The “Falizette”  section yielded acritarchs of zone 4 (locally 4b) similar to assemblages observed earlier (Vanguestaine, 1978) in the “Givonne” and “ Hatrelle” valleys of the Givonne Inlier. In the “Terne de la Borne” section, the strata described as belonging to the Illy  Formation and most part of the Sautou Formation, the latter in its type locality, provided acritarchs of zone 2 (and possibly 1)  and do not correlate therefore with the Rv3 and the Rv4 of the Rocroi Inlier but with Rv2 (and possibly Rv1) of the same area.  This correlation is reinforced by the observation in the sequence of a roo? ng slate seam, previously undescribed, a possible  equivalent of the Peureux Member, characterizing the upper part of Rv1 in the Rocroi Inlier. Besides specimens pointing to an acritarch biozone 2 assemblage, the richest sample of the Sautou Formation also yielded rare  examples of acritarch species which have not previously been recorded in Belgium or the surrounding areas. They are Adara  alea, Celtiberium geminum, possibly  Eliasum llaniscum, Multiplicisphaeridium martae  and  Retisphaeridium postae. The  probable metazoan Ceratophyton vernicosum has also been observed. Compared to the well dated Newfoundland Cambrian  succession, acritarch biozones 2 assemblages indicates a mid Middle Cambrian age. This new chronostratigraphic result not  only allows a better calibration of the Belgian acritarch zonation with respect to the acritarch and trilobite international zonations  but also con? rms our interpretation of the lithostratigraphic succession.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"New biostratigraphic and chronostratigraphic data from the Sautou formation and adjacent strata (Cambrian, Givonne inlier, Revin group, Northern France) and some lithostratigraphic and tectonic implications","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Acritarchs, Revin Group, Givonne Inlier, northern France, Middle-Upper Cambrian, lithostratigraphy,  chronostratigraphy","OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2013-05-03","DateCreate":"2013-01-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":221967,"PubliDate":2005,"Pagination":"131-144","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45707,"SerRR":"Geologica Belgica.
