963330 Sample The study will attempt to characterize the temporal and spatial evolution of sources of pore fluids in SOP sites 891 and 892 on the Cascadia accretionary prism. Various mass spectrometric techniques will be used to characterize the chemical and isotopic composition of authigenic carbonates on microdrilled samples across large vein and vug linings. The samples will be dated radiometrically through Th230 method.

本研究将尝试表征Cascadia吸积棱镜上891和892 SOP点孔隙流体来源的时空演化特征。将使用各种质谱技术来表征大静脉和空隙衬里微钻样品上自生碳酸盐的化学和同位素组成。样品将通过Th230法进行放射性测年。
