Mineral composition of altered felsic volcanic rocks from ODP Site 193-1188 and Hole 193-1189A, PACMANUS field@en

This report presents short-wave infrared spectroscopic data acquired from both core and powdered samples collected during Ocean Drilling Program Leg 193, from Holes 1188A, 1188F, and 1189A, using a Portable Infrared Mineral Analyzer reflectance spectrometer. The distribution of alteration minerals detected using this method for each site is presented.本报告展示了借助便携式红外矿物分析仪（Portable Infrared Mineral Analyzer）反射光谱仪，对大洋钻探计划（Ocean Drilling Program, ODP）第193航次中1188A、1188F及1189A三个钻孔采集的岩心与粉末样品所测得的短波红外（short-wave infrared, SWIR）光谱数据；同时呈现了采用该方法在各钻探位点检测到的蚀变矿物分布情况。
