This project aims to deliver mineral occurrence data through the Australian Geoscience Portal, enabling data transfer between organizations, developing standard data models and vocabularies for better interoperability. The system will use GeoSciML and extensions based on international standards to classify real-world objects.

  1. The Australian mineral occurrence data model Adele Seymon for the TEAM…

  2. GGIC Mineral Occurrence working group

  3. Why? • Deliver data through the Australian Geoscience Portal - RELEVANT TO YOU, THE EXPLORERS! • How? • Permitdata transfer between organisations • Develop a standard data model • Develop standard vocabularies

  4. interoperability Current ‘Systems’ Semantic(Data Content) Few standards Schematic(Data Structure) Organisation specific Syntax(Data Language) Access, Excel,Proprietary GIS Systems(Data Services) Files, DVD, CD What? GeoSciML System Controlled Vocabularies Mineral Occurrences, GeoSciML, O&M GML, XML WFS, WMS, WCS

  5. How? • Extension of GeoSciML • Based on other international standards • Real-world objects classified into types based on a characteristic set of properties

  6. Mineral Occurrence Mineral System Mapped Feature Earth Resource Material Mineral Deposit Model e.g. komatiite hosted nickel Ore Measure Resource Reserve Endowment Commodity Mine Product Mining Activity

  14. Key points • Describes Mineral Occurrences independent of human activities • NiS mineral occurrence • Caters for description of Min Occ using: • Mineral Deposit Models (e.g. remobilised NiS) • Mineral Systems (Geodynamic context) • Crustal processes • Requires use of controlled vocabularies

  15. Key points cont. • Utilises GeoSciML Mapped Feature to describe spatial representation • Utilises GeoSciML Earth Material to describe host and associated materials

  16. Controlled vocabularies – examples • Deposit expression (e.g. Gossan, mag high, gravity low) • Deposit shape and form (e.g. stratabound)

  19. Controlled vocabularies – more examples • Measurement categories (i.e. grade, tonnage) • MiningActivityCodeList (e.g. Open pit/underground) • MineStatusCodeList (e.g. Operating, abandoned)

  20. Future work • Model needs theMineral Systems part developed • Source: melt composition, physical properties, metal endowment • Pathways: propagation, complexity, flow regime • Traps: efficiency, periodicity, scale

  21. Future work and limitations • 6 of 7 surveys have mapped their databases to the Mineral Occurrence domain model • Awaiting development of software to allow delivery • Industry and software vendors need to adopt
