The Funabuseyama Formation is a thick pile, up to 800 m thick, of shallow-marine limestones with basaltic volcaniclastics in the basal part. The lower part of the formation (Pseudofusulina ambigua Zone) consists mostly of black, bedded, highly carbonaceous, algal and molluscan wackestones, with some interbeds of laminated bioclastic packstone. The middle (Parafusulina kaerimizensis Zone) comprises light grey, structureless, fusuline-crinoid wackestone and intraclastic bioclastic grainstone. The upper (Neoschwagerina margaritae-Yabeina globosa Zone) is composed of dark grey structureless to thick-bedded, fusuline wacke/packstone. The limestones are of a bank-formed shallow-marine buildup most possibly on a basaltic seamount in an open-ocean setting. -from Author
