Geophysical Geological Investigations Palinuro Seamount

项目摘要

The main objective of the project is to establish an areal coverage of electromagnetic (EM) measurements across the Palinuro Seamount (Tyrrhenian Sea, Italy) to allow for the delineation of the lateral and possibly also the vertical extent of a previously detected and drilled seafloor massive sulfides (SMS) as well as for the detection of further unknown occurrences of SMS in the work area. Geophysical measurements are to be accompanied by geological investigations to allow for ground truthing and to yield parameters which are needed for a correct interpretation of the acquired geophysical data. Ultimately the joint interpretation of the acquired data will set up the framework to prepare for planed future investigations, where target-oriented drilling will help to fully characterize the Palinuro Seamount. This will be an important contribution to understand the geology and resource potential of extinct SMS systems in an island arc setting. In a broader sense the we hope to established an ideal test site for novel geophysical and geotechnical exploration tools for eSMS, since its proximity to the coast of Italy makes it a logistically easily accessible target.The work proposed here is technologically new and of interest to both academia and industry:The academic interest lies in the fact that these new EM exploration tools will allow to get a more complete understanding on the distribution of SMS systems in various tectonic settings, since it will help to shift the focus of investigations from the search for presently active systems to those, which are no longer active but potentially have left buried SMS as a hidden geological marker of past activity.The industrial relevance of the research is well documented through the industrial financing of an EM modeling study and equipment design through industry as well as industrial partners in the Blue Mining consortium. These new EM exploration tools can be used to identify buried massive sulfide deposits and derive information on their tonnage allowing a better assessment of the size of sulfide deposits and therefore also providing a better estimate of the resource potential of this type of marine mineral resource.

该项目的主要目标是在Palinuro海山（意大利第勒尼安海）建立电磁测量的覆盖区域，以便对先前探测和钻探的海底块状硫化物（SMS）的横向和垂直范围进行描绘，并在工作区域检测未知的SMS。地球物理测量应伴随着地质调查，以使地面真实，并产生正确解释所获得的地球物理数据所需的参数。最终，对所获得数据的联合解释将建立框架，为计划中的未来调查做准备，其中定向钻井将有助于全面描述Palinuro海山。这将对了解岛弧环境中已灭绝的SMS系统的地质和资源潜力作出重要贡献。从更广泛的意义上说，我们希望为eSMS的新型地球物理和岩土勘探工具建立一个理想的测试地点，因为它靠近意大利海岸，这使得它在物流上很容易到达。这里提出的工作在技术上是新的，学术界和工业界都感兴趣：学术兴趣在于这些新的EM勘探工具将允许对各种构造环境中SMS系统的分布有更全面的了解，因为它将有助于将调查的重点从寻找当前活跃的系统转移到那些。它们不再活跃，但可能留下了埋藏的SMS作为过去活动的隐藏地质标志。研究的工业相关性通过EM建模研究的工业融资和设备设计通过工业以及Blue Mining联盟的工业合作伙伴得到了很好的证明。这些新的电磁勘探工具可用于识别埋藏的大型硫化物矿床，并获得有关其吨位的信息，从而更好地评估硫化物矿床的规模，从而更好地估计这类海洋矿产资源的资源潜力。
