fragments of rocks cemented together.

* Sandstone: Sand-sized grains cemented together.

* Shale: Very fine-grained, clay-sized particles cemented together.
