Geochemical and isotopic data from glendonites and surrounding sediment, Carter Creek, North Slope Alaska

Metadata Updated: July 6, 2024

The dataset consists of geochemical and isotopic data from fine-grained sediments and glendonite crystals collected at Carter Creek on the North Slope of Alaska. Total Organic Carbon (TOC) values in the measured section were found to range between 0.5 and 3.5%, with a shift towards lower values in the uppermost 5 m of the section. Stable isotopes (13C) in organic matter were relatively stable throughout the section, ranging between -25.5 and -26, with a slight 0.3 per mil positive shift within this range approximately 57 m from the base of the section. Glendonites themselves were analyzed for d13Ccarb and d18Ocarb, with d18O values relatively consistent between -0.22 and +1.28, and a much wider range of d13C values between -15 and -44 per mil. 87Sr/86Sr isotope ratios from glendonite exteriors and and a bivalve fragment found in the section yielded values between 0.70819 and 0.70827, and dense, mineralized interiors were slightly higher at ~0.7084. Raman spectroscopic parameters (position and full width at half-maximum (FWHM) of the v1 calcite peak around 1087 cm-1) also varied internally within glendonite specimens, with the earliest phases of calcite (referred to as Types 1, 2A, and 2B) showing lower values in both measurements compared to later Type 3 calcite.
