Abstract The Archean era (4 to 2.5 billion years ago, Ga) yielded rocks that include the
oldest conclusive traces of life as well as many controversial occurrences. Carbonaceous …

Petroleum-bearing fluid inclusions are small encapsulations of oil and gas that offer an
invaluable opportunity to better constrain the evolution of petroleum systems. Insights into …

Construction and assembly of the Geologic Time Scale involves:(a) constructing a relative
(chronostratigraphic) standard scale for key periods in the Earth's rock record;(b) identifying …

Assembly of the supercontinent Columbia at about 1.85–1.90 Ga coincided with several
events that affected the entire earth. The oldest worldwide network of orogenic belts formed …

The evidence for macroscopic life during the Palaeoproterozoic era (2.5–1.6 Gyr ago) is
controversial,,,,. Except for the nearly 2-Gyr–old coil-shaped fossil Grypania spiralis,, which …

The Palaeoproterozoic era was a time of profound change in Earth evolution and
represented perhaps the first supercontinent cycle, from the amalgamation and dispersal of …

This study characterized the catalytic combustions and emissions of litchi peels as a function
of five catalysts as well as the effect of the best catalyst on the pyrolysis by-products. Na 2 …

Cores recovered during the Agouron Griqualand Drilling Project contain over 2500m of well-
preserved late Archean Transvaal Supergroup sediments, dating from ca. 2.67 to 2.46 Ga …

Sedimentary hydrocarbon remnants of eukaryotic C26–C30 sterols can be used to
reconstruct early algal evolution. Enhanced C29 sterol abundances provide algal cell …

Oil-bearing fluid inclusions occur in a ca. 2.45 Ga fluvial metaconglomerate of the Matinenda
Formation at Elliot Lake, Canada. The oil, most likely derived from the conformably overlying …
