- Abstract:
-
In the summers of 2004, 2005, 2006, and 2008, the U.S. Geological Survey (USGS) conducted a reconnaissance geochemical survey of the drainage basins throughout the Taylor Mountains 1:250,000-scale quadrangle, in southwestern Alaska. The purpose of this study is to provide data for concurrent USGS geologic mapping and mineral resource assessment efforts, to provide data that may be used to determine regional-scale element baselines, and to identify areas of potential interest for ore minerals. This report provides the stream-sediment sample analytical data for the study.
- Purpose:
-
These data may be useful to locate areas of potential interest for ore minerals, to provide data that may be used to determine regional-scale element baselines, and to provide data that may be helpful for mineral resource assessment studies.

Version 1.1
1) Data for 96 stream-sediment samples collected in 2008 were added to data table 1.
2) Data for 24 rock samples collected in 2008 were added to data table 3.
3) The image file (OFR2007-1196_v1.1_fig.2.pdf) showing locations of sample collected was updated to include the locations for all samples collected in 2008.
4) Gold values determined by atomic absorption spectrophotometry after collection by fire assay (Au_FA/AA in table 1) in the stream-sediment samples collected by the USGS in 2004 were converted TO ppb (parts per billion) FROM ppm (parts per million).
5) The lower reporting limit for Cs (cesium) measured by the 42-element multi-acid digestion inductively coupled plasma-atomic emission spectrometry or inductively coupled plasma-mass spectrometry method (Cs_ICP42 ppm in table 1) was changed by the USGS contract laboratory in 2006 TO 5 ppm FROM 0.05 ppm. All results for Cs determined by this method in stream-sediment samples collected in 2004 and in 2005 were changed to reflect the revised lower reporting limit of 5 ppm. Values previously reported in data table 1 in version 1.0 of this report that were less than 5 ppm have been changed to <5 in data table 1 in version 1.1.
6) Web-only references for the analytical methods used by the USGS contract laboratory were added to the downloadable report and the metadata.
7) OpenDocument Spreadsheet (ODS) and MS Excel 2007 (XLSX) versions of the data tables were added.
8) An XML version of the metadata was added.

These tables contain data for 848 stream-sediment samples and 59 rock samples collected in the Taylor Mountains 1:250,000-scale quadrangle, Alaska. The fields (columns) consist of sample identification, location, descriptive, and analytical information about each sample. The location and descriptive information was recorded in the field at the time of collection by the sample collector. These samples were analyzed for Au, Pt, and Pd by fire assay with inductively coupled plasma-mass spectrometry finish (FA/ICP-MS); for As by hydride generation-atomic absorption spectrometry (HGAAS); for Hg by cold vapor-atomic absorption spectrometry (CVAAS); for 10 potentially ore-related metals by inductively coupled plasma-atomic emission spectrometry (ICP-AES) following partial digestion and extraction into organic solution; and for 42 elements by inductively coupled plasma-atomic emission spectrometry or inductively coupled plasma-mass spectrometry (ICP-AES-MS) following a multi-acid digestion. Some samples collected in 2004 were analyzed for gold by atomic absorption spectrophotometry after fire assay collection (FA/AA).

Character data without scientific significance. Each value assigned by the submitter is unique. The first 2 characters represent the year the sample was collected. The next 2 characters represent the 1:250,000-scale quadrangle the sample was collected in. In this case TA = Taylor Mountains. The next 3 or 4 characters represent the site number assigned by the collector. The last character represents the sample media. For this report, S = sediment and R = rock. A 'D' following the sample media character means the sample is a site duplicate. If a number or letter follows the sample media character it means that more than one unique sample was collected at the site. This is seen most commonly in the rock data set. Field numbers that begin with a 'B' were collected in 2004 by Bristol Bay Native Corporation personnel under a Cooperative Research and Development Agreement (CRADA) with the USGS. These samples were collected using USGS sampling protocol and were prepared and analyzed by the USGS.

Depending on the type of sample, there may be a significant discrepancy between the proposed value and the laboratory value. This is primarily due to the availability of the metal in the sample. Since this is a partial digestion, those metals tightly bound in highly resistant minerals will not be extracted. Data will be deemed acceptable if recovery for all 10 elements is +/-20% on spikes at five times the LOD and the calculated percent RSD of duplicate samples is no greater than 20%.

- Attribute_Label: Cd_ICP10_P ppm
- Attribute_Definition:
-
Concentration of cadmium in stream-sediment samples; determined by a partial extraction technique (Aliquat/MIBK) modified and adapted for use with inductively coupled plasma-atomic emission spectrometry for the analysis of geologic materials. It is important to note that this procedure is a partial digestion and depending on an element availability, results may be biased low when compared to other methods of analyses. Reported in ppm (parts per million).

The location and descriptive information was recorded in the field at the time of collection by the sample collector. These samples were analyzed by inductively coupled plasma-atomic emission spectrometry or inductively coupled plasma-mass spectrometry (ICP-AES-MS) following sodium peroxide sinter at 450 degrees Celsius.

Character data without scientific significance. Each value assigned by the submitter is unique. The first 2 characters represent the year the sample was collected. The second 2 characters represent the 1:250,000-scale quadrangle the sample was collected in. In this case TA = Taylor Mountains. The next 3 or 4 characters represent the site number assigned by the collector. The last character represents the sample media. For this report, S = sediment and R = rock. A 'D' following the sample media character means the sample is a site duplicate. If a number follows the sample media character it means more than one unique sample was collected at the site. This is seen most commonly in the rock data set. Field numbers that begin with a 'B' were collected in 2004 by Bristol Bay Native Corporation personnel under a Cooperative Research and Development Agreement (CRADA) with the USGS. These samples were collected using USGS sampling protocol and were prepared and analyzed by the USGS.

This table contains data for 59 rock samples collected in the Taylor Mountains 1:250,000-scale quadrangle. The fields (columns) consist of sample identification, location, descriptive, and analytical information about each sample. The location and descriptive information was recorded in the field at the time of collection by the sample collector. These samples were analyzed for Au, Pt, and Pd by fire assay with inductively coupled plasma-mass spectrometry finish (FA/ICP-MS); for As by hydride generation-atomic absorption spectrometry (HGAAS); for Hg by cold vapor-atomic absorption spectrometry (CVAAS); for 10 potentially ore-related metals by inductively coupled plasma-atomic emission spectrometry (ICP-AES) following partial digestion and extraction into organic solution; and for 55 elements by inductively coupled plasma-atomic emission spectrometry or inductively coupled plasma-mass spectrometry (ICP-AES-MS) following sodium peroxide sinter at 450 degrees Celsius.

Character data without scientific significance. Each value assigned by the submitter is unique. The first 2 characters represent the year the sample was collected. The second 2 characters represent the 1:250,000-scale quadrangle the sample was collected in. In this case TA = Taylor Mountains. The next 3 or 4 characters represent the site number assigned by the collector. The last character represents the sample media. For this report, S = sediment and R = rock. A 'D' following the sample media character means the sample is a site duplicate. If a number or a letter other than 'D' follows the sample media character it means more than one unique sample was collected at the site. This is seen most commonly in the rock data set.
