The Paleoproterozoic megascopic Stirling biota

Paleobiology, 2007
AbstractThe 2.0–1.8-billion-year-old Stirling Range Formation in southwestern Australia preserves the deposits of a siliciclastic shoreline formed under the influence of storms, longshore currents, and tidal currents. Sandstones contain a megascopic fossil biota represented by discoidal fossils similar to the EdiacaranAspidellaBillings, 1872, as well ...

A Paleoproterozoic A-type Rhyolite

Chinese Journal of Geochemistry, 1999
The rhyolites in the upper Luliang Group of Shanxi, China, are Paleoproterozoic weakly alkaline volcanic rocks. They are characterized by high SiO2, Na2O + K2O, Zr, Nb, Ga, Y and REE contents and large FeO* /MgO, Rb/Sr and Ga/Al ratios, and low CaO, Sr and Eu contents, and share much in common with the A-type granitic rocks.

A Paleoproterozoic ophiolitic mélange, Yangtze craton, South China: Evidence for Paleoproterozoic suturing and microcontinent amalgamation

Precambrian Research, 2017
Abstract We document for the first time the presence of a Paleoproterozoic ophiolitic melange in the Archean–Paleoproterozoic Kongling Complex in the northern Huangling Dome, Yangtze craton, South China. Detailed field mapping, petrographic, geochronological and geochemical studies reveal that the melange consists of a suite of amphibolite facies ...
