本文描述了纳瓦拉Estella-Lizarra底辟周围出露的Zufia组（厚1580 m）的沉积学、沉积环境和生物地层学。这一地层的年龄是阿尔比晚期到赛诺曼早期，代表了迄今为止在西班牙北方巴斯克-坎塔布连地区已知的这一时间间隔的最完整的继承。从砂岩到泥灰岩和灰屑岩，层序向上演化。沉积学表明，沉积在浅海环境中，从三角洲前缘的砂坝延伸到通常低于风暴浪基面的近海区域。在它里面，重要的非层序是存在的，可以与当地或区域的海平面变化，并提供了一个测试目前的晚Albian和Cenomanian全球海平面变化模型。生物地层数据从分散的菊石和良好的有孔虫发生日期的形成与底栖，游泳和浮游动物群之间的准确校准。序列的下部（880 m）属于特提斯省的Hysteroceras varicosum和Mortoniceras inflatum（严格意义上）菊石带。Stoliczkaia dispar带由460 m的沉积物代表，其中210 m属于Mortoniceras（Mortoniceras）rostratum亚带，250 m属于Mortoniceras（Durnovartes）perinflatum和Arrhaphoceras（Praesophenbachia）briacensis亚带，基于菊石产状。根据浮游有孔虫的证据，Arrhaphoceras（Praesophenbachia）briacensis亚带可能由另一个40米的最新Albian时代的沉积物代表，尚未产生菊石。最高的240米的祖菲亚组是早期赛诺曼的日期为基础，基本上，在南极有孔虫的证据。该剖面上方有100 m的Ollogoyen组中塞诺曼阶沉积物。很少有菊石是已知的从这个森诺曼继承。在生物地层学上，它与法国南部的Vocontian海槽有密切的相关性。
The sedimentology, depositional environment and biostratigraphy of the Zufia Formation (1580 m thick), which crops out around the Estella-Lizarra diapir in Navarra, is described. The age of this formation is Late Albian to Early Cenomanian and represents the most complete succession of this time interval known so far in the Basque-Cantabrian region of northern Spain. The succession evolves upward from sandstones to marls and calcarenites. The sedimentology indicates deposition in a shallow marine environment extending from delta front prograding bars into an offshore region generally below storm-wave base. Within it, important non-sequences are present which can be correlated with either local or regional changes in sea level and provide a test of current Late Albian and Cenomanian global sea-level change models. Biostratigraphical data from scattered ammonite and good foraminiferal occurrences date the formation with accurate calibration between benthic, nektonic and planktonic faunas. The lower part of the succession (880 m) belongs to the Hysteroceras varicosum and Mortoniceras inflatum (sensu stricto) ammonite Zones of the Tethyan province. The Stoliczkaia dispar Zone is represented by 460 m of sediment of which 210 m belongs to the Mortoniceras (Mortoniceras) rostratum Subzone and 250 m to the Mortoniceras (Durnovarites) perinflatum and Arrhaphoceras (Praeschloenbachia) briacensis Subzones, based on ammonite occurrences. On planktonic foraminiferal evidence, the Arrhaphoceras (Praeschloenbachia) briacensis Subzone may be represented by a further 40 m of sediment of latest Albian age which have not yet yielded ammonites. The uppermost 240 m of the Zufia Formation is of Early Cenomanian date based, essentially, on planktonic foraminiferal evidence. The section is surmounted by 100 m of Middle Cenomanian sediments of the Ollogoyen Formation. Very few ammonites are known from this Cenomanian succession. Biostratigraphically, there is close correlation with the Vocontian Trough of southern France.
