Extraterrestrial He in Sediments: From Recorder of Asteroid Collisions to Timekeeper of Global Environmental Changes
Most He in deep-sea sediments is derived from fine-grained extraterrestrial matter known as interplanetary dust particles (IDPs). These particles, typically\50 lm in diameter, are sufficiently small to retain solar windimplanted He with high He/He ratios during atmospheric entry heating. This extraterrestrial He (HeET) is retained in sediments for geologically long durations, having been detect...
متن کاملGeochemistry of the Paleocene Sediments from SW Ahar: Implications for Provenance, Tectonics and Source Rock Weathering
The mineralogy and geochemistry of Paleocene shales and interbedded siltstones in the southwestern of Ahar town (NW Iran) were studied by optical microscopy, XRD, SEM, XRF, and ICP-MS techniques. The mineralogical composition, mainly characterized by calcite, quartz, feldspar, dolomite, muscovite, magnesiohornblende, chlorite, illite, montmorionite, palygorskite, and koninckite, suggests relati...
متن کاملRecord bio-events and study the distribution of calcareous nannofossils in Cretaceous-Paleogene sediments, Neo-Tethys Ocean realm
In the present study, the sediments of the Gurpi Formation in the Jafarabad section located in the southeast of Ilam were examined from the point of view of calcareous calcareous nannofossils. The sediments of the upper part of Gurpi Formation with a thickness of about 42 m are composed of limy marl sediments. In this study, 34 species belonging to 22 genera from the group of calcareous nannopl...

متن کاملComparative mineralogical and geochemical clay sedimentation in the Betic Cordilleras and Basque-Cantabrian Basin areas at the Cretaceous-Tertiary boundary
The mineralogy and geochemistry of the bulk rock and clay fraction of sediments deposited at the CretaceousTertiary transition and in the KTB layer have been investigated by various methods in two sections from the Betic Cordilleras (Agost, Caravaca) and five sections from the Basque-Cantabrian Basin (Monte Urko, Sopelana, Zumaya, Hendaye, Biarritz). Active terrigenous supply prevailed in both ...
