We report preliminary results of a long-term systematic study intended to gather paleoclimatic records from precisely dated speleothems. The research project is limited to speleothems deposited in caves of the Cracow-Wieluń Upland, the largest and best-explored karst region in Poland, covering ca. 2900 km2 with >1000 caves. Speleothem samples were selected from collections of the Geological Museum of the Academy of Mining and Metallurgy in Cracow. Radiocarbon dates of these samples from ca. 45–20 ka bp almost exactly coincide with age range of the Interplenivistulian. A break in speleothem formation between ca. 20 and 10 ka bp may be interpreted as a result of serious climatic deterioration associated with the maximum extent of the last glaciation. We observed differences among 14C, U/Th and AAR dating results. Changes of δ13C and δ18O in speleothems that grew between ca. 30 and 20 ka bp may be interpreted as changes of paleoclimatic conditions.

abstract This paper reports preliminary results of an analysis of the spectral content of seismic waves from over 1,000 local earthquakes in the Garm, Tadjikistan region. Very low values of Q (∼100) were obtained for the Mesozoic and Cenozoic sedimentary rocks of the Peter I Range compared with those in the crystalline rock of the South Tien Shan (Q ≳ 500). For events with the same low frequency spectra, earthquakes in the South Tien Shan are recorded with more energy at higher frequencies than earthquakes in the Peter I Range, at least in part, because of the greater attenuation of the sedimentary rock in the latter region. There is a wide variety of spectra radiated by earthquakes throughout the Garm region, but a marked difference between spectra radiated by earthquakes from these two regions is not apparent. Nevertheless although calculated stress drops of earthquakes appear to vary considerably throughout the region, there appears to be a dependence on the type of rock in which the earthquakes occurred. The variation in calculated stress drops, however, is greater within either region than between the two. For most regions and for most of the range of seismic moments studied the shape of the spectrum is relatively independent of seismic moment. Consequently, calculated stress drops increase with seismic moment, with the functional dependence varying from region to region. For the largest events, the spectrum shifts to lower frequencies with increasing moment and stress drops become essentially independent of moment. Preliminary results suggest that the stress drops are not detectably different for earthquakes with thrust or normal faulting fault-plane solutions. A limited amount of data are consistent with a change in spectral content and stress drop of earthquakes in the vicinity of and before stronger earthquakes but a clear, consistent pattern is not yet evident. Toward high frequencies, S-wave spectra both begin to decrease at lower frequencies and seem to decrease more rapidly than P-wave spectra, in contrast with predictions of published dislocation models of earthquakes.

As Rosenfeld & Smith report in this number of ANTIQUITY, the reconciliation of conventional chronologies for rock-art with the emergent radiocarbon-based dates is not proving an easy affair. Here are the first steps for the classic area of San hunter-gatherer art, on the South Africa/Lesotho border.

This paper describes the results from a project to date Early Bronze Age daggers and knives from barrows in south-west England. Copper alloy daggers are found in the earliest Beaker associated graves and continue to accompany human remains until the end of the Early Bronze Age. They have been identified as key markers of Early Bronze Age graves since the earliest antiquarian excavations and typological sequences have been suggested to provide dating for the graves in which they are found. However, comparatively few southern British daggers are associated with radiocarbon determinations. To help address this problem, five sites in south-west England sites were identified which had daggers and knives, four of copper alloy and one of flint, and associated cremated bone for radiocarbon dating. Three sites were identified in Cornwall (Fore Down, Rosecliston, Pelynt) and two in Devon (Upton Pyne and Huntshaw). Ten samples from these sites were submitted for radiocarbon dating. All but one (Upton Pyne) are associated with two or more dates. The resulting radiocarbon determinations revealed that daggers/knives were occasionally deposited in barrow-associated contexts in the south-west from c. 1900 to 1500 calbc.The dagger at Huntshaw, Devon, was of Camerton-Snowshill type and the dates were earlier than those generally proposed but similar to that obtained from cremated bone found with another dagger of this type from Cowleaze in Dorset: these dates may necessitate reconsideration of the chronology of these daggers

Detailed Picture

Amongst the standing remains of Greco-roman Balboura in northern Lycia are those of two theatres (Fig. 1). The smaller and better preserved clings to the steep south slope of the acropolis hill close to the line of the Hellenistic city's defence wall. The reports of early travellers provide little useful information about the monument, concerned as they are more with Balboura's rich epigraphic material than with her architecture. Spratt and Forbes, who visited the site in 1842 during their archaeological survey of the area, wrote a brief account, and nearly half a century later Petersen and Von Luschan published without comment a single photograph of the stage building's fine retaining wall showing its heavily bossed polygonal stones and its buttresses of squared blocks. No detailed picture was available, however, until the appearance in 1969 of the second volume of de Bernardi Ferrero's monumental survey of the ancient theatres in Asia Minor.The second theatre, located in a rocky bay in the hillside at the edge of the valley three hundred metres to the south, has attracted even less attention, and understandably so, for its remains consist of little more than the foundations for the stage building which lie half buried beneath earth and debris. De Bernardi Ferrero has published several photographs but no drawings. Her brief description concentrates on the system of arches supporting the pavement of the proscenium, an unusual feature for which she cites several parallels in the area.
