Magnetostratigraphy of Mio-Pliocene Italian Land Sections

海洋沉积物的地层对比是 海洋地质学 磁性地层学提供了一种全球性的 与沉积环境无关的相关性。 需要 为快速古环境研究提供时间框架 变化，需要将不同的生物区带联系起来， 生物地层事件的同步性，增强了 磁性地层学的重要性。 晚中新世-上新世 间隔对于生物磁性地层对比仍然是个问题。 这些相关性在公开场合也没有得到很好的确立 海洋或地中海地区，其中中新世层型 部分位于。 PI将从以下方面推导磁性地层学： 在意大利特定的土地部分，并在这样做的相关中新世-上新世 层型剖面的地磁反转时间尺度，并提供 地中海和公海生物分区之间的第一个联系。 这 也将使古气候事件之间的相关性， 地中海和公海，并阐明了原因， 地中海盐度危机。 收购 地中海新近纪的磁性地层学一直是一个难以捉摸的 目标，岩性不是理想的磁性地层学。 然而，初步研究表明， 采样将提供生物磁性地层的相关性， Serravallian（中中新世）至上新世-更新世边界。

Stratigraphic correlation of marine sediments is the cornerstone of marine geology. Magnetostratigraphy provides a unique method of global correlation that is independent of depositional environment. The need to provide a time-frame for investigating rapid paleoenvironmental changes, the need to correlate diverse biozonations and to investigate the synchroneity of biostratigraphic events, has enhanced the importance of magnetostratigraphy. The Late Miocene to Pliocene interval is still problematic for biomagnetostratigraphic correlations. These correlations have not been well established either in the open ocean or in the Mediterranean region, where the Mio-Pliocene stratotype sections are located. The PI will derive magnetostratigraphies from specific land sections in Italy, and in so doing correlate Mio-Pliocene stratotype sections to the geomagnetic reversal time scale and provide a first link between Mediterranean and open ocean biozonations. This will also allow the correlation of paleoclimatic events between the Mediterranean and the open ocean, and shed light on the cause of the Mediterranean salinity crisis. The acquisition of magnetostratigraphies in the Mediterranean Neogene has been an elusive goal, and the lithologies are not ideal for magnetostratigraphy. However, initial studies demonstrate that the sections which will be sampled will provide biomagnetostratigraphic correlations from the Serravallian (Middle Miocene) to the Plio-Pleistocene boundary.
