What class of sedimentary rocks is made of fragment of rock minerals and shell?

A conglomerate.


What kind of sedimentary rock is made of fragments of rocks cemented together by minerals?

Conglomerate


Is conglomerate a clastic rock?

No, conglomerate is a sedimentary rock composed of rounded rock fragments cemented together. Clastic rocks are composed of individual grains or fragments of minerals or rocks that have been compacted and cemented together.


What type of sedimentary rock is from fragments of minerals or rocks?

Conglomerate or Breccia. You'd have to specify the shape of the fragments and types of minerals.


What are rock groups that are classified as clastic sedimentary rocks?

Some examples of clastic sedimentary rocks include sandstone, conglomerate, shale, and breccia. These rocks are formed from the accumulation of fragments of pre-existing rocks and minerals, which are then compacted and cemented together over time.


What causes crystalline layers through conglomerate rocks these layers cut through individual rocks?

The conglomerate must have been subjected to stresses sufficient to cause fracture in the individual rocks making up the conglomerate. The cracks were then infilled by minerals precipitating from fluids which were migrating through the rock.


Compare and contrast conglomerate and evaporite?

Conglomerate is a sedimentary rock composed of rounded gravel-sized particles, while evaporite is a sedimentary rock formed from the precipitation of minerals that were dissolved in water. Conglomerate forms from the erosion and transportation of pre-existing rocks, while evaporite forms through the evaporation of water. Both rocks can contain a variety of minerals and can provide clues about the environment in which they formed.


What is uranium present in?

Uranium is present in approx. 220 rocks and minerals.


What sedimentary rocks are made of fragments of rocks minerals and shells?

Sedimentary rocks made from fragments of rocks, minerals, and shells are known as clastic sedimentary rocks. Examples include sandstone, shale, and conglomerate. These rocks form when pre-existing rocks are weathered, eroded, transported, and deposited in layers.


Which minerals are not present in felsic type igneous rocks but are present in mafic type igneous rocks?

Mafic igneous rocks typically contain minerals like olivine, pyroxene, and amphibole which are not commonly found in felsic igneous rocks. These minerals have higher concentrations of iron and magnesium and form at higher temperatures as compared to the minerals present in felsic rocks.


Which element is present in the largest amount in rocks and minerals?

Oxygen is the element present in the largest amount in rocks and minerals. It is a major component of most minerals, forming the backbone of silicate minerals that make up the majority of the Earth's crust.


Where you can find conglomerate?

Conglomerate rocks are sedimentary rocks; they settle at bottoms of the rivers, lakes, and oceans in deposited layers.
