Palynofacies, microcharcoal, clay mineralogical, and carbon isotope mass spectrometry measurements from the Late Pliensbachian interval (934–918 mbs) of the Mochras borehole in Wales. The dataset extends previously published data and covers the onset of a positive carbon-isotope excursion, collected and analyzed by researchers including Teuntje Hollaar and Stephen Hesselbo.
Use Cases
- Analyze the onset of the Late Pliensbachian positive carbon-isotope excursion using bulk organic carbon-isotope measurements.
- Correlate palynofacies and microcharcoal data with clay mineralogical data to interpret paleoenvironmental conditions.
- Integrate TOC and CaCO3 data with linked XRF datasets for multi-proxy stratigraphic analysis of the Upper Margaritatus Zone.
Strengths
- Dataset extends a previously published and peer-reviewed dataset (DOI: 10.5285/d6b7c567-49f0-44c7-a94c-e82fa17ff98e).
- Linked to a complementary XRF dataset (DOI: 10.5285/c09e9908-6a21-43a8-bc5a-944f9eb8b97e) covering the same study interval.
- Created within the scope of the funded JET project (NE/N018508/1) involving ICDP and NERC.
Limitations
- Specific row count, column names, and sample data are unavailable, limiting preliminary assessment of structure and volume.
- Data is confined to a single core (Mochras) and a narrow stratigraphic interval (16 meters), limiting geographic and temporal breadth.
