Overcoming Polyatomic Interferences in Sulfur Isotope Measurement Using MC‐ICP‐MS

Geostandards and Geoanalytical Research, EarlyView.
Key Points Optimising plasma conditions via the normalised argon index (NAI) reduces polyatomic interferences, allowing accurate sulfur isotope measurement in low‐resolution mode on MC‐ICP‐MS. Low‐resolution mode enhances sensitivity by approximately threefold compared with conventional high‐resolution analysis.

Stable isotope data indicate origins of mislabelled historical bird specimens

Ibis, EarlyView.
Natural history specimens provide valuable insights across diverse research fields, but those needing more accurate metadata have limited scientific value. We applied stable isotope analysis to investigate the origin of 19th century Atlantic Forest bird specimens attributed to the northeastern Brazilian state of Pernambuco, which are the only records ...

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Geochemical and Seismic Constraints on the Role of Mud Diapirs in Petroleum Migration and Accumulation in the Recôncavo Basin, NE Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT In the Recôncavo Basin, Northeast of Brazil, mud diapirs have been reported for decades, but their role within the basin's petroleum system remains poorly constrained. Here, we combine 2D seismic interpretation, field observations, and organic geochemical analyses of rocks and oil seeps to investigate the relationship between diapirism and ...
