Stratigraphy
Phase 3n is a short period of modification in J1, where the changes are mainly due to problems arisen from the water flowing. We can identify two different moments:
- (s640bJ1A) A lot of water was supposed to come from West, causing a strong damage to the surface of the First Escarpment. This erosion was very dangerous for the stability and integrity of the Revetment Wall.
- (s640aJ1A) Following this damage there was probably a short period of abandonment, resulting in layers of debris and ash covering the eroded surface of the Escarpment.
