Paleosols as indicators of paleoenvironment and paleoclimate
Paleosols are ancient soils that have been incorporated into the geological record. Soils
form in response to interactions among the lithosphere, hydrosphere, biosphere, and …

Calcretes
Calcretes (synonym: caliches) represent calcium-carbonate accumulations in a variety of
soils (and palaeosols) by pedogenic processes, as well as in surficial sediments in which …

Use of U–Pb ages of detrital zircons to infer maximum depositional ages of strata: a test against a Colorado Plateau Mesozoic database
WR Dickinson, GE Gehrels - Earth and Planetary Science Letters, 2009 - Elsevier
We test the research strategy of using youngest U–Pb ages of detrital zircons to constrain
the maximum depositional ages of strata containing the zircon grains by comparing U–Pb …

High-precision U-Pb zircon age from the Triassic of Italy: Implications for the Triassic time scale and the Carnian origin of calcareous nannoplankton and dinosaurs
The Triassic time scale is poorly constrained due to a paucity of high-precision radiometric
ages. We present a 206Pb/238U age of 230.91±0.33 Ma (error includes all known sources) …

A chronostratigraphic framework for the upper Stormberg Group: implications for the Triassic-Jurassic boundary in southern Africa
Abstract The upper Stormberg Group (Elliot and Clarens formations) of the main Karoo
Basin is well-known for its fossil vertebrate fauna, comprising early branching members of …

Directly dating geologic events: U‐Pb dating of carbonates
Carbonates are ubiquitous, forming in a variety of settings including caves, soils, the oceans,
during burial from hydrothermal fluids, and along faults. U‐Pb dating of carbonates is …

[HTML][HTML] U-Pb dating of calcite cement and diagenetic history in microporous carbonate reservoirs: Case of the Urgonian Limestone, France
Microporous carbonates can constitute excellent hydrocarbon reservoirs if their micropore
and/or nanopore structure is sufficiently developed and continuous. In such deposits …
