Musgrave Block

The Musgrave Block (also known as the Musgrave Province) is an east-west trending belt of Proterozoic granulite-gneiss basement rocks approximately 500 km long. The Musgrave Block extends from western South Australia into Western Australia.

The Musgrave Block is primarily exposed through the actions of the Petermann Orogeny at c. 535-550 Ma, which exhumed the orogenic belt along the Woodroffe Thrust.

Famous quotes containing the words block and/or musgrave:

    Dug from the tomb of taste-refining time,
    Each form is exquisite, each block sublime.
    Or good, or bad,—disfigur’d, or deprav’d,—
    All art, is at its resurrection sav’d;
    All crown’d with glory in the critic’s heav’n,
    Each merit magnified, each fault forgiven.
    Martin Archer, Sir Shee (1769–1850)
