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 ...

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.

Biostratigraphy and correlation of the Cambrian Series 2 (Stage 4) to Miaolingian (Wuliuan) Thorntonia Limestone, south‐eastern Georgina Basin (Queensland, Australia)

Papers in Palaeontology, Volume 11, Issue 5, September/October 2025.
Abstract The Australian Cambrian stratigraphic record is one of the most complete for any continent. However, there is a general division, with older Cambrian rocks in South Australia (predominantly Terreneuvian, Stage 2 to Miaolingian, Wuliuan) and younger rocks in northern Australia (mostly latest Series 2, Stage 4 and younger), with minimal ...
