Petite Rue de Bouchers /Theater Toone (BR 229): Palynological and anthracological research
- 1) The results of the pollen analysis indicate that the pollen deposited at the site comes from a rather open landscape. Most of the trees occur only sporadically or come from the local wetland vegetation (Salix, Alnus, Sambucus). Interesting are the finds of trees which could represent useful or cultivated plants like plum (Prunus-type) and hasel nut (Corylus). A definitely cultivated tree is the walnut (Juglans regia) found in samples from both 11th and 13th century. The herb vegetation, apart of grasses is strongly dominated by pollen of plants growing in disturbed habitats or occurring in the cultivated fields like weeds (Agrostemma githago, Centaurea cyanus, Polygonum convolvulus, Convolvulus sp., Papaver phoeas-type). Those results are also very promising for further integration and comparison with the macrobotanical data. 2) The wood and wood charcoal analyses have indicates that the charred wood was used most probably for fuel as opposed to that deposited in a subfossil state of preservation. The subfossil wood could originate from local vegetation or from activities related with foddering or the use of oak for specific purposes different than fuel. 3) The results of the analyses now are in their final stage and can now be further integrated with those from the macrobotanical and phytolith analyses in order to achieve a better understanding of the plant use at the site.

Hoogstraeten-Lalaing (BR 061): Anthracolgical study
- The wood charcoal analyses of the site Hoogstraeten (BR061) have shown continuity of the used wood fuel through the period of occupation of the site (10-12th to 16-17th century), however the current results should be considered with certain care, as the number of the studied charcoal fragments from the lower Dark Earth layer is rather low. The finds from this layer from indicate reworked wood charcoals, which could considering the micromorphological studies on the site most probably were used as component of the manure spread over the plough layer from which the sample originates. The wood charcoal assemblages from the richest on wood remains structure (US 2230) indicate fuel wood dominated by the most common in the study area woods (beech and oak), but also are characterised by quite high diversity suggest use of all available wood resources.

Lead net-sinkers as an indicator of fishing activities
- Lead fishing-net sinkers in the shape of a small tube, ring, or folded piece of lead sheeting are often identified as scrap metal and/or treated only cursorily in many archaeological reports from Rome’s NW provinces.1 Very few have been illustrated, and measurements and weights are rarely noted. This has led to an under-representation of these finds in the archaeological record. By correctly identifying these lead artefacts and providing the necessary context information, archaeologists can facilitate insights into the various fishing techniques of antiquity and the places where they were practised. This will add information on the local and regional ecology and economy, as well as on dietary habits. Moreover, because the extensive use of lead in the NW provinces began only in the Roman period, finds of lead net-sinkers from well-documented contexts can be used to date indigenous settlements into the Roman period even if they otherwise yield few Roman artefacts. These facts motivated our article, which is therefore not an overview but rather a starting point for research on this artefact type in the NW provinces. We will also raise some questions for future research.

Influence of sedimentological variation on reservoir and source rock characteristics in shale dominated cyclothems (Campine Basin, NE Belgium)
- The KB186 well (GSB 047W0264, Lommel-Kerkhoven) is situated in the northern part of the Campine Basin (NE Belgium) to the west of the Donderslag fault and has been studied and sampled in detail from a depth of 1182.72 meters to 1197.75 metres. The objective is to examine the sedimentological, petrographical, mineralogical and petrophysical characteristics and their variations within and between two cyclothems. 17 shale samples were taken throughout the entire section, varying from roof shales, over dark organic-rich shales with siderite enrichments, to bluish-grey shales without no visible organic content. Two sedimentary cycles have been recognised. Macroscopically, they show some similarities and differences in facies and sedimentological trends. Both are approximately 6.5 metres thick and contain sections of mainly shale deposits (with or without siderite enrichments). Fining-upwards sequences of fine sand and clayey silt and larger sandstone bodies occur between these shale-rich sections. A petrographical assessment by means of optical light and electron microscopy is conducted for a qualitative analysis of the mineralogical composition and diagenetic history, while a quantitative determination is made by means of x-ray diffractometry. Important mineralogical reservoir parameters are the relative amounts of silica and quartz, and the clay mineralogy with special attention to smectite and illite.
