Paleoenvironmental Evolution Characteristics and Mineral Enrichment Patterns of the Lacustrine System Under Orbital Forcing in the Yin'e Basin During the Early Cretaceous

Description

he samples cover the entire first member of the Bayingebi Formation (total thickness: 189 m). Specific grouping: 26 samples were prepared as thin sections for microscopic and scanning electron microscope (SEM) observations; 71 samples were analyzed for mineral composition using X-ray diffraction (XRD); 51 mudstone and marlstone samples were selected for determinations of total organic carbon (TOC), organic carbon isotope (δ¹³C), and nitrogen isotope (δ¹⁵N); while 20 high-organic-content mudstone samples were used for biomarker analysis via gas chromatography-mass spectrometry (GC-MS); and 369 samples were subjected to chromaticity and magnetic susceptibility (MS) measurements.
