Yahuay Alta Community Dataset |
The data files EXLITHICS.TXT and EXLITHICS.XLS provide lithic counts for each excavation context of the Yahuay Alta community, organized by material. The data corresponds to Table C.4. (pp. 549) of the dissertation associated with this dataset. EXLITHICS.TXT is an ASCII text file; EXLITHICS.XLS contains the same data in the form of an Excel spreadsheet. Each line represents one collection lot. There are 437 lines in the text file, each with 22 variables separated by commas. The variables are, in the following order:
1 |
Unit. Refers to an excavation unit. Detailed descriptions of Units 1, 2, and 4 can be found on pp. 171-172. Detailed descriptions of Units 3, 5, 6, 7 and 8 can be found on pp. 210-212. |
2 |
Area. The largest subdivision of Units; areas were defined by natural differentiated sections of a unit. |
3 |
Layer. Refers to the natural stratigraphic layers found in each individual unit. Detailed descriptions of the stratigraphy of each unit can be found for Units 1, 2, and 4 on pp. 172-174 and for Units 3, 5, 6, 7 and 8 on pp. 212-215. |
4 |
Quad. The smallest individual subdivision of Units. Quads consisted of 1x1 meter squares that formed a grid over each unit. These grids were numbered sequentially from left to right and from top to bottom, so Quad 1 was always the most northwesternly of the unit. The location of each Quad can be seen in the individual drawings of each unit, Figs. 5.2, 5.4, 5.6, 6.2, 6.5, 6.7, 6.9, and 6.11. |
5 |
Rasgo (Feature). Refers to individual features found in each Unit. These features are quite variable in size and shape. Descriptions of individual Rasgos can be found throughout Chapters 5 and 6 and on the individual drawings of each unit, Figs. 5.2, 5.4, 5.6, 6.2, 6.5, 6.7, 6.9, and 6.11. |

The first line of the ASCII text file, for example, looks like this:
1,A,S,30,-,2,0,0,0,2,0,0,0,0,0,0,0,0,0,0,0,0
This indicates that the data pertains lithics collected in Unit 1, Area A, Layer S, Quad 30. No Rasgo is associated with this lot. It contained a total of 2 lithic fragments, both of which were andesite.
The last, or 437th, line of the ASCII text file is:
8,B,C,52,19,1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0
This indicates that the data pertains to lithics collected in Unit 8, Area B, Layer C, Quad 52, Rasgo 19. It contained a total 1 lithic fragment, which was of Copper Mineral.
