In 2003-2004 the Ypresian/Lutetian Boundary Stratotype Working Group continued the search of a suitable section in which eventually define the GSSP. The Punta Torcida section in Argentina was visited and sampled, but unfortunately is not a good candidate, since in shallow marine environments, such as the Austral Basin in Tierra del Fuego, there is a […]
In Agost, Alicante province (Spain) was recently found a good section, which seems to be the most suitable candidate for the definition of the Ypresian/Lutetian Boundary Stratotype. It is a new section placed 1 km west of the section studied by Molina et al. (2000). Planktic foraminiferal biostratigraphy indicated that the new section is more […]
The new section found last year in Agost, Betic Cordillera, Alicante province (Spain) has been intensively studied. Biostratigraphy by means of planktic foraminifera, calcareous nannofossils, small benthic foraminifera and larger foraminifera indicated that the section is continuous and quite expanded. The magnetostratigraphical study reveals a series of reversed and normal chrons, which are now being […]
The research has been focused on the study of the two more suitable sections to define the Lutetian GSSP: Agost and Gorrondatxe sections. The results of both sections show that the different events traditionally used to place the Ypresian/Lutetian boundary, previously thought to be almost simultaneous, actually occur at very different levels. The more close […]
After many years searching for a suitable section to define the Ypresian/Lutetian boundary Stratotype, the Gorrondatxe section was found and the Lutetian GSSP was defined in a very expanded and continuous section. The Ypresian/Lutetian Working Group decided, during the final Workshop in Getxo (near Bilbao, Spain) in September 26, 2009, to define the Lutetian GSSP […]
The Ypresian/Lutetian boundary Stratotype was defined at the Gorrondatxe section, which is an excellent very expanded and continuous section. The Ypresian/Lutetian Working Group decided, during the final Workshop in Getxo (near Bilbao, Spain) on September 26, 2009, to propose the Lutetian GSSP at meter 167.85 of the Gorrondatxe section in a dark marly level where […]
Annual Report 2011 of the Ypresian/Lutetian Boundary Stratotype Working Group The Global Stratotype Section and Point (GSSP) for the base of the Lutetian Stage (early/middle Eocene boundary) was defined at 167.85 meters in the Gorrondatxe sea-cliff section (NW of Bilbao city, Basque Country, northern Spain; 43º 22’ 46.47’’N, 3º 00’ 51.61’’ W). This dark marly […]
Annual Report 2012 of the Ypresian/Lutetian On February 13, 2012 the official ceremony to define the Global Stratotype Section and Point (GSSP) for the base of the Lutetian Stage took place in Getxo village and Gorrondatxe beach (Northern Spain). The ceremony started at Getxo village with a press release by Imanol Landa (Major of Getxo), […]
