补充资料:成岩作用
成岩作用 diagenesis 形成岩石的各种地质作用的统称。如岩浆成岩作用、变质成岩作用、沉积成岩作用、花岗岩化作用、混合岩化作用等。通常所说的成岩作用是指沉积物被埋藏后,直到固结为岩石以前所发生的一切物理的和化学的(或生物)变化过程。一般包括沉积物的压实作用、胶结作用、交代作用、结晶作用、淋滤作用、水合作用和生物化学作用等。这些作用通常是在压力、温度不高的地壳表层发生的。当成岩物质被覆盖之后,由于厌氧细菌的作用,有机质腐烂分解,产生H2S、CH4、NH3和CO2等气体,促使碳酸基矿物溶解成重碳酸盐,高价氧化物还原成低价硫化物,酸性氧化环境变为碱性还原环境。此时沉积物质发生重新分配、组合,胶体矿物脱水陈化、压缩胶结,最终固结为岩石。成岩作用一词最早由德国学者C.W.冈贝尔(1868)提出,各国学者对这一名词所赋予的含义并不完全一致。 |
