Sequence of Events
A simplified sequence of events known from the Narryer Gneiss Terrane of the Western Gneiss Belt of the Yilgarn craton is reproduced after A. F. Trendall (1991);
- 2000-1600 Ma;
Basic dykes, related to the Gascoyne Complex and Capricorn Orogeny - 2700-2600 Ma;
Granite sheets and juxtaposition with the Yilgarn craton. - 3350-3300 Ma; Amphibolite to granulite facies metamorphism
- ~3350-3400 Ma; deposition of metasedimentary rocks
- 3400 Ma; Intrusion of syenogranites to form Dugel Gneiss, basic and ultramafic dykes
- >3400-3680 Ma; Deformation
- ~3680 Ma; Meeberrie Gneiss
- >3680-3730 Ma; Deformation
- ~3780 Ma; Manfred Complex ultramafic-mafic layered intrusion
- >4100 Ma; Metasedimentary precursor gneiss to host the Manfred Complex

Famous quotes containing the words sequence and/or events:
“We have defined a story as a narrative of events arranged in their time-sequence. A plot is also a narrative of events, the emphasis falling on causality. “The king died and then the queen died” is a story. “The king died, and then the queen died of grief” is a plot. The time sequence is preserved, but the sense of causality overshadows it.”
—E.M. (Edward Morgan)
“By the power elite, we refer to those political, economic, and military circles which as an intricate set of overlapping cliques share decisions having at least national consequences. In so far as national events are decided, the power elite are those who decide them.”
—C. Wright Mills (1916–1962)
