Pyroclastics are rocks formed from the cooling and solidification of material ejected during explosive volcanic eruptions, and are so primarily igneous.
However, this material is often transported an redeposited by processes not directly related to volcanism. When this occurs, the resulting material may be considered sedimentary. Rocks that form from this transported volcanic material are called volcaniclastic rocks.

No, pyroclastic rocks are not considered sedimentary rocks. They are formed from volcanic activity where ash, cinders, and other volcanic fragments are compacted together. Sedimentary rocks are formed through the accumulation and cementation of sediments like sand, gravel, and mud.

Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
Is vein a sedimentary rock?
No, veins are not considered sedimentary rocks. Veins are mineral formations that fill fractures in rocks. Sedimentary rocks are formed through the accumulation and compaction of sediments, such as sand, silt, and clay.
Is hematite sedimentary?
Hematite can be found in sedimentary rocks as well as other types of rocks. However, the mineral itself is not considered sedimentary, as it forms primarily through hydrothermal or metamorphic processes.
Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No, sedimentary rocks formed from fragments of other rocks are called clastic sedimentary rocks. Chemical sedimentary rocks form from minerals that are dissolved in water and precipitate out to form rocks like limestone or halite.
Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.

Are some rocks metamorphic AND sedimentary?
No. If a sedimentary rock has undergone even a low grade metamorphism, it is considered a metamorphic rock.
Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No, sedimentary rocks formed from fragments of other rocks are called clastic sedimentary rocks. Chemical sedimentary rocks form from minerals that are dissolved in water and precipitate out to form rocks like limestone or halite.
Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
Are magma and rock both pyroclastic materials?
No. Magma is molten rock that is beneath earth's surface. When it erupts it can form lava or pyroclastic material. Although pyroclastic material can form rocks, most rocks are not from pyroclastic material.
Are volcanic rocks sedimentary?
No. Volcanic rocks are igneous (although not all igneous rocks are volcanic). Sedimentary rocks are made of sediment naturally cemented together. However, volcanic (or extrusive igneous) rocks can be eroded into sediment, which can be cemented, compacted, or otherwise become sedimentary rock such as sandstone or conglomerate. It is then not considered igneous.
Are basalt rocks pyroclastic?
Usually not. Although it is possible to have pyroclastic material with a basaltic composition, most basaltic rocks are from simple lava flows.
What are three types of rocks?
igneous, sedimentary, metamorphic
What type of rocks can contain fossils on them?
Sedimentary rocks. and metamorphic rocks made form sedimentary rocks.
