Cement Distribution patterns as a function of diagenetic environment 

Cement Distribution patterns as a function of diagenetic environment
Description: A) In the vadose zone cements are concentrated at grain contacts and the resulting pores have a distinct rounded appearance due to meniscus effect. The resulting cement pattern is termed meniscus cement
B) In a vadose zone immediately above water table there is often excess of water that accumulates at the base of grains as droplets. These cements are termed microstalactitic cements.
C) In the phreatic zone, where pores are saturated with water, cements are precipitated as circumgranular crusts.
