Involvement of microbial mats in early fossilization by decay delay and formation of impressions and replicas of vertebrates and invertebrates [PDF]

, 2016
Microbial mats have been hypothesized to improve the persistence and the preservation of organic remains during fossilization processes. We test this hypothesis with long-term experiments (up to 5.5 years) using invertebrate and vertebrate corpses.Once ...

CHARACTERISTICS AND ORIGIN OF THE DOLOSTONES OF THE EDIACARAN DENGYING FORMATION IN THE EASTERN SICHUAN BASIN, SOUTH CHINA

Carpathian Journal of Earth and Environmental Sciences, 2022
The Ediacaran Dengying Formation dolostones were the crucial carrier of the co-evolution between the biota and environment before the Cambrian Explosion and the solid mineral and petroleum resources. Based on the petrological and mineralogical analyses, the Dengying Formation at the Liaojiacao Section consists of micritic, fine-crystalline and medium ...

Ocean acidification in the aftermath of the Marinoan glaciation [PDF]

, 2014
Boron isotope patterns preserved in cap carbonates deposited in the aftermath of the younger Cryogenian (Marinoan, ca. 635 Ma) glaciation confirm a temporary ocean acidification event on the continental margin of the southern Congo craton, Namibia.

Separate Determination of Strontium and Barium Mass Fractions in Calcite and Dolomite in Carbonate Rocks by a Multi‐step Sequential Leaching Procedure

Geostandards and Geoanalytical Research, Volume 49, Issue 4, Page 751-769, December 2025.
Key Points A ten‐step sequential leaching procedure was applied to dissolve carbonate samples, with 10% of the sample mass dissolved in each step. Calcite dissolves preferentially compared with dolomite. Strontium and barium concentrations released in each step are proportional to the dissolved calcite‐to‐dolomite ratio.
