Description

Abstract:

These data represent the OZMIN Oracle relational database containing geological and resource information for Australian mineral deposits. OZMIN has been compiled from published references and has been designed so that attribute information can be retrieved and analysed in relation to spatial data contained in geographic information systems. The national mineral deposits dataset contains data on over one thousand major and historically significant mineral deposits for 60 mineral commodities (including coal). Data available via mapping interfaces on the Geoscience Australia website are updated weekly whilst data available via download are a snapshot at the "Ending Date" of the current database entries.

Lineage:

The data within this dataset is derived directly from the corporate ORACLE OZMIN Mineral Deposits database.

An ASCII extraction of the Geoscience Australia ORACLE database is generated as ASCII comma-delimited files for each table that is part of or used by the OZMIN database. Only data that is part of the current release of OZMIN (Release 3 - October 2000) is included.

An MS ACCESS database format is also replicated from the ORACLE database and uses the same table structure. Only data that is part of the current release of OZMIN (Release 3 - October 2000) is included.

The spatial representation of this database in (ArcView and MapInfo format) is extracted and generated using ArcInfo GIS software to meet the published data standard within the Geoscience Australia data dictionary. The extraction of the spatial GIS datasets is done within ArcInfo using advanced AML code (ORACOV.AML) developed by Dmitar Butrovski, Geoscience Australia.

Positional accuracy:

Nominal Scale 1:100 000

OZMIN database geological and commodity information is derived from literature. Literature search and data input are supervised by an experienced economic geologist. Data is also reviewed by economic geologists with more specific knowledge of each deposit. The positional accuracy is therefore reasonably high but variable due to the variablity of source information. However subsequent rigorous checking of locational information by scientists provides an accurate as can be location for the deposit based on all available literature.

Attribute accuracy:

Generally high although it can be variable dependant on the source information. This information is made as scientifically accurate as is possible through thorough checking of all available literature.

Logical Consistency:

A geoscientist visually inspected the finished dataset to make sure the attributes were accurate and the data were consistent spatially with the quality-controlled database it was derived from. Tests are also carried out on these data for data completeness, correct spatial representation, attribute accuracy, logical consistency and correctness, and where appropriate for compliance with Geoscience Australia's GIS data dictionary.

Completeness:

The dataset coverage is complete for the whole of continental Australia.
