Line 50:
Line 50: − Detrital clays can be part of sandstone matrix or grains. As matrix, detrital clays can obliterate permeability. Detrital grains of clay are often ductile and can be compacted into pore spaces during burial. The percentage of detrital clay in a rock determines permeability. The figure below shows different types of detrital clays in a sandstone. − + + +

Detrital clays can be part of sandstone matrix or grains. As matrix, detrital clays can obliterate permeability. Detrital grains of clay are often ductile and can be compacted into pore spaces during burial. The percentage of detrital clay in a rock determines permeability. [[:file:predicting-reservoir-system-quality-and-performance_fig9-63.png|Figure 4]] shows different types of detrital clays in a sandstone.
