增强岩石风化（ERW）是一种基于用破碎的富含钙和镁的硅酸盐矿物修复土壤的技术，具有巨大的二氧化碳去除潜力。评价这些矿物的现有资源和目前的生产能力对于在早期部署这种办法至关重要。为了确保ERW的可伸缩性，还需要对利用这些资源的潜在限制有充分的了解。本文提供了英国基性硅酸盐岩石资源的空间清单，以及目前的生产能力和允许储量。我们还整合了空间数据来评估当前岩石开采的潜在环境和社会影响。在主要分布于北爱尔兰和苏格兰中部地带的基性硅酸盐岩石露头中确定了68个活跃的采石场和100个不活跃的采石场。估计从基性硅酸盐岩石中提取了14.8 Mt yr - 1，其中估计产生了高达370 Mt yr - 1的基性硅酸盐废物细粒，可用于英国的战争遗留武器。4.9亿吨的允许储量与活动和非活动查询相关。人工碱性矿物的空间分布，包括英国的建筑和拆除废物（CDW）和遗留矿渣也被包括在清单中。所有资源和英国农田之间的运输距离是计算出来的，这些材料可能被用于战争遗留爆炸物。英国农田的相对适宜性也根据其与矿产资源的接近程度和控制EW速率的气候参数来计算。
Enhanced Rock Weathering (ERW), a technology based on amending soils with crushed calcium- and magnesium-rich silicate minerals has substantial CO2removal potential. Evaluation of the available resources of these minerals and current production capacity is crucial for early-stage deployment of this approach. A robust understanding of the potential limitations in exploiting these resources is also required to ensure the scalability of ERW. This paper provides a spatial inventory of basic silicate rock resources in the UK along with current production capacity and permitted reserves. We also integrate spatial data to assess the potential environmental and social impacts of current rock extraction. 68 active and 100 inactive quarries were identified within outcrops of basic silicate rocks which are mainly distributed in Northern Ireland and in the central belt of Scotland. 14.8 Mt yr−1of basic silicate rock are estimated to be extracted from which up to 3.7 Mt yr−1of basic silicate waste fines is estimated to be produced which may be available for ERW in the UK. 490 Mt of permitted reserves is associated with active and inactive queries. Spatial distribution of artificial alkaline minerals including Construction and Demolition Wastes (CDW) and legacy slags in the UK have also been included in the inventory. Transport distances are calculated between all resources and the UK's croplands where these materials may be applied for ERW. The relative appropriateness of the UK's croplands for CDR are also calculated based on their proximity to mineral resources and climate parameters controlling the rate of EW.
