X-ray fluorescence (XRF) data of sediment core GeoB24351-1, 50 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).

X射线荧光（XRF）扫描针对岩芯GeoB24351-1（格连吉克MV；0~284 cm）开展，实验于不来梅的MARUM——海洋环境科学中心完成，采用XRF岩芯扫描仪III（AVAATECH，序列号12），在存档半岩芯的劈开面上以10 mm步长沿岩芯向下扫描。为避免XRF测量单元受到污染以及沉积物脱水，劈开的岩芯表面覆盖了一层厚度为4 µm的SPEXCerti Ultralene1箔膜。本次报告所用数据由以下设备采集：SGX Sensortech公司的硅漂移探测器（型号Modul S SiriusD®D65133Be-INF，X射线分辨率达133 eV）、Topaz-X高分辨率数字化多道分析仪（MCA），以及牛津仪器公司的100 W Neptune X射线管（靶材为铑（Rh））。数据分三次扫描获取，分别采用50 kV（第一次扫描）、30 kV（第二次扫描）和10 kV（第三次扫描）的工作电压。原始数据的处理采用Canberra Eurisys公司的WIN AXIL迭代最小二乘软件包完成，通过该软件对X射线能谱进行分析。
