以往许多研究表明,海底表层(0～1米)沉积物可在低温(低于25℃)生物化学作用下生成 ppb 含量级的C_1—C_8化合物;深部沉积岩发生烃运移的可能极小,而前述原位生化作用
In the past, many studies have shown that sediments on the surface of seafloor (0-1 m) can generate ppb-content C 1 -C 8 compounds under low temperature (less than 25 ° C) biochemistry; hydrocarbon migration in deep sedimentary rocks is extremely unlikely The aforementioned biochemical effects in situ
