“…The FW analysis is a method that allows identification of debitage techniques based on the crack velocity calculated from microscopic traces on flake scars (see Hutchings 1999;Takakura 2012;Takakura and Izuho 2004). This method has an obvious advantage for analyzing the debitage technique over common ones depending on the morphological observations of the surface features of the study samples.…”

Recent investigations in the Neolithic Southern Caucasus have shed new light on the advent and development of Neolithic culture in the area, which is thought to have emerged around 6000 B.C.E., likely as a result of interaction with the Neolithic communities of bordering regions to the south. Given the geographic and environmental diversity of the Southern Caucasus, the corresponding regional variability of the culture is increasingly attracting attention. Focusing on obsidian pressure blade technology in the region, which is often treated generically so far, this paper investigates the variability in this technology and then makes comparisons among contemporaneous sites. Based on the examination of blade cores obtained from the Neolithic sites of Göytepe and Hacı Elamxanlı Tepe in the Middle Kura Valley, two techno-typologically distinct core types were defined-namely, unifacial and circumferential blade cores. Further, the distribution patterns of the detected technological traces on the surface of the cores, likely caused by firm immobilization for a lever or long crutch pressure debitage, appeared to correspond to the defined core types. Considering the distribution pattern of surface stigmas vis-à-vis the specific blade core type, strategies involving multiple blade production technologies, perhaps each employing different immobilization devices for pressure debitage, can be assumed to be present at the two sites studied. A preliminary comparison with contemporaneous sites on the Ararat Plain in the Araxes Valley provided the basis for considering the regional needs and tradition behind the assumed blade production strategy, probably specific to Middle Kura Valley. Nevertheless, the newly defined and potentially unique unifacial core type may provide a clue to trace technological variability among regions. By exploring the regional variability of the blade production technology through this new perspective, vital questions regarding the Neolithization process or the relationship among groups at that time can be addressed.

“…It is possible to identify flaking techniques from the assessment of crack velocity through the analysis of fracture wings observed on flaking surfaces [66]. In a large proportion of cases in Hokkaido, microblades were systematically detached by pressure flaking, with the exception of some cases [67][68][69][70][71].…”

Archaeological research, for several decades, has shown that various microblade technologies using obsidian and hard shale appeared and developed from the Last Glacial Maximum to the terminal Pleistocene (Bølling–Allerød–Younger Dryas) in Hokkaido, Northern Japan. It is well accepted that microblade technology was closely related to the high mobility of foragers to adapt to harsh environments. Recent archaeological and palaeoenvironmental evidence from Hokkaido demonstrates that the disappearance of microblade technology occurred during the terminal Pleistocene, influenced by a wide range of factors, including changes in landscape, climate, subsistence and human populations. The goal of this paper is to provide an overview of the current state of research on the process and background of the disappearance of microblade technology and to discuss prospects for future research. This paper will (1) review palaeoenvironmental research in Hokkaido on changes in climate and biological composition from the terminal Pleistocene to the initial Holocene; (2) survey changes in the technological adaptations and resource use of humans based on the archaeological evidence; and (3) discuss how the abrupt fluctuations of climate that occurred in the terminal Pleistocene affected human behaviour and demographics in Hokkaido.
