    Diagenesis - Wikipedia

    https://en.wikipedia.org/wiki/Diagenesis

    Diagenesis is the process that describes physical and chemical changes in sediments first caused by water-rock interactions, microbial activity, and compaction after their deposition. Increased pressure and temperature only start to play a role as sediments become buried much

    https://es.wikipedia.org/wiki/Diagénesis

    La diagénesis (griego, δια- día-, «a través de», y γένεσις génesis, «origen») ​ es el conjunto de procesos de formación de una roca sedimentaria a partir de sedimentos, tales como compactación, recristalización o cementación. La diagénesis se produce en el interior de los primeros 5 o 6 km de la corteza terrestre a temperaturas inferiores a 150-200 °C; más allá se considera ya metamorfismo. ​

    Diagenesis adalah perubahan dari sedimen atau batuan sedimen yang ada menjadi batuan sedimen yang berbeda selama dan setelah terbentuknya batuan (litifikasi), pada suhu dan tekanan kurang dari yang dibutuhkan untuk pembentukan batuan metamorf. Diagenesis tidak termasuk perubahan dari pelapukan. Diagenesis adalah segala perubahan kimia, fisika, atau …

      https://wiki.seg.org/wiki/Diagenesis

      Diagenesis is the change of sediments or existing sedimentary rocks into a different sedimentary rock, mineral, or texture. It can occur during or after rock formation (lithification) at temperatures and pressures less than less than those for metamorphic rocks. Diagenetic conditions can occur at the surface or underground up to a few km.

      Da Wikipedia, l'enciclopedia libera. In geologia la diagenesi è un qualsiasi cambiamento chimico-fisico subito da un sedimento dopo la sua deposizione iniziale, durante e dopo la sua trasformazione in roccia coerente, ad esclusione dell'alterazione superficiale ( erosione ), I cambiamenti diagenetici avvengono a temperature (fino a circa 200 ...

      • Diagenese im Sinne der Umwandlung eines Lockersedimentes in ein Festgestein umfasst im Wesentlichen zwei Prozesse: Kompaktion und Zementation.Frühdiagenetische Prozesse beinhalten ausschließlich Zementation und laufen bereits kurz nach der Ablagerung ab. Bei der Zementation bilden sich im Porenraum des Sedimentes Kristalle durch Abscheidung von Salzen …

      • Litificação (lithus em grego clássico: λίθος que significa rocha e do sufixo-ific do latim) é o processo em que os sedimentos compactados sob pressão, expulsam os fluidos e gradualmente se tornam rocha sólida. Essencialmente, litificação é um processo de destruição da porosidade por meio de compactação e cimentação. Litificação inclui todos os processos qu…
