Conglomerate (/ k ə n ˈ ɡ l ɒ m ər ɪ t /) is a coarse-grained clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts, e.g., granules, pebbles, cobbles, and boulders, larger than 2 mm (0.079 in) in diameter.Conglomerates form by the consolidation and lithification of gravel. Conglomerates typically contain finer grained sediment, e ...

Sedimentary rock - Wikipedia

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment ...

angular shaped grains are interlocking, and this is how grains in granite or gabbro are held together (see Figure 2). These features are important tools in classify- ing rocks and assigning them to one of the three major rock groups. As will be discussed following, sedimen-tary rocks are made up of fragments of pre-existing (2A) (2B) Figure 2. Rock held together by (A) cemented and (B ...

The composition is determined by the mineral material and rock that the angular fragments were produced from. The composition of breccia can be influenced by the climate. The type of rock that the fragments were produced from is often used as an adjective in the name of the rock.

Feb 24, 2018 - A Breccia is a coarse, clastic, sedimentary rock, the constituent clasts (> 2 mm) of which are angular. The spaces between the large angular fragments can be filled with a matrix of smaller particles or a mineral cement that binds the rock together. 'Breccia' literally means 'rubble'.

Breccia Facts

Traduire cette page

Breccia is a clastic sedimentary rock composed of angular fragments of older rocks joined together by smaller particles or bonded by mineral cement. The fragments are usually around two millimeters or larger. It forms where angular, broken fragments of mineral or rock debris accumulate. The angular shape of the particles indicates minimal transport.

Unconformity Types, Disconformity, .

An angular unconformity is the contact that separates a younger, gently dipping rock unit from older underlying rocks that are tilted or deformed layered rock. The contact is more obvious than a disconformity because the rock units are not parallel and at first appear cross‐cutting. Angular unconformities generally represent a longer time hiatus than do disconformities because the .
