Disaggregation

Introduction

In J1 the specific nature of the area make the disaggregation processes not well attested. Not many structures have been found and the few structures have been used for long periods and are well preserved. Possibly there is only one collapse attested. The most common disaggregation process is the erosion that instead is well recorded.

Collapse

     At the base of the stone structure dated to the Late Chalcolithic many large collapsed stones were found (f336). They lay almost flat in an irregular pattern, clearly showing an important and single collapse episode. The stones dicrease in number going far from the structure(v443). The walls show damage evidences, but because the area is highly affected by later intrusions (cut and new structures) we are not sure if the walls are collapsed for natural or human reasons.

Erosion

The erosion processes is one of the main causes of damagefor J1 structures. The erosion is due to water flowing, coming from the West, where probably the ancient tell was higher. The water flowed likely along the base of the Revetment wall closed to the South by other buildings and ran into the Plaza. To protect the base of the wall along its western face an impressive stone escarpment (see J5) was built that stops next to J1. The water erosion (f378) damaged the clay J1 escarpment f196 and forced to build a new large escarpment ^esc2. The water probably could be the reason (f344) for the collapse of the stone structure.
