摘要:Zero deforestation commitments (ZDCs are voluntary initiatives where companies or countries pledge to eliminate deforestation from their supply chains. These commitments offer much promise for sustainable commodity production, but are undermined by a lack of transparency about th...

摘要:Abstract(#br)Paleomagnetic studies of meteorites have shown that the solar nebula was likely magnetized and that many early planetary bodies generated dynamo magnetic fields in their advecting metallic cores. The surface fields on these bodies were recorded by a diversity of...

摘要:To date, assessments of the sustainability of agricultural commodity supply chains have largely relied on some combination of macro-scale footprint accounts, detailed life-cycle analyses and fine-scale traceability systems. Yet these approaches are limited in their ability to sup...

摘要:Abstract(#br)In order to identify the parent bodies of cosmic spherules (melted micrometeorites) with porphyritic olivine (PO) and cryptocrystalline (CC) textures, we measured the oxygen isotopic composition of 15 giant (>800 μm) cosmic spherules recovered in the Transantarc...

摘要:Abstract(#br)Oxygen isotopic compositions allow identification of potential parent bodies of extraterrestrial materials. We measured oxygen isotope ratios of 33 large (diameter > 500 μm) silicate melted micrometeorites (cosmic spherules) from Antarctica, using IR-laser fluor...

摘要:Abstract(#br)Eleven large (∼400–700 μm in diameter) differentiated glass cosmic spherules were identified from the Transantarctic Mountain micrometeorite collection on the basis of their high Fe/Mg ratios (from 0.6 to 1.6) and their homogeneous Fe/Mn ratios (31 ± 4). Th...

摘要:Abstract(#br)Recent analyses of Apollo samples have demonstrated that a core dynamo existed on the Moon between at least 4.25 and 3.56 billion years ago (Ga) with surface field intensities reaching ∼70 μT. However, it is unknown when the Moon's magnetic field declined. Deter...

摘要:Abstract(#br)New geochemical data on cosmic spherules (187 major element, 76 trace element, and 10 oxygen isotope compositions) and 273 analyses from the literature were used to assess the chemical diversity observed among glass cosmic spherules with chondritic composition. ...

摘要:Abstract(#br)We describe a system for conducting thermal demagnetization of extraterrestrial rocks in a controlled atmosphere appropriate for a wide range of oxygen fugacities within the stability domain of iron. Thermal demagnetization and Thellier‐Thellier paleointensity e...

摘要:Abstract(#br)Micrometeorites have been recovered from traps located at the summit of nunataks in the Transantarctic Mountains (TAM), Antarctica. They constitute the TAM micrometeorite collection. Micrometeorites accumulated by direct infall for hundreds of thousands of years...
