Figure 7. Volume percentage chart(courtesy of AAPG) Self test: Siliciclastic rocks Examine the suite of samples given below. For each sample, attempt an estimation of the amount ( in %)and type of porosity. Each sample is represented by a thin-section micrograph and a micrograph of the drill cuttings. You should attempt to use the cuttings. The thin section micrographs are for assistance only. Answers are given after the references 500um Figure 8. Sample 1.
