    Authigenic kaolinite in sandstone occurs most commonly as fragile aggregates of crystals between sand grains, in vugs, along fractures, and as grains. It may form by crystallization from solution, by alteration of a parent mineral in place, and by recrystallization of fine-grained detrital kaolinite clay.

    The most common eogenetic clay minerals are kaolinite, dioctahedral and trioctahedral smectite, berthierine, glauconite and, less commonly, Mg‐rich clay minerals such as palygorskite. The distribution of eogenetic clay minerals is strongly related to depositional facies and sequence stratigraphic surfaces.
