In general, sedimentary rock crystals would be crystals that are found in sedimentary rocks. Normally they are calcite or quartz as they are the minerals most likely to cement sediments to form sedimentary rocks. There is a group of sedimentary rocks called evaporites that include crystals of salt, gypsum, sylvite, glauberite, thenardite, mirabilite and a few others. However, there is a tremendous variety of other minerals that can produce crystals in sedimentary rocks. Geodes from Indiana, Illinois, and Kentucky can have crystals of barite, millerite, sphalerite, galena, fluorite, and aragonite. In other areas of the planet crystals of azurite and malachite can be found in sedimentary rocks. There are many, many other types of crystals that have been found in sedimentary rocks.
Well, Conglomerate is a sedimentary rock and sedimentary rocks are not crystalline in nature, but they do consist of mineral crystals such as Quartz.
Clastic sedimentary rocks. Clastic sedimentary rocks are formed when small sediment particles are compacted and cemented together. This happens when the sediments are glued together by tiny crystals or chemicals from fluids that have precipitated in the pores between the sediments.
they have more crystals
No. Those are igneous rocks. Sedimentary rocks from from the acummulation and lithification of weathered material.
This thing is a sh
Crystalline
Sedimentary rocks tend to have layers. Igneous rocks tend to have crystals. If you don't see layers or crystals, the rock might be metamorphic.
Chemical
Sedimentary rocks.
A sugar cube looks like a sedimentary rock because, it has small and tiny particals such as those tiny crystals you see in a sugar cube. A sedimentary rock on the other hand, is composed of small sediments, like a sugar cube is composed of small particals and crystals.
Detrital sedimentary layers.
