X-ray fluorescence (XRF) data of sediment core GeoB24351-1, 30 kV run

X-Ray fluorescence (XRF) scans were carried out for core GeoB24351-1 (Gelendzhik MV; 0-284 cm) in 10 mm steps downcore on the split core surface of the archive half with the XRF Core Scanner III (AVAATECH Serial No. 12) at MARUM – Center for Marine Environmental Sciences in Bremen. To avoid contamination of the XRF measurement unit and the desiccation of the sediment, the split core was covered with a 4 µm thin SPEXCerti Ultralene1 foil. Reported data was acquired with a SGX Sensortech Silicon drift detector (Modul S SiriusD®D65133Be-INF with 133 eV X-ray resolution), a Topaz-X High-Resolution Digital MCA, and an Oxford Instruments 100 W Neptune X-Ray tube with rhodium (Rh) target material. Data were obtained during three runs at 50 kV (1st run), 30 kV (2nd run) and 10 kV (3rd run). Processing of raw data took place by the analysis of X-ray spectra by an iterative least square software package from Canberra Eurisys (WIN AXIL).针对岩芯GeoB24351-1（Gelendzhik MV；0~284 cm），于不来梅海洋环境科学中心MARUM（MARUM – Center for Marine Environmental Sciences），使用XRF岩芯扫描仪III型（XRF Core Scanner III，AVAATECH序列号12号），对存档半岩芯的分半岩芯表面以10 mm步长沿岩芯深度方向完成扫描。为避免XRF测量装置受污染以及沉积物脱水，实验过程中采用4 µm厚的SPEXCerti Ultralene1防护箔覆盖分半岩芯。本次报告的实验数据由以下设备采集：SGX Sensortech公司硅漂移探测器（型号Modul S SiriusD®D65133Be-INF，X射线分辨率为133 eV）、Topaz-X高分辨率数字多道分析仪，以及牛津仪器公司100 W Neptune X射线管（采用铑（Rh）靶材）。数据采集分三轮开展，管电压分别设置为50 kV（第一轮）、30 kV（第二轮）与10 kV（第三轮）。原始数据的处理通过堪培拉尤里西斯（Canberra Eurisys）公司的迭代最小二乘软件包WIN AXIL对X射线能谱进行分析完成。
