Diagenesis quartz cementation

Chlorite in sandstones forms as both early (—20 °C) and late cements and grain replacements (Grigsby, 2001). As described in Section 7.07.4.5, early chlorite may exert a profound effect on porosity in late diagenesis as a result of its inhibitory effect on quartz cementation.

When the diagenesis is isochemical at a scale of 1-lOm, the compaction and shortening (AZ) of a sedimentary sequence (Z) is equal to the porosity loss (A tp ) due to quartz cementation. The reduction in stratigraphic thickness is defined by ... 

The calculated silica balance shows that pressure solution is an important agent for mass transport but by no means the dominant one. Nevertheless, petrographic observations show that the greatest portion of the quartz cement could have been deposited prior to pressure solution. These observations suggest that certain sandstones could have behaved like silica importers during early and as exporters during later diagenesis.
