Quantum mechanics imposes limits on measurement accuracy.through quantum noise which ty.ically.has two components: First is the shot noise originating from vacuum fluctuations and referred to as the imprecision noise. Second is the quantum back.ction originating from the “action” of the measurement back.on the object being measured.

The oxidative weathering of petrogenic organic carbon(OC_(petro)) is an important source of carbon dioxide(CO_(2)) into the atmosphere on geological timescales and significantly.influences the carbon cy.le and global climate change. However, at present, a robust proxy.to assess OC_(petro)oxidation is lack.ng. Riverine rhenium(Re) has emerged as a potential proxy.to trace OC_(petro)oxidation, but little is k.own about Re sources and its relationship with OC_(petro)oxidation. To better understand the robustness of this proxy. we analy.ed a shale weathering profile from the early.Cambrian Shuijingtuo Formation in Chengk.u County. Chongqing City. to address the mobility.of Re and selenium(Se) and their relationship with the oxidation of OC_(petro)by.analy.es of the elemental variation and sequential extraction. The results showed that the chemical index of alteration(CIA)increases from the fresh bedrock.to the weathered sections, indicating enhanced weathering intensity. Based on the sequential extraction and mass transfer coefficients(τ), Re and Se mainly.exist in the organic phase of shale and are paired lost with OC_(petro) during weathering, with no obvious correlation with sulfide minerals. Furthermore, the different proportions of Re and Se loss with OC_(petro) loss can be attributed to their different geochemical behaviors during weathering. Our study.supports Re as a robust proxy.to trace OC_(petro) oxidation, whereas Se is the potential one. In the future, combined studies on various sedimentary.rock.profiles with catchment basins are needed to determine the sources of riverine Re and Se and their relationships with OC_(petro) oxidation.
