Burial diagenesis causes a progressive transformation of smectites, the end-products being dependent on PH and pore water chemistry.

埋藏成岩作用可使蒙脱进一步转，产物决定于PH值及孔隙水的学性质。

Therefore, the albitization of plagioclase is shown in the early stage of diagenesis and albitization of potash feldspar appears only in the late stage of diagenesis.

因此，斜的可见于成岩早期，而钾的只发生于成岩晚期。

This rock contained chalcedonic cement before it underwent diagenesis, a process where low temperatures and low pressures alter the content of sediments before they finally lithify, or turn into rock.

在它经历成岩作用之前，它含有燧质的胶结成分。成岩作用过程中，低温抵压改变了沉积物的成分，而后固结成岩。
