Kenai Group is a name given by Dall and Harris (1892) [1] to sedimentary rocks in the Cook Inlet Basin, Alaska. These rocks are instead called the Kenai Formation by several other authors. [ 2 ]
Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix. [5] Like conglomerate, breccia contains at least 30 percent of gravel-sized particles (particles over 2mm in size), but it is distinguished from conglomerate because the rock fragments have sharp edges that have not been worn down.

Pebble −1 to −2 2–4 mm 0.079–0.157 in Very fine gravel Granule: 0 to −1 1–2 mm 0.039–0.079 in Very coarse sand: 1 to 0 0.5–1 mm 0.020–0.039 in
Two recognized types of intraformational conglomerates are shale-pebble and flat-pebble conglomerates. [6] A shale-pebble conglomerate is a conglomerate that is composed largely of clasts of rounded mud chips and pebbles held together by clay minerals and created by erosion within environments such as within a river channel or along a lake ...
Close view of pebbles [vague]. A pebble is a clast of rock with a particle size of 4–64 mm (0.16–2.52 in) based on the Udden-Wentworth scale of sedimentology.Pebbles are generally considered larger than granules (2–4 mm (0.079–0.157 in) in diameter) and smaller than cobbles (64–256 mm (2.5–10.1 in) in diameter).
Bianca Censori opted for an interesting accessory while out in Miami.. Censori, 28, was photographed outside of a nightclub with husband Kanye West on Sunday, December 10, wearing a barely-there ...
A pebble-bed power plant combines a gas-cooled core [5] and a novel fuel packaging. [6]The uranium, thorium or plutonium nuclear fuels are in the form of a ceramic (usually oxides or carbides) contained within spherical pebbles a little smaller than the size of a tennis ball and made of pyrolytic graphite, which acts as the primary neutron moderator.
Gravel (largest fragment in this photo is about 40 mm (1.6 in)) Gravel (/ ˈ ɡ r æ v əl /) is a loose aggregation of rock fragments.Gravel occurs naturally on Earth as a result of sedimentary and erosive geological processes; it is also produced in large quantities commercially as crushed stone.
