资源简介：
This file consists mainly of information recorded by Lynette Heller concerning the variables employed in obsidian analysis, with later clarifications by Barbara Stark. It included two addenda, one by Lynette Heller grouping codes according to production technology, and the other noting some special circumstances affecting a few obsidian collections. The obsidian files from PALM 1 and PALM2 are not constructed the same way (PALM 2 is non-relational), and the obsidian coding is not thoroughly documented.
