Sedimentology of silica granules and haematite in the 3.47 Ga Antarctic Creek Member, Mount Ada Basalt, Western Australia

open access: yesSedimentology, EarlyView.
ABSTRACT The Paleoarchean Antarctic Creek Member of the Mount Ada Basalt, Eastern Pilbara Terrane, Western Australia, includes beds of jasper and white chert composed of sand‐sized silica granules that often contain or are mixed with silt‐sized particles of haematite.

Emergence of Continents Stabilized the Bioavailability of Boron

open access: yesTerra Nova, EarlyView.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

Detrital zircon from a late Paleozoic accretionary complex of SW Iberia (Variscan Belt): History of crustal growth and recycling at the Rheic convergent margin [PDF]

open access: yes, 2012
In this study we present new U-Pb ages of detrital zircons from greywackes and quartzites of the Pulo do Lobo Anticline (PLA) that have been interpreted to represent a Late Paleozoic accretionary complex in SW Iberia.

THE RESULTS OF THE U/PB DATING OF DETRITAL ZIRCONS FROM THE PRECAMBRIAN AND PALEOZOIC SANDSTONES OF THE WESTERN PART OF BASHKIR UPLIFTS (THE SOUTHERN URALS)

open access: yesRUDN Journal of Engineering Research, 2015
There are the results of U-Pb dating of detrital zircons from the sandstones of the Bashkir uplift of the Southern Urals and the analysis of U-Pb-isotopic ages of detrital zircons from the six stratigraphic levels of the Riphean-Paleozoic section in the ...

Congo River sand and the equatorial quartz factory [PDF]

open access: yes, 2019
A never solved problem in sedimentary petrology is the origin of sandstone consisting exclusively of quartz and most durable heavy minerals. The Congo River offers an excellent test case to investigate under which tectonic, geomorphological, climatic ...

U/Pb Age of detrital zircons from sandstones of the upper emsian diamond takaty formation of the Western Urals

open access: yesRUDN Journal of Engineering Research, 2015
The first results of U/Pb (LA-ICP-MS) dating of detrital zircons from quartz sandstones of the Devonian Takaty Formation are presented. The obtained ages span a range from 1857.5 ± 53.8 to 3054.0 ± ± 48.0 Ma.
