diyajenez (sediment veya sedimanter kayaçların çökelmeden sonra maruz kaldıkları değişimler olup metamorfizma olarak adlandırılan yüksek sıcaklık ve basınç değişimlerini kapsamaz)
English - English
Definition of diagenesis in English English dictionary
All the chemical, physical, and biological changes sediment goes through during and after lithification, not including weathering or other surface changes
Sum of all processes, chiefly chemical, that produce changes in a sediment after its deposition but before its final lithification. Usually, not all the minerals in a sediment are in chemical equilibrium, so changes in interstitial water composition or in temperature or in both will lead to chemical alteration of one or more of the minerals present. Diagenesis is considered a relatively low-pressure, low-temperature alteration process that involves such processes as cementation, reworking, replacement, crystallization, and leaching
The set of processes that cause physical and chemical changes in sediment after it has been deposited and buried under another layer of sediment Diagenesis may culminate in lithification
All the physical, chemical, and biologic changes undergone by sediments from the time of their initial deposition, through their conversion to solid rock, and subsequently to the brink of metamorphism
All chemical, physical, and biological modifications undergone by a sediment after its initial deposition
Post-depositional modification to a sediment Typically involves compaction, cementation and induration (qv)
The chemical and physical changes occurring in sediments before consolidation or while in the environment of deposition
Processes involving physical and chemical changes in a sediment after deposition that convert it to a rock The processes include compaction, squeezing out of excess water, cementation, and sometimes recrystallisation (especially in limestones) These are processes brought about by water percolating through the sediment and by the low pressures of new sediment being deposited on top Diagenesis is the process of turning sediment into rock, as distinct from metamorphism which involves much higher temperatures and/or pressures and changes one rock to another
All of the changes that occur to a fossil (or more generally any sediment) after initial burial; includes changes that result from chemical, physical as well as biological processes The study of diagenesis is part of taphonomy
