Description

Abstract:

This product is the single largest Geoscience Australia funded stream sediment geochemical data set available in Australia. The data covers roughly 80 000 square kilometres of Proterozoic and Phanerozoic north Queensland and contains 235 914 analyses of 8752 samples. This product also includes PDF files of the associated reports and atlases.

Data quality

Lineage:

The sediment samples were collect by BMR/AGSO field parties 1972-93 by vehicle or helicopter traverse. Samples were sieved at base camp (1972-80) or on site (1990-3) with -180 micron (1972-93) and -1mn (1990-3) fractions collected. Samples were analysed in BMR/AGSO laboratories by x-ray fluorescence spectrometry (XRFS) and atomic absorption spectrophotometry (AAS) (1972-93), and by inductively coupled plasma-mass spectrometry (ICP-MS, Analbs, Perth, 1990-3) and bulk cyanide leach for Au (BLEG, ALS, Brisbane, 1990-3). Navigation within the field was by air photo overlays (1972-80) and by GPS (1990-3). Samples sites were translated to the then current 1:100k maps and digitised.

Positional accuracy:

Some ground errors in the maps of up to 300-400m in positioning of major creeks was indicated by the usage of GPS. Sites were plotted onto maps as is, to ensure that samples were located along stream courses. A list of the maps and map editions used 1991-3 are included in the 3 records. The positional accuracy, along a stream course would be within 200 meters.

Attribute accuracy:

Samples were analysed by similar but evolving methodologies (XRFS and AAS) over the 20 year period in the same laboratory by essentially the same analysts. External analyses (1990-3) by Analbs and ALS are supposed to be by the same methodologies. Secondary standards and duplicates were run with sample batches to maintain a high degree of data accuracy.

Logical Consistency:

Not Relevant

Completeness:

Data coverage is for most of the area mapped. Some areas were missed due to time and access constraints. Areas immediately adjacent to major watercourses could not be sampled.
