Breccia ( /ˈbrɛtʃiə/ or /ˈbrɛʃiə/; Italian: breach) is a rock composed of broken fragments of minerals or rock cemented together by a fine-grained matrix, that can be either similar to or different from the composition of the fragments.

The word is a loan from Italian, and in that language indicates either loose gravel or stone made by cemented gravel. A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, tectonic breccia, igneous breccia, impact breccia and hydrothermal breccia.

Sedimentary breccias are a type of clastic sedimentary rock which are composed of angular to subangular, randomly oriented clasts of other sedimentary rocks. They are formed by either submarine debris flows, avalanches, mud flow or mass flow in an aqueous medium. Technically, turbidites are a form of debris flow deposit and are a fine-grained peripheral deposit to a sedimentary breccia flow.

The other derivation of sedimentary breccia is as angular, poorly sorted, immature fragments of rocks in a finer grained groundmass which are produced by mass wasting. These are, in essence, lithified colluvium. Thick sequences of sedimentary (colluvial) breccias are generally formed next to fault scarps in grabens.

Alberto Breccia (April 15, 1919 - November 10, 1993) was an Uruguay-born Argentine comics artist and writer.

Born in Montevideo, Uruguay, Breccia moved with his parents to Buenos Aires, Argentina when he was three years old. After leaving school, Breccia worked in a tripe packing plant and in 1938 he got a job for the magazine El Resero, where he wrote articles and drew the covers.

He began to work professionally in 1939, when he joined the publishing house Manuel Láinez. He worked on magazines such as Tit-Bits, Rataplán and El Gorrión where he created comic strips such as Mariquita Terremoto, Kid Río Grande, El Vengador (based on a popular novel), and other adaptations.

During the 1950s he became an "honorary" member of the "Group of Venice" that consisted of expatriate Italian artists such as Hugo Pratt, Ido Pavone, Horacio Lalia, Faustinelli and Ongaro. Other honorary members were Francisco Solano López, Carlo Cruz and Arturo Perez del Castillo. With Hugo Pratt, he started the Pan-American School of Art in Buenos Aires. In 1957 he joined publisher Editorial Frontera, under the direction of Héctor Germán Oesterheld, where he created several Ernie Pike stories. In 1958 Breccia's series Sherlock Time ran in the comic magazine Hora Cero Extra, with scripts by Oesterheld.

Amedeo Minghi (born in Rome, Italy on 12 August 1947) is an Italian singer/songwriter. He has written songs for Andrea Bocelli, Mietta, Mia Martini, Anna Oxa, Marcella Bella, Gianni Morandi and Rossana Casale and composed several sound tracks as for the television film Fantaghirò (aka Cave of the Golden Rose).

Enrique Breccia (born 1945 in Buenos Aires) is an Argentine comic book artist.

Enrique Breccia, the son of one of the greatest Latino-American artists of all time, Alberto Breccia, drew his first work in 1968, when together with his father he illustrated La Vida del Che, a biography of the famous revolutionary Che Guevara written by Héctor Germán Oesterheld. In 1972 he started his collaboration with the British publishing house Fleetway, drawing the comic book Spy 13 under a pseudonym, and later a series of war stories for the Italian magazine Linus.

His collaboration with writer Carlos Trillo began in 1976 with the comic El Buen Dios, immediately followed by Alvar Mayor, his most famous character with whom he entered the world comic book scene. He had several other successful collaborations with Trillo, the mini series El peregrino de la Estrellas, the surreal series Los Viajes del Marco Mono and the painted El Reino del Azul. In 1983 he drew Ibáñez from the script of Robin Wood, and the next year the highly successful El Sueñero and El Cazador del Tiempo from his own scripts. He also drew several comic book adaptions of famous novels such as Till Eulenspiegel, Treasure Island and Moby Dick. In 1987 he published the graphic novel Lope de Aguirre and in 1995 De Mar a Mar.
