HELP! What minerals are in conglomerate rocks?

Question

Other than quartz
I CAN NOT FIND ANYTHING ON CONGLOMERATES

Answer 1

A conglomerate is a sedimentary rock composed of rounded clasts (angular clasts will make a breccia) that are mostly larger than sand size, that is greater than 2 mm in diameter.

As with many sedimentary rocks, there is no particular mineral that makes up the rock. Conglomerates can be made from other rocks, such as clasts of conglomerate, clasts of sandstone, clasts of shale, clasts of metamorphic rock, clasts of igneous rock, or clasts of carbonate rocks like limestone.

The minerals present in the conglomerate depend on what is known as the provenance, or the source rock that the individual grains within the conglomerate are made of. Because of this a conglomerate could contain almost any mineral. This is probably why you can't find anything on this.

Typically, a conglomerate is going to be made from rock that has survived enough weathering by streams or water (to make the clasts round). Quartz is likely to be a high proportion, but this is not always true. Most often the clasts are not single minerals, but are rocks with many minerals. Almost anything is possible.

Answer 2

Conglomerate Rock

Answer 3

A conglomerate is a rock that is made up of smooth rounded pieces of many other rock types ...not just minerals per se .... the smooth pebbles and cobbles are cemented together by finer grains and the minerals present would be dictated by the different rock types found in the conglomerate .....if the rocks fragments are not smooth but rough and sharp edged the rock is called a breccia .... both types of rocks are usually found in old river or beach deposits .... the conglomerate has traveled the farthest before it was buried by another layer that is why the pebbles and cobbles are all smooth and sort of rounded.

Conglomerate is a rock that has pieces of other rocks glued together to form one larger chunk. It is a sedimentary rock that can be found along beaches, rivers, and glaciers where water or ice drops them off. It is made up of pebbles and other small rocks that are a quarter of an inch around or bigger. The pebbles can be made of quartz, or some other mineral. It is glued together with iron oxide, calcium carbonate, or silica. It looks lumpy with bigger rocks cemented with small gravel and sand. If you look at the two conglomerate rocks on the right, you will see that they look very different. They look so different because they were formed in different places and were made up of different kinds of small rocks, sand, and minerals.

Answer 6

Conglomerate rocks are sedimentary rocks. They are made up of large sediments like sand and pebbles. The sediment is so large that pressure alone cannot hold the rock together; it is also cemented together with dissolved minerals. The pebbles can be made of quartz, or some other mineral. It is glued together with iron oxide, calcium carbonate, or silica. It looks lumpy with bigger rocks cemented with small gravel and sand.

Answer 7

Conglomerate rocks, by definition, have any combination of minerals in them. The word "conglomerate" means "made up of many things".

Answer 8

It would depend upon the composition of the clasts and the matrix.
Clasts could be of quartzite, granitoid, basic rocks, carbonates (limestone/dolomite & marble). The composition of a conglomerate rock would depend upon the provenance.
Some conglomerate are dimondiferous & auriferous also.
