Introduction

So far definitions from 595 features and aggregates from A15 have been tabulated. (Features and aggregates share the same definitions and categories. A second section lists only the aggrgates which contributed to the total) Buildup (accumulations and layers) comprise 40% of the total, with ordered aggregation (walls and installations) the next highest at 37%.

Tabulations

The following are the groupings by category:

type	total	percent
build-up (accumulations, layers)	236	40%
amorphous amassment (fill, gully)	48	8%
ordered aggregation (walls, installations)	223	37%
horizontal surfaces (floors, pavements)	86	14%

Aggregates

As useful as the data on features and items may be, aggregates (collections of elements across cagtegories) are vital to understanding how each stratum was organized and used. For example a room comprises walls, floors, doorways, and items within, thus revealing the rationale for and the activities enabled by the construction. There were 58 such aggregates grouped as follows:

Type	Number	Percent
structures	20	34%
pits	16	28%
burials	9	16%
installations	8	14%
soil	4	7%
ceramics	1	1%

Discrepancies

This table lists 595 elements; however, the constituent list totals 597 elements. At least one feature, f260, can be attributed to errors in ceramics tabulations. These errors will be reconciled after the ceramics analysis is completed.
