Could be conglomerate or breccia, depending on whether or not the clasts are rounded or angular.

What is the difference between various kinds of clastic sedimentary rocks?
The difference between types of clastic rocks lies in their clast size, composition, and depositional environment. Some clastic sedimentary rock may consist of boulder sized fragments, others of microscopic sized particles. Shales will consist of clay minerals--sandstones usually consist of quartz minerals. Shale is from shallow marine deposition--sandstone from near shore or windblown deposition.
What kind of rock is breccia?
Breccia is a clastic sedimentary rock composed of various sized visible pieces of other rock, cemented together by the processes of lithification.The pieces of rock that are visible are angular fragments, meaning they have somewhat jagged edges. This means that the fragments in the breccia did not travel far before they were deposited. If they had traveled longer and further they would have become rounded, in which case the resulting sedimentary rock would have been called conglomerate.
What kind of sedimentary rock is made of fragments of rocks cemented togeather by a mineral?
Clastic sedimentary rock. For a specific clastic rock....It depends on a lot of things. Grain size, sorting, roundness of clasts, and what mineral/how did it turn into cement are but a few. Best bet would be classifying based on grain size:Conglomerate - gravel sized clasts that are rounded. Matrix can range from lithic fragments to a cement of quartz to calcite to hematite etc...Breccia - as above, but clasts are angular.The above are the most likely to be described as containing "fragments of rocks", however for the below the statement is still valid--just not as obvious.Sandstone - smaller sand sized clasts whose cement may or may not be visible. Note that there are many different more specific names of sandstones based on mineralogy and percentage of matrix/cement.Mudstone/siltstone or Shale - silt/clay sized grains that are rarely visible without a hand lens.These are the most common, but there are certainly many, many more that could fit the description in your question. All of the above contain fragments of rocks, cemented by a mineral, just at different stages of weathering! Hopefully that helped!
What type of rock is sandstone?
Clastic sedimentary. Classification of rocks are based upon three types: geological process, ... or sedimentaryrocks (fragmental rocks) are sandstone, laterite, sand, ... Sandstone (sometimes known as arenite) is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz or feldspar because these are the most common minerals in the Earth's crust.
How is meta conglomerate different from conglomerate?
Conglomerate is a sedimentary rock that contains gravel-sized clasts. Metaconglomerate is conglomerate that has undergone metamorphism.

What is the particle size of clastic sedimentary rocks?
Shale is composed of the smallest particles of other rocks.
Is sandstone an igneous rock?
No. Sandstone is a sedimentary rock, composed of cemented grains of sand-sized sediment particles. Igneous rock is formed from the cooling of magma or lava.
What kind of rock is breccia?
Breccia is a clastic sedimentary rock composed of various sized visible pieces of other rock, cemented together by the processes of lithification.The pieces of rock that are visible are angular fragments, meaning they have somewhat jagged edges. This means that the fragments in the breccia did not travel far before they were deposited. If they had traveled longer and further they would have become rounded, in which case the resulting sedimentary rock would have been called conglomerate.
Is chalk and shale the same thing?
No. Chalk is a variant of limestone, composed primarily of calcite. It is a carbonate sedimentary rock. Shale is a laminated sedimentary rock composed of silt and clay sized particles of mostly silicate mainerals. It is a clastic sedimentary rock.
What are standstones made of?
Sandstones are made out of sand sized particles or rock grains. Sandstones are clastic sedimentary rock. Some sandstone is composed of feldspar or quartz.
What type of rock is red sandstone?
Redsandstone (sometimes known as arenite) is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains.
Rock that is formed by sand and mineral particles pressed together?
This will form a clastic sedimentary rock. If it is predominantly composed of sand sized grains then it will form a Sandstone.
What is the principal mineral in sandstone?
Sandstone is a type of clastic sedimentary rock with sand-sized minerals or sand grains. Its two chief minerals are quartz and feldspar.

What clastic rock is made of different sized rock fragment?
All clastic rocks are made up by rock fragments of different size. Siliciclastic rocks (rocks composed chiefly of broken up silicate material) are classified depending on what the predominant grain size is, how wide the spread in grain size is, what the form of the grains are and what the contributing minerals are. Very badly sorted clastic rocks with rounded fragments chiefly of gravel size is called conglomerate. Well sorted silicate material, mainly of sizes between 0.1 to 0.2 mm diameter, is called sandstone (made up of fine sand).
