Introduction

In J7 layering and gradual build-up define the latest deposits in the area. After the brickfall there is a gradual build-up natural accumulations (namely, lens D).

Lenses

There are 27 accumulations in J7, the majority (21) of which are natural lenses (lens d). As the area remained open it is expected to find it filled up gradually with natural accumulations deposited by wind and water.
There is one lens, f13, which is a relatively flat accumulation of sherds and pebbles, however, none of the sherds or pebbles were lying flat so it is assumed that this feature was either a dump or a natural accumulation caused by water.

The remaining 5 accumulations are assigned to topsoil, a very specific type of lens that refers to the top accumulations of the tell. These accumulations are often contaminated with modern materials.

Layers

There is one very clear layer in J7, which is the layer of ash, f58. It was only identified in section but is very clear. It has clear upper and lower boundaries and marks a distinct event.
