232 PDS DSV 1 This spreadsheet contains oxide abundance data derived from the APXS RDR products. The first record in the file gives the names of the fields in the following records. The remainder of the file consists of one record for each summed spectrum. Records are variable-length and fields are comma-delimited. 220 Carriage-Return Line-Feed Comma 37 0 "spectrum_id" 1 ASCII_String Name of the summed spectrum "spectrum_type" 2 ASCII_String Sample type, where SU = soil undisturbed SD = soil disturbed ST = Soil trench SC = Soils crest RU = Rock undisturbed RB = Rock brushed RR = Rock ratted C = Cobbles "sample_name" 3 ASCII_String Unofficial sample name "initial_sum" 4 ASCII_Integer Sum of the oxide weight percent before normalization to 100 % "integration_time" 5 ASCII_Real Spectrum measurement time "na2o" 6 ASCII_Real Derived weight percent for Na2O "na2o_error" 7 ASCII_Real Estimated error for Na2O "mgo" 8 ASCII_Real Derived weight percent for MgO "mgo_error" 9 ASCII_Real Estimated error for MgO "al2o3" 10 ASCII_Real Derived weight percent for Al2O3 "al2o3_error" 11 ASCII_Real Estimated error for Al2O3 "sio2" 12 ASCII_Real Derived weight percent for SiO2 "sio2_error" 13 ASCII_Real Estimated error for SiO2 "p2o5" 14 ASCII_Real Derived weight percent for P2O5 "p2o5_error" 15 ASCII_Real Estimated error for P2O5 "so3" 16 ASCII_Real Derived weight percent for SO3 "so3_error" 17 ASCII_Real Estimated error for SO3 "cl" 18 ASCII_Real Derived weight percent for Cl "cl_error" 19 ASCII_Real Estimated error for Cl "k2o" 20 ASCII_Real Derived weight percent for K2O "k2o_error" 21 ASCII_Real Estimated error for K2O "cao" 22 ASCII_Real Derived weight percent for CaO "cao_error" 23 ASCII_Real Estimated error for CaO "tio2" 24 ASCII_Real Derived weight percent for TiO2 "tio2_error" 25 ASCII_Real Estimated error for TiO2 "cr2o3" 26 ASCII_Real Derived weight percent for Cr2O3 "cr2o3_error" 27 ASCII_Real Estimated error for Cr2O3 "mno" 28 ASCII_Real Derived weight percent for MnO "mno_error" 29 ASCII_Real Estimated error for MnO "feo" 30 ASCII_Real Derived weight percent for FeO "feo_error" 31 ASCII_Real Estimated error for FeO "ni" 32 ASCII_Real Derived weight percent in ppm (ug/g) for Ni "ni_error" 33 ASCII_Real Estimated error for Ni "zn" 34 ASCII_Real Derived weight percent in ppm (ug/g) for Zn "zn_error" 35 ASCII_Real Estimated error for Zn "br" 36 ASCII_Real Derived weight percent in ppm (ug/g) for Br "br_error" 37 ASCII_Real Estimated error for Br apxs_oxides_mer2.lbl 0 PDS3 Original PDS3 label Carriage-Return Line-Feed
