| Inhoud: |
The Arunta Inlier is a 200 000 km2 region of mainly Precambrian metamorphosed sedimentary and igneous rock in central Australia. To the N it merges with similar rocks of lower metamorphic grade in the Tennant Creek Inlier, and to the NW it merges with schist and gneiss of The Granites-Tanami Province. It is characterized by mafic and felsic meta-igneous rocks, abundant silicic and aluminous metasediments and carbonate, and low- to medium-pressure metamorphism. Hence, the Arunta Inlier is interpreted as a Proterozoic ensialic mobile belt floored by continental crust. The belt evolved over about 1500 Ma, and began with mafic and felsic volcanism and mafic intrusion in a latitudinal rift, followed by shale and limestone deposition, deformation, metamorphism and emergence. Flysch sedimentation and volcanism then continued in geosynclinal troughs flanking the ridge of meta-igneous rocks, and were followed by platform deposition of thin shallow-marine sediments, further deformation, and episodes of metamorphism and granite intrusion. |
