The conglomerate

In the early stages of its formation, the conglomerate is a sediment composed of gravel and fragments off the coral.

Next, the fine sand and clay will fill the space between the fragments, then another process that filters down the particles to fill the interstitial space.

The precipitation of chemical cement then binds the sediment into intact rock, which is finally referred to as a conglomerate.

But the most decisive factor in the formation of a conglomerate is the power of water. It takes strong water to transport fragmented particles. Therefore, it will only exist in the flow of a stream that is fast-flowing or on the coast of the sea with large waves.

So, I think, it needs a very large thrust so that one particle is tied up with another ... to unite and make a unity ...

And one more thing ...

The round shape of the fragment indicates that there is a process of deforming the fragment (sorting) by the speed of the flow of water during the transport process takes place.

What I think about this .... for a change, speed is something that is absolutely necessary.

Some other pictures I found where I saw the conglomerate process formed.
