Rocks are heavy: transport costs and Paleoarchaic quarry behavior in the Great Basin

Central place foraging models are used to investigate assemblage variability at two Paleoarchaic (terminal Pleistocene/early Holocene) dacite quarries in the central and eastern Great Basin. Our analyses focus specifically on biface reduction and how varying degrees of reduction relate to the costs of transporting the resulting products upon departing the quarry. Our results suggest that when the distance to be traveled to a residential base is great, reduction will proceed further at the quarry than if the residential base is fairly close. Further, a residential site assemblage will consist of bifaces at later stages of reduction than its associated quarry.     

The Roman quarries at Antinoopolis (Egypt): development and techniques

The aim of this research was the survey and the study of the many quarries located in the first spurs of the Gebel el-’Adila, close to Antinoopolis (Middle Egypt). These quarries are an excellent opportunity for observation and research concerning the “landscape archives” and preserve traces of man’s activity, representing a real cultural heritage. The paper gives a short geological setting of the area and reports our recent study (2006 onward) on traces, typologies, methods and development of the quarrying activity in the area, focussing on the Roman period. The working traces allowed us to define the working tools used for quarrying, the organisation of the works and of the quarry exploitation, as in the area many remains of the quarry organisation network are extant or recognisable, such as: service posts, sledge-ways, docks.     

Making time: ‘Living floors’, ‘palimpsests’ and site formation processes – A perspective from the open-air Lower Paleolithic site of Revadim Quarry, Israel

The recognition of the dynamic role of site formation processes led archaeologists to recognize a behavioral dichotomy between ‘living floors’ and palimpsests’, Yet the archaeological proxies of ‘living floor’ and ‘palimpsest’ were never defined formally, and therefore have been used variably. We use archaeological criteria mentioned in the archaeological literature to model types of formation processes. The case study of the Lower Paleolithic open-air site of Revadim Quarry, Israel is used to test the model. Two types of palimpsests, differing in the rate of accumulation and thus in their effects on the anthropogenic remains, were discerned. Based on these results we review some other Lower Paleolithic instances. A sliding scale of formation processes provides a much needed middle ground between the scales of coarse, time-averaged formation processes and short, “near real-life” behavioral episodes and is an appropriate archaeological frame of reference.     

INAA of pre-contact basalt quarries on the Samoan Island of Tutuila: a preliminary baseline for an artifact-centered provenance study

This project presents a material-centered instrumental neutron activation analysis (INAA) characterization of 120 geologic samples selected from four fine-grained basalt quarries on the Samoan Island of Tutuila. Previous attempts at definitive differentiation of these Tutuilan quarries have utilized x-ray fluorescence (XRF). In this study, clear differentiation of each analyzed quarry was achieved using INAA. Biplots of canonical discriminant analysis (CDA) scores for the INAA data illustrate clear separation based on the variation in chemical composition between each quarry. The samples analyzed not only define quarry separation, but also provide the “core group” for a preliminary baseline necessary for future artifact-centered provenance studies. Inclusion of these “core group” samples in the baseline was confirmed by stepwise discriminant analysis. These findings suggest the ability to determine artifact quarry of origin on the island of Tutuila, which can elucidate the importance of individual Tutuilan quarries in the production, distribution and consumption of fine-grained basalt artifacts in Polynesia.     

Consideration on the construction process and the sandstone quarries during the Angkor period based on the magnetic susceptibility

Detailed magnetic susceptibility measurement was conducted on the sandstones used for the Angkor monuments constructed in the period spanning the Preah Ko and Angkor Wat styles, and the construction process of the buildings and quarries of the sandstones was considered. Combined with the previous study on the sandstones of the Bayon style [Uchida, E., Cunin, O., Shimoda, I., Suda, C., Nakagawa, T., 2003. The construction process of the Angkor monuments elucidated by the magnetic susceptibility of sandstone, Archaeometry 45, 221–232], the magnetic susceptibility measurement revealed that there were 7 sandstone quarries corresponding to Stages I, II, III, IVa, V, VII and VIIIb during the Angkor period. The sandstones used for the monuments belonging to Stage I show average magnetic susceptibility values ranging from 1.1 to 2.3 × 10⁻³ SI units. In the Bakheng style period (Stage II), the average magnetic susceptibility of the supplied sandstones decreased gradually from around 10 to 1 × 10⁻³ SI units over time. The magnetic susceptibility range of the sandstones used for the monuments of Stage III was from 2.3 to 3.0 × 10⁻³ SI units. In the early Angkor Wat style period (IVb), the average magnetic susceptibility of the supplied sandstones increased over time, reflecting the supply of the sandstones from two different quarries, that is, the quarry corresponding to the Khleang and Baphuon style monuments (Stage IVa), with low average magnetic susceptibilities of 1.1 to 2.4 × 10⁻³ SI units, and the quarry corresponding to the main Angkor Wat style monuments (Stage V), with high average magnetic susceptibilities ranging from 2.8 to more than 4.3 × 10⁻³ SI units. The sandstones of Stage VII show low average magnetic susceptibility around 1 × 10⁻³ SI unit. The sandstones of Stage VId is a mixture of sandstones of Stages V and those of Stage VII. The sandstones with high magnetic susceptibilities are found in the monuments belonging to Stage VIIIb, reflecting the supply from the new sandstone quarry.     

Energy-Dispersive X-Ray Fluorescence analysis of Haleakalā basalt adze quarry materials, Maui, Hawai‘i

One of Hawai‘i’s major prehistoric basalt adze quarries (SIHP 50-50-11-2510) is located in the summit region of Haleakalā, Maui. Situated at approximately 2750 m above sea level (9000 ft), the quarry shares a similar high-altitude setting with the Mauna Kea adze quarry on Hawai‘i Island. Adding to a growing Energy-Dispersive X-Ray Fluorescence (EDXRF) database for the Hawaiian Islands, we present the results from 255 geological and archaeological lithic samples from the Haleakalā quarry site. We also briefly discuss why this non-destructive XRF technique is particularly applicable in the Hawaiian cultural context.
