Quijos Settlement Dataset |
The data files OBSEXC.TXT and OBSEXC.XLS contain data on all the obsidian artifacts from excavations at Quijos settlements. OBSEXC.TXT is an ASCII text file; OBSEXC.XLS contains the same data in the form of an Excel spreadsheet. Each line represents one artifact. There are 722 lines in the text file, each with 15 variables separated by commas. The variables are, in the following order:
| Stratigraphic test number | |
| Stratigraphic level | |
| Color: 1=Gray 2=Green 3=Clear 4=Smokey, translucent gray |
|
| Sub-color: 1=Black 2=Grey 3=Black in middle, transluscent on edge 4=Bottle clear 5=Bottle clear with clouds 6=Cloudy 7=Banded 8=Smokey (transluscent) 9=Grey, Green/Bluish 10= Cloudy with speckles 11=Mottled Black/Grey |

The first line of the ASCII text file, for example, looks like this:
VQ001,1,1,3,8.7,8,1,31,38,9,5,3,2,10,1
This indicates that the artifact is from stratigraphic test VQ001, level 1. Its color is gray, and its sub-color is black in the middle with translucent edges. It is a secondary decortication flake (debitage). The platform has a single facet. The length of the flake is 31 mm; the width, 38 mm; and the thickness, 9 mm. Edge wear is steep, regular microflaking (scraping), on both faces. The tool is classified as a side scraper. Its weight is 10 g, and the termination type is step.
The last (721st) line of the ASCII text file is:
VQ030,12,1,1,8.8,,,21,16,8,5,4,2,2.3,
This indicates that the artifact is from stratigraphic test VQ030, level 12. Its color is gray, and its sub-color is black. It is classified as chunks and shatter (flake debitage). The stage is undetermined, and the platform is unidentified (crushed). The length of the artifact is 21 mm; the width, 16 mm; and the thickness, 8 mm. Edge wear is steep, regular microflaking (scraping), on an undetermined face. The tool is classified as a side scraper. Its weight is 2.3 g. The termination type is undetermined.
