the hydrocarbon emplacement (Fig. 2(i)) [39, 51] which improved the rock compressive resistance [52], so the pores formed before dolomitization were well preserved. 5.1.2 Early fast deep burial and hydrocarbon... or completely closed shortly after the deposition. Primary and eogenetic secondary pores were well preserved due to the early fast deep burial, minimizing the time for compaction and cementation. Because......
