![]() ![]() Many of these sites appear to have emphasized manufacture of ovate biface-preforms as the main form in which obsidian was redistributed beyond the mountain source. Site 'trains', or series of functionally differentiated workshops and campsites are distributed around the primary obsidian sources at lower elevations near the treeline. The outside texture of the specimen may look like a rock, but thats just what slag glass looks like when it cools in the dirt or surrounding sediment, it picks up much of the surrounding sands and soils if it wasn. One of these varieties, a distinctive green obsidian with a gold hue referred to as Sierra de Pachuca 1 or Las Minas Green, was extensively mined during and after the rise of the Teotihuacán state between 100 BCE and 550 ce (Ponomarenko, 2004), and appears to have formed the basis for large-scale craft production at Teotihuacán (Hirth et al., 2019). ![]() There are certainly more varieties out there, but this will cover the vast majority of real obsidian on the market. and the onset of cooler Neoglacial climates.

Natural green obsidian does exist but is extremely rare, and looks almost black unless you are looking through a rather thin slice. The following are different varieties of the mineral with no attention to form. Preliminary excavation results and paleoenvironmental reconstructions suggest that the concentrated alpine obsidian sources were probably most intensively exploited prior to 3000 B.P. Archaeological investigations reveal primary concentrated obsidian outcrops and quarry sites at high elevation, as well as lower and more dispersed areal scatters of raw material. Mt Edziza obsidian has been utilized by native people for 9-10,000 years and widely distributed throughout surrounding regions. Results of a first-stage archaeological reconnaissance of the Mt Edziza obsidian source area in northwestern British Columbia, Canada, are described. ![]()
