Radiometric Dating of Young MORB Using the <sup>40</sup>Ar<sup>39</sup>Ar Incremental Heating Method
Determination of reliable crystallization ages by K-Ar methods for young (<1 Ma), fresh basalts from the seafloor has been frustrated by several effects. The small amounts of radiogenic 4øAr developed over these timescales in such 10w-K rocks are difficult to resolve from predominantly atmospheric 4øAr. An additional concern is that mantle-derived 4øAr may not be totally outgassed when magmas q...
متن کاملNew ¡sup¿40¡/sup¿Ar/¡sup¿39¡/sup¿Ar dating of the Grande Ronde lavas, Columbia River Basalts, USA: Implications for duration of flood basalt eruption episodes
Grande Ronde Basalt (GRB) lavas represent the most voluminous eruptive pulse of the Columbia River-Snake River-Yellowstone hotspot volcanism. With an estimated eruptive volume of 150,000 km, GRB lavas form at least 66% of the total volume of the Columbia River Basalt Group. New Ar/Ar dates for GRB lavas reveal they were emplaced within a maximum period of 0.42 ±0.18 My. A well-documented strati...
متن کاملK-Ar and Ar-Ar Dating
The aim of this chapter is to present the K-Ar and Ar-Ar dating techniques in the context of noble gas studies, since there are already several recent texts on K-Ar and ArAr dating (Dickin 1995; McDougall and Harrison 1999). The focus of this section will be aspects of argon transport and storage in the crust, which affect K-Ar and Ar-Ar dating including Ar-loss from minerals by diffusion and A...
متن کاملAr/Ar geochronology of the Eocene Green River Formation, Wyoming
The deposits of Eocene Lake Gosiute that constitute the Green River Formation of Wyoming contain numerous tuff beds that represent isochronous, correlatable stratigraphic markers. Tuff beds selected for Ar/Ar analysis occur within laminated mudstone, are matrix supported, and lack evidence of reworking. These tuffs contain 2%–15% euhedral phenocrysts of quartz, plagioclase, sanidine, biotite, a...
متن کاملInvestigation of UV/TiO2-N photocatalytic degradation of AR 40 using response surface methodology (RSM)
Introduction: Advanced oxidation processes (AOPs) suggest a highly reactive, nonspecific oxidant namely hydroxyl radical (OH•), that oxidize a wide range of pollutants fast and non-selective in wastewater and water. Materials and methods: In this work, the nitrogen-doped titanium dioxide nanoparticles were primed by sol-gel method, characterized by X-ray diffraction and Scanning Elect...
