Analytical results from lightning discharge experiments focusing on interactions between nitrogen oxides and pyrite
The dataset includes measurements of dissolved and gaseous nitrogen oxides (nitrite, nitrate, NO(g)) generated by lightning discharge in a glass container partially filled with water, as well as measurements of dissolves sulfate and iron liberated from pyrite that has interacted with the nitrogen oxides. The lightning discharge experiments were carried out with either anoxic gas mixture (5% or 20% CO2 and the rest N2) or modern air. Lightning has long been identified as a source of reactive nitrogen species to Earth's early biosphere. These experiments were therefore conducted in order to test how this reactive nitrogen would interact with minerals at the Earth's surface. The results reveal that lightning-generated nitrogen oxides could have contributed to a small degree to oxidative weathering.

- Statement
- The experimental setup was similar to that of Barth et al. (2023, Nature Geoscience). Pyrite was added to the reaction flask, along with 21ml of deoxygenated DI-water. Nitrite, nitrate and nitric oxide gas, as well as sulfate and iron were measured over time by extracting 3ml of liquid every 6 minutes with a syringe through a septum. The analyses were conduced with an ion chromatograph for nitrite, nitrate and sulfate. Iron was measured by spectrophotometry. Nitric oxide gas was measured with an quadrupole mass spectrometer. Analytical details are described in Long et al. (in review). The aqueous data were corrected for the volume change that occurred as fluid was extracted. All experiments were carried out in triplicates. Blank experiments were conducted where the spark generator was turned off.
