成岩作用, 成岩过程
the physical and chemical changes occurring in sediments between their deposition and their consolidation into sedimentary rock
- Diagenesis refers to the physical, chemical, and biological changes that sediments undergo after deposition and before lithification.
成岩作用指的是沉积物在沉积后和岩化前所经历的物理、化学和生物变化。
- During diagenesis, sediments may experience compaction, cementation, mineral alteration, and the migration of fluids, which ultimately lead to the formation of sedimentary rocks.
在成岩作用期间，沉积物可能会经历压实、胶结、矿物变化和流体迁移，最终导致沉积岩的形成。
- The process of diagenesis can transform loose sediment into solid rock, such as sandstone, shale, or limestone, over geological time scales.
成岩作用的过程可以在地质时间尺度上将松散的沉积物转变为固体岩石，如砂岩、页岩或石灰岩。
- Diagenetic processes often occur in the shallow subsurface, within a few kilometers of the Earth's surface, where the conditions are conducive to mineral reactions and fluid flow.
成岩作用过程常发生在地球表面几公里内的浅表层，那里的条件有利于矿物反应和流体流动。
- The study of diagenesis provides insights into the history of sedimentary rocks and the environmental conditions present during their formation, as well as their potential as hydrocarbon reservoirs.
对成岩作用的研究提供了对沉积岩历史及其形成过程中存在的环境条件的见解，以及它们作为油气藏的潜力。
