Geology of Australia - Blocks

Blocks

The main continental blocks of the Australian continent are;

  • The Yilgarn Craton, of Archaean age
  • The Pilbara Craton of Archaean to Proterozoic age
  • The Gawler Craton and Willyama Block, of Archaean to Proterozoic age.

These are in turn flanked by several Proterozoic orogenic belts and sedimentary basins, notably the

  • Musgrave Block of granulite gneiss and igneous rocks
  • The Arunta Block of amphibolite grade metamorphic rocks and granites
  • The Gascoyne Complex, Glengarry Basin, and Bangemall Basin sandwiched between the Yilgarn and Arunta Blocks

Famous quotes containing the word blocks:

    “Good blocks of oak it was I split,
    As large around as the chopping block;
    And every piece I squarely hit
    Fell splinterless as a cloven rock.”
    —Robert Frost (1874–1963)

    “The quest for certainty blocks the search for meaning. Uncertainty is the very condition to impel man to unfold his powers.”
    —Erich Fromm (1900–1980)

    “The vast silence of Buddha overtakes
    and overrules the oncoming roar
    of tragic life that fills alleys and avenues;
    it blocks the way of pedicabs, police, convoys.”
    —Denise Levertov (b. 1923)
