Within the project “Arctic Volcanism in Woodfjorden: geodynamic implications (WOODVOLC)” organized by the University Centre in Svalbard and the Department of Arctic Geology, Norway, two volcanic units in the Woodfjorden area NW of Spitsbergen (Miocene-aged basalts of the Seidfjellet Formation and the Quaternary Volcanic Complex of Bockfjorden) will be investigated by petrography, geology/remote sensing, and noble gas geochemistry in fluids, volcanic glass and olivine from mantle xenoliths. Field sampling and mapping of the volcanic structures along with rock magnetic and magneto-mineralogical surveys are envisaged as part of the proposed research project, which can provide fundamental data for magnetic modeling and the emplacement conditions of the volcanic rock units. These data will help better understand the magmatic origin and volcanism that formed these rocks. This is important for a better understanding of the recent geological evolution of Spitsbergen and its onshore geology. Our results will be compared with those of the other working groups and those of alkaline volcanic deposits of Central Europe obtained within the DFG project “Emplacement conditions of pyroclastic deposits inferred from magnetic properties of the Eger maar-diatreme (ICDP-EGER drill site S4) and Eifel volcanoes”.

在由斯瓦尔巴群岛大学中心和挪威北极地质部组织的“伍德峡湾的北极火山活动：地球动力学影响（WOODVOLC）”项目中，斯匹次卑尔根岛西北部伍德峡湾地区的两个火山单元（塞德山组的中新世玄武岩）和博克峡湾第四纪火山群）将通过岩相学、地质学/遥感进行研究，地幔捕虏体中的流体、火山玻璃和橄榄石中的稀有气体地球化学 火山结构的现场采样和绘图以及岩石磁性和磁性矿物学调查被设想为拟议研究项目的一部分，这可以为磁性建模提供基础数据。这些数据将有助于更好地了解形成这些岩石的岩浆起源和火山活动，这对于更好地了解最近的地质情况非常重要。我们的研究结果将与其他工作组的结果以及在 DFG 项目“根据埃格尔马尔迪亚特雷姆的磁性推断的火山碎屑矿床的侵位条件”中获得的中欧碱性火山矿床的结果进行比较。 （ICDP-EGER 钻探地点 S4）和埃菲尔火山”。
