The　Upper　Devonian　Hongguleleng　Formation　is　a　significant　stratigraphic　unit　near　the　Frasnian/Famennian　and　Devonian/Carboniferous　boundaries　of　the　Kazakhstan　Paleoplate.　However,　its　age　is　still　under　debate.　A　new　palynostratigraphic　analysis　was　conducted　at　the　Gennaren　section　to　provide　a　more　accurate　biostratigraphic　assignment.　In　this　study,　we　identified　43　species　belonging　to　26　spore　genera,　including　those　in　open　nomenclature.　Despite　the　poor　preservation　of　the　palynofloras,　the　spore　taxa　were　categorized　into　two　assemblages.　Assemblage　I　is　established　at　the　lower　part　of　the　lower　member　of　the　Hongguleleng　Formation,　containing　Cornispora　varicornata,　cf.　Auroraspora　pseudocrista,　and　Cyrtospora　cristifera.　Assemblage　II　is　from　the　upper　part　of　the　lower　member　of　the　Hongguleleng　Formation,　including　Grandispora　cornuta,　Grandispora　famennensis　var.　famennensis,　Grandispora　cf.　famennensis　var.　minutus,　Grandispora　microseta,　and　Rugospora　radiata.　These　assemblages　are　compared　with　the　Western　European　DV　Oppel　Zone　(lower-middle　Famennian),　and　the　GF　to　VCo　Oppel　zones.　The　assemblages　are　equivalent　to　the　conodont　crepida-rhom-　boidea　and　marginifera　to　Lower　trachytera　zones　(middle-upper　Famennian).　(c)　2024　Elsevier　B.V.　and　Nanjing　Institute　of　Geology　and　Palaeontology,　CAS.　All　rights　are　reserved,　including　those　for　text　and　data　mining,　AI　training,　and　similar　technologies.
