Van negen vondsten uit twee fases zijn monsters aangeleverd voor dendrochronologisch onderzoek. Het gaat hierbij om constructiehout van grove den (Pinus sylvestris L.) en fijnspar (Picea abies Karst.) die dateren uit de periode 1600 -  1750 en 1750 – 1900.\nVan de negen vondsten konden er acht aangemerkt worden voor dendrochronologisch onderzoek. Hiervan konden er zeven gedateerd worden.\nVondstnr. 51 kan tot de meest recente fase gerekend worden. De buitenste jaarring valt in 1837 en het lijkt aannemelijk dat het hout ergens in de 19e eeuw gekapt is.\nDe overige dateringen lijken allemaal bij de oudere fase te horen.\nVondstnr. 380 levert een exact kapinterval in de herfst of winter van 1645/46. Voor de resterende dateringen kan geen afgebakend kapinterval bepaald worden, maar deze vallen ná 1645 waardoor het om een andere fase moet gaan. Deze valt waarschijnlijk ergens in de tweede helft van de 17e eeuw. Voor vondstnr. 370 valt de buitenste jaarring in 1560 waarmee het om een oudere fasering lijkt te gaan, maar het ouderdoms verschil van c. 100 jaar met de overige monsters is eerder het gevolg van de bewerking van het hout dan daadwerkelijke verschillen in ouderdom. De onderlinge synchronisaties tussen de vondstnrs. 147, 158 en 370 en de vergelijkbare herkomst geven aan dat het waarschijnlijk om één partij hout met dezelfde ouderdom gaat."},"dsDescriptionDate":{"typeName":"dsDescriptionDate","multiple":false,"typeClass":"primitive","value":"2026-08-24"}}]},{"typeName":"subject","multiple":true,"typeClass":"controlledVocabulary","value":["Arts and Humanities"]},{"typeName":"depositor","multiple":false,"typeClass":"primitive","value":"van Daalen, Sjoerd"},{"typeName":"dateOfDeposit","multiple":false,"typeClass":"primitive","value":"2026-08-24"}]},"dccd":{"displayName":"DCCD Metadata","name":"dccd","fields":[{"typeName":"dccd-projectType","multiple":true,"typeClass":"controlledVocabulary","value":["dating","provenancing"]},{"typeName":"dccd-category","multiple":false,"typeClass":"controlledVocabulary","value":"archaeology"},{"typeName":"dccd-principalInvestigator","multiple":false,"typeClass":"primitive","value":"Sjoerd van Daalen"},{"typeName":"dccd-elementType","multiple":true,"typeClass":"controlledVocabulary","value":["beam","board","post"]},{"typeName":"dccd-taxon","multiple":true,"typeClass":"controlledVocabulary","value":["Picea abies (L.)
