Province of British Columbia Ministry of Energy, Mines and Petroleum Resources Mineral Resources Division Geological Survey Branch Environmental Geology Section File: FORMAT.DOC Date: August 4, 1993 FORMAT SPECIFICATION - REGIONAL GEOCHEMICAL SURVEY (RGS) DATA BC RGS 37 - NTS 104M Skagway ... This document describes the data format for recorded field observations and analytical data, with an explanation of the codes for the field observations. PLEASE NOTE: 1. Data for each sample are listed on single, fixed length lines. 2. The data format described in this document represents the most recent (August,1993) version. Missing field data are listed as a blank and missing analytical data are listed as -1. Please note that U, W, Sn and Cr by AAS and Zr by INAA were not included as part on the 1993 analytical suite of elements and are listed as -1. 3. The listed UTM sample site coordinates for map sheet 104M were digitized from the original 1:50 000 scale sample location field maps. ***** FIELD DATA ***** FIELD DESCRIPTION COLUMNS TYPE LENGTH EXAMPLE 01 NTS Map-Sheet 001-006 A 6 104M13 02 ID (Year,Crew,Number) 007-012 N 6 921102 03 UTM Zone 013-014 N 2 10 04 UTM East (Metres) 015-020 N 6 296410 05 UTM North (Metres) 021-027 N 7 5433351 06 Elevation (Metres) 028-031 N 4 1500 07 Sample Material 032 N 1 6 08 Replicate Status 033-034 N 2 10 09 Formation 035-038 A 4 EKgd 10 Source of Water 039 N 1 2 11 Stream Order 040 N 1 1 12 Stream Type 041 N 1 2 13 Physiography 042 N 1 3 14 Drainage Pattern 043 N 1 2 15 Contamination 044 N 1 3 16 Stream Width (metres) 045-048 N 4 (1) 10.5 17 Stream Depth (cm) 049-051 N 3 220 18 Stream Flow Rate 052 N 1 1 19 Water Colour 053 N 1 3 20 Bank Type 054 N 1 3 21 Bank Precipitate 055 N 1 2 22 Sediment Composition 056-058 N 3 111 23 Sediment Colour 059 N 1 5 24 Sediment Precipitate 060 N 1 2 25 Channel Bed Type 061 N 1 3 26 Channel Pattern 062 N 1 4 27 Date (day/month) 063-066 N 4 2510 ***** ANALYTICAL DATA ***** FIELD DESCRIPTION COLUMNS TYPE LENGTH EXAMPLE 28 pH of stream waters 067-072 N 6 (1) 7.0 29 Uranium in waters (ppb) 073-078 N 6 (2) 0.12 30 Fluoride in waters(ppb) 079-084 N 6 34 31 Sulphate in waters(ppm) 085-090 N 6 (1) 12.4 32 Zinc (ppm) 091-096 N 6 47 33 Copper (ppm) 097-102 N 6 79 34 Lead (ppm) 103-108 N 6 12 35 Nickel (ppm) 109-114 N 6 26 36 Cobalt (ppm) 115-120 N 6 33 37 Silver (ppm) 121-126 N 6 (1) 1.7 38 Manganese (ppm) 127-132 N 6 310 39 Iron (%) 133-138 N 6 (2) 3.80 40 Molybdenum (ppm) 139-144 N 6 10 41 Uranium (ppm) 145-150 N 6 (1) 4.5 42 Tungsten (ppm) 151-156 N 6 6 43 Tin (ppm) 157-162 N 6 5 44 Mercury (ppb) 163-168 N 6 30 45 Arsenic (ppm) 169-174 N 6 (1) 14.5 46 Antimony (ppm) 175-180 N 6 (1) 0.3 47 Cadmium (ppm) 181-186 N 6 (1) 0.7 48 Vanadium (ppm) 187-192 N 6 7 49 Bismuth (ppm) 193-198 N 6 (1) 0.6 50 Chromium (ppm) 199-204 N 6 88 51 LOI (%) 205-210 N 6 (1) 8.3 52 Fluorine (ppm) 211-216 N 6 400 **** INAA DATA **** 53 Gold(1st analysis)(ppb) 217-222 N 6 78 54 Gold (Repeat) (ppb) 223-228 N 6 200 55 Antimony (ppm) 229-234 N 6 (1) 1.7 56 Arsenic (ppm) 235-240 N 6 (1) 8.9 57 Barium (ppm) 241-246 N 6 850 58 Bromine (ppm) 247-252 N 6 (1) 29.5 59 Cerium (ppm) 253-258 N 6 18 60 Cesium (ppm) 259-264 N 6 6 61 Chromium (ppm) 265-270 N 6 36 62 Cobalt (ppm) 271-276 N 6 14 63 Hafnium (ppm) 277-282 N 6 12 64 Iron (%) 283-288 N 6 (2) 7.57 65 Lanthanum (ppm) 289-294 N 6 11 66 Lutetium (ppm) 295-300 N 6 (2) 0.65 67 Molybdenum (ppm) 301-306 N 6 10 68 Nickel (ppm) 307-312 N 6 39 69 Rubidium (ppm) 313-318 N 6 110 70 Samarium (ppm) 319-324 N 6 (1) 8.2 71 Scandium (ppm) 325-330 N 6 (1) 20.5 72 Sodium (%) 331-336 N 6 (2) 3.24 73 Tantalum (ppm) 337-342 N 6 (1) 1.9 74 Terbium (ppm) 343-348 N 6 (1) 0.8 75 Thorium (ppm) 349-354 N 6 (1) 7.6 76 Tungsten (ppm) 355-360 N 6 12 77 Uranium (ppm) 361-366 N 6 (1) 28.5 78 Ytterbium (ppm) 367-372 N 6 (1) 21.3 79 Zirconium (ppm) 373-378 N 6 560 80 Sample Weight (g) 379-384 N 6 (2) 19.35 Significant digit/s for data variables listed in brackets.
