Explanation / Answer

Calcareous balls= Oolites(these are rounded structures formed by rolling over calcareous mud)

Glacial debris gets compacted to form a rock called Tillite. These are generally composed of angular fragments derived from the glaciers.

So, Glacial Debris=Tillite

Coquina is a compacted sedimentary rock almost entirely composed of fragmented or entire remains of living organisms.Shell Hash is the vast accumulation of fragmented shell material.

So, Shell Hash=Coquina

Boundstones are in situ limestones in which the binding mechanism of organic debris is unknown.So, it can be formed at the Coral heads.

So, Coral heads=Boundstones

Swamp debris, after their transformation through long period of time, converts into Coal.

So, Swamp debris= Coal

Very fine clastic debris=Shale(its a fine grained rock formed from mud)

Alluvial fans are characterized by the sudden change in the slope of the river. At these places all the materials transported by the river get deposited. This process forms Conglomerate.

So, Alluvial fans=Conglomerate

Arenites are rocks composed almost entirely of quartz.

So, Mostly quartz=Arenite

Wacke are rocks that have a considerable amount of mud present in the matrix.

So, Carbonate Mud=Wacke

Sand and mud fractions= micrite
