Magnetic prospection at high resolution: survey of large silo-pits in Iron Age enclosures

General issues regarding detection of other anomalously large pits on such sites are also raised. Copyright © 1999 John Wiley & Sons, Ltd.

Isolated chromatin was found to possess a narrow range of microspaces with mean effective diameters between 4.0 and 4.5 nm (40 and 45 A) depending on shape assumptions. Intact nuclei contained a far larger class of free spaces with average diameters in the order of 11.0-15.0 nm. This clearly shows that DNase-I (diam. 4.1 nm) can penetrate and occupy a large proportion of nuclear space even though this enzyme does not readily attack the undisturbed nuclear structure. A structure which simulated the pattern of penetrability and incorporated other known properties of chromatin was used to explain this DNase-I resistance of intact nuclei in terms of an ordered, compact, local structure interspersed by much larger spaces. A system for this local packing is suggested and the functional implications of this type of organization considered.

The effects on ribonuclease activity of variations in pH and temperature, and of Mg'+, Na+, and mononucleotides were examined. The RNase activities (phosphodiesterascs EC 3.1.4.23) were both endonucleolytic, releasing oligonuclcotidea, and cyclic nucleotide intermediates, but exhibited different specificities in releasing mononucleotides from RNA. The ribosomal activity released 3'-GMP, and after prolonged incubation 3'-UMP, but the soluble activity released 3'-GMP, 3'-AMP and 3'-UMP. Neither of the RNase preparations hydrolysed DNA, nor released 5'-nucleotides from RNA. Increased ribosomal RNase activity was related to Mtion of ribosomes, and latency of ribosomal RNase activity was demonstrated. The possible in t&o distribution of RNases is discussed.

A clear impression of the enclosure, with internal areas for habitation and pit-based storage, persists as a pattern of MS enhancement in the topsoil, and such survival may be of interest in the detection and analysis of highly eroded sites elsewhere. Although the habitation area showed well as an area of MS enhancement, its relative transparency to gradiometry provided another example of a larger class of such features, and stresses the importance of supplementing gradiometry with MS survey to provide more adequate assessment of sites. Use of MS survey as a method of prospection is discussed, especially in relation to adequacy of resolution. Application to MS survey of a newly developed, ground-insertable microprobe is briefly introduced as a means of increasing productivity of such surveys.

The barrow, earlier Bronze Age in date, survived as a clay core revetted by two phases of kerbing. Any stone superstructure at the monument, suggested by the large quarry pit adjacent to the mound, did not survive, but had been removed by stone-robbing and plough erosion. Finds included a few low-grade artefacts and animal bone, mainly comprising debris scattered within the mound, perhaps associated with ritual activity accompanying construction. The monument produced two intact deposits of cremated human bone, and included three surviving pyre sites, with the possibility of others suggested by instrumental survey. Supplementary information is presented to provide a background for broader discussion of the monument.
