The crystal size of the minerals that make up sedimentary rock will vary, dependent mostly on the distance the sediments traveled and the amount of weathering they experienced before deposition. The sedimentary rock shale, for instance, is composed of clay and quartz particles which are not visible to the naked eye, and are the product of chemical and mechanical weathering processes over long expanses of time. Quartz sandstone grains, however, are visible to the naked eye, and represent a slightly less rigorous exposure to weathering processes. There are several different methods of sedimentary rock formation which also influence the grain size in sedimentary rocks. Please see the related question below.

What are sedimentary rock crystals?
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.
Does conglomerate have any crystals?
Well, Conglomerate is a sedimentary rock and sedimentary rocks are not crystalline in nature, but they do consist of mineral crystals such as Quartz.
Sedimentary rocks composed of intergrown precipitated crystals are called?
Crystalline
What type of sedimentary rocks forms when crystals grow out of solution?
Chemical
Is a sedimentary rock made of crystals?
Sedimentary rock is composed of minerals. The minerals may be in the form of particles of other rocks that are made of minerals themselves, as well as the minerals of the cementing material that holds those particles together. In certain cases, the minerals have formed as a result of the evaporation of or precipitation from saturated solutions containing the components of minerals. Sedimentary rocks can contain visible crystals as well as crystals that are not visible without the aid of magnification.

Do sedimentary rocks have tiny crystals?
yes
Does conglomerate have any crystals?
Well, Conglomerate is a sedimentary rock and sedimentary rocks are not crystalline in nature, but they do consist of mineral crystals such as Quartz.
Why do sedimentary and metamorphic rocks have bands of colors?
they have more crystals
Do sedimentary rock form from crystals solidifying from magma?
No. Those are igneous rocks. Sedimentary rocks from from the acummulation and lithification of weathered material.
What type of sedimentary rocks for when crystals grow out of solution?
This thing is a sh
Sedimentary rocks composed of intergrown precipitated crystals are called?
Crystalline
How would you know the difference between igneous and sedimentary and metamorphic rock?
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.
What type of sedimentary rocks forms when crystals grow out of solution?
Chemical
What are a couple of examples of sedimentary rocks?
Rocks that are categorized as sedimentary rocks include sandstone, breccia shale, limestone and selenite. Sedimentary rocks are classified by their grain size.

Which type of rock typically has the largest formed crystals?
Igneous rocks usually contain the most crystals. The longer it takes the magma to cool, the larger the crystals. According to the Earth Science Reference Tables, pegmatite contains the largest crystals.
