Abstract:

Lower Cretaceous Albian in block AofLower CongoBasin deposited a set of carbonatemixed facies composed of terrigenous sand and mud. Based on regional geologic setting, logging geology, seismic data and thin section observation, the mixed deposition of Albian in the study area is analyzed. The research result shows that:①The profile structure is characterized by 4 types, including alternating deposits of terrigenous debris and carbonate, alternating deposits of terrigenous debris and diamicton, alternating deposits of carbonate and diamicton, and alternating deposits of diamicton themselves; ②A mixed deposition mechanism appropriate for the study area is proposed, called “discontinuity- overlapping” mixed deposition, and the mixed deposition model is established; ③With the seawater entering and the expansion of transgression, the Albian experienced mixed gentle slope, mixed restricted platform, mixed open platform and mixed continental shelf successively, and developed numerous sedimentarymicrofacies such as lime mud mound, sandy shoal, oolitic beach, bioclastic shoal, algal-clastic beach, subtidal static water mudstone and tempestite.
