The purpose of this study is to conduct investigations into the morphological characterstics and chemical compositions of the microlites included in the obsidians from the North Korean side Baekdusan (NK) and in the obsidian artefacts from the Busan Gadeokdo prehistoric site (BG).
I used some obsidian samples originated from the southern flank of the Baekdusan, North Korea(hereafter NK obsidian). The REE patterns for the NK obsidians are generally in harmony with those for the previously reported obsidians from the northern flank of Baekdusan, China. Recently a Neolithic site was discovered in the southern part(Busan Gadeok-do) of South Korea, and there found lots of the obsidians with those for the NK obsidians. There exists a prominent contrast between them, suggesting that the obsidians are different in provenance. The BG obsidians are presumably correalted to the volcanic rocks in the Kyushu, Japan.
The morphology of the microlites from the NK can be divided into three groups, and trichite-acicular and trichite-asteroidal types are predominant. On the other hand the microlites from the BG show various morphological features such as acicular, margarite, lath, and asteroidal types. Silicate microlites from the NK are mostly of Ca-pyroxene compositions (hedenbergite to augite), whereas those from the BG are mostly of biotite (annite) with small amount of clinopyroxene (ferrosilite). It is well understood that the microlites from the NK are different from those from the BG in terms of the morphology, mineral content and mineral composition. Thus the obsidian artefacts from the Busan Gadeokdo prehistoric site seem to have no genetical relationship to the obsidians from the Baekdusan.
