Typical images from the TS and SEM: (a) abundant residual intergranular pores; (b) intraparticle feldspar dissolution pores; (c) interparticle feldspar dissolution pores; (d) the surfaces of the rock particles are covered with rosette-shaped chlorite and the pores are filled with vermicular-shaped kaolinite; (e) the surfaces of the rock particles are covered with the I/S mixed layer, fibrous, and bridge-shaped illite; (f) chlorite, kaolinite, and kaolinite began to develop to shrink pores and throats.
