However, the distribution law of lithofacies and groundwater depends on global sea-level changes and tectonic activities as the two most important reasons. Quaternary sediments of the Red River delta downstream have 5 sediment cycles corresponding to 5 sequences: (1) sequence 1 with Early Pleistocene age (Sq<sub>1</sub>–<span>({text{Q}}_{1}^{1})</span>); (2) sequence 2 with early Middle Pleistocene age (Sq<sub>2</sub>–<span>({text{Q}}_{1}^{{2{text{a}}}})</span>); (3) sequence 3 with late middle Pleistocene age (Sq<sub>3</sub>–<span>({text{Q}}_{1}^{{2{text{b}}}})</span>); (4) sequence 4 with early Pleistocene age (Sq<sub>4</sub>–<span>({text{Q}}_{1}^{{3{text{a}}}})</span>); (5) sequence 5 with late Pleistocene–Holocene age (Sq<sub>5</sub>–<span>({text{Q}}_{1}^{{3{text{b}}}})</span>–Q<sub>2</sub>). Each sequence is composed of three sedimentary systems tracts. The lowstand systems tract (LST) is characterized by a lowstand alluvial muddy sand facies complex that acts as a primary freshwater aquifer (S<sub>m</sub>arLST). The transgressive systems tract (TST) is characterized by a coastal swamp sand mud facies (M<sub>s</sub>amtTST) and a maximum transgression bay-lagoon mud facies (MmtTST) acting as an aquifuge. The highstand systems tract (HST) is characterized by sand bar facies (SamhHST) and delta plain sandy mud facies (M<sub>s</sub>amhHST). Thus, vertically Pleistocene sediments have 5 aquifers, in which each aquifer is constituted by the superposition of two successive facies complex: (1) upper part: lowstand alluvial gravelly sand facies complex (LST) and (2) lower part: highstand dune sand bar facies complex (SarLST/SamhHST).

This fact indicates the existence of decompaction zones in the crust and upper mantle related to serpentinization that can also provoke the superimposed, probably modern, chemogenic magnetization and distortion of the primary linear pattern of magnetic anomalies in the oceanic basement in the study area. Serpentinization was also responsible for vertical displacements of the crustal and upper mantle blocks on the flanks, leading to deformations of the sedimentary cover with the rock dilation. Off-axis seismicity indicates tectonic disruptions on flanks of the ridge with a higher access of water necessary for the serpentinization and the subsequent change in the physical properties of rocks reflected in geophysical fields.
