The carbon emissions of large igneous province magmatism are commonly associated with severe environmental crises. We developed a technique that used sedimentary mercury records to estimate these carbon fluxes through time and found that they are smaller and/or slower than assumed, which suggests that the influence of carbon-cycle feedback processes is underestimated in current models.

早侏罗世大型火成岩省碳排放受到沉积汞的限制

大型火成岩省岩浆作用的碳排放通常与严重的环境危机有关。我们开发了一种技术，使用沉积汞记录来估计这些随时间变化的碳通量，发现它们比假设的更小和/或更慢，这表明当前模型低估了碳循环反馈过程的影响。
