diagenesis

The main diagenesis developed during the LST period is fargoing karstification in the exposed area.

结果表明，与LST有关作用主要为范围广泛暴露溶蚀作用；

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，斜长石钠长石化可见于早期，而钾长石钠长石化发生于晚期。

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

埋藏作用可使蒙脱石进一步转化，最终产物决定于PH值及孔隙水化学性质。

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.

在它作用之前，它含有燧石质胶结分。作用过程中，低温抵压改变了沉积物分，而后固结。
