This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard is for persons who work or intend to work within a mining and minerals context.

Persons credited with this unit standard are able to:
  • Demonstrate an understanding of the physical properties of the Earth.
  • Demonstrate an understanding of the internal structure of the Earth.
  • Demonstrate an understanding of the units of time used in geology.
  • Demonstrate an understanding of the time required for geological processes.
  • Demonstrate an understanding of the time relationships of geological events in South Africa.

    The skills, knowledge and understanding demonstrated within this unit standard are essential for the social and economic transformation and contribute to the upliftment and economic growth of the mining and minerals sector.

    This unit standard is intended to promote general skills, knowledge and demonstrating an understanding of the Earth's Internal Structure and Age relative to the mining and minerals sector in order to ensure knowledgeable and informed workers.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
