Summary: Two types of clinoptilolite occur, representing different diagenetic conditions: type A found in stratigraphically condensed sediments could indicate early diagenesis, while type B formed after the opal-A to opal-CT transformation indicates later diagenesis. The silica source for clinoptilolite is biogenic opal.
