Description

Abstract:

Mapping of solid geology on Mt Keith 3043 1:100 000 map sheet in the

Eastern Goldfields, Western Australia, undertaken 1998 by A.J.Stewart

as part of the National Geoscience Mapping Accord (NGMA).

Briefly, mapping consists of geological boundaries/units, faults, folds,

veins, dykes, joints, linears, marker beds, trends, structural

measurements, drill holes and mineral deposits.

Data quality

Lineage:

Geological and geophysical themes were generated from field observations

and interpretation using aerial photographs (1:25 0000 colour),

and magnetic data (90m cell size grids derived from airborne magnetic surveys).

Geological mapping and other geological information obtained from industry,

and state/Australian Government bodies are incorporated. Mineral deposit

locations and information is largely sourced from GSWA Report 63.

Topographic themes have been provided by AUSLIG and DOLA with agreement

that public release of any topographic data by AGSO will be in non digital

form only. Some amendments to the topographic data have been made by the

authors. Lineage of topographic data, prior to receipt from AUSLIG and DOLA,

is uncertain. Maps were compiled from unrectified photo overlays onto

topographic bases supplied by AUSLIG and DOLA (see notes on topographic

data above). Drainage and, where necessary, other topographic features

(eg fence lines) were used for spatial control of the geological data.

Compilations were digitally captured either by hand or automatically by

scanning and vectorising procedures. Point data with database origins have

been located largely by non-differential GPS. Some detail may have been

generalised, repositioned, or omitted from the primary data for cartographic

purposes.

Positional accuracy:

The most prominent horizontal positional inaccuracy in this dataset has been

introduced during compilation to topographic base maps, and is estimated at

up to 300m. The main source of error is inaccuracies in the location of

topographic features on the base maps, which is compounded by insufficient

topographic features in some areas of the base maps with which to accurately

align the photo overlays. Positional errors generated by distortions in the

aerial photos and errors during the data capture process are difficult to

quantify and are believed to be negligible in comparison to the topo base

error.

GPS located features, such as structural measurements, have an error of up

to 100m due to selective availability imposed on GPS readings. The MINLOC

data has been found to have errors of up to several kilometres, and efforts

have been made by AGSO geologists during map production to correct the errors

using GPS, and/or aerial photos and topographic base maps as a spatial control.

Attribute accuracy:

The bulk of attributes in this data set are qualitative and quantitative

geological observations and measurements. Classifications of lithology and

linear geological features are largely interpretative, based on conventional

mapping techniques (field observations, photo/imagery interpretation, sample

collection and analysis), and adhere to well established and standardised

classification schemes. Structural measurements are quantitative, measured

using standard field mapping instruments.

Logical Consistency:

Rigorous quality control has ensured consistency in data structures and

standards across the dataset.

Revisional mapping on many of the earlier mapped sheets has been carried out

to achieve consistency in geological classifications across the dataset.

Completeness:

The level of work undertaken to map the project area used the Mount Keith

1:100 000 outcrop geology map supplemented by interpretation of magnetic data

and by detailed exploration company mapping.

Reliability diagrams are included with each hardcopy release of a map sheet.
