The 2022 Penrose Conference of the Geological Society of America on progressive rock failure (PRF2022) will bring together approximately 75 international scientists and engineers to facilitate a step-change in our understanding of rock fracture in both built and natural environments. To fully understand rock fracture is to understand elements of Earth that are critical for societal health and safety including: natural hazards related to rockfalls and landslides; degradation of rock-related infrastructure; rock weathering and erosion; and even the size and distribution of sedimentary particles and the internal structure – architecture - of Earth’s uppermost crust, which contribute to Earth’s soils and hold its water and natural resources. Yet, traditionally geoscientists studying natural rock fracture have largely overlooked the knowledge and implications to be derived from rock physics and engineering research, and vice versa. Therefore, a key goal of PRF2022 is to open doors to new insights that may be gained by studying progressive rock failure in the context of geotechnical engineering, surface processes, natural hazards and stone heritage problems. This goal will be achieved by maximizing both disciplinary diversity and participant diversity of the conference. To ensure longevity and accessibility of conference’s outcomes, PRF2022 will also provide a mentoring scheme for early career and student attendees and communicate the conference ideas with the public and among scientists themselves. There is a burgeoning recognition of 1) the central role that fractures play in Critical Zone processes, landscape evolution, and geotechnical problems; and 2) a ‘new’ realm of fracture mechanics that applies to both engineered and natural surface processes but has been understudied in those contexts - namely progressive rock failure (a.k.a. subcritical cracking, environmental cracking and microcracking). In particular, the role of progressive rock failure in natural rock fracture has been largely unrecognized or misunderstood across a wide array of both surface process and engineering applications, where it likely plays a dominant role. To best leverage recent, rapidly evolving cross-discipline conceptualizations of rock fracture and its relationship to erosion, hazards, preservation, climate, and chemical weathering, this Penrose Conference will be held in Western North Carolina, USA (June 2022). PRF2022 will: provide a platform to identify complementary data/observations and modelling approaches; reveal key existing and needed datasets; stimulate new multidisciplinary collaborations and scientific and commercial funding opportunities; and build a framework for future evaluation of PRF within both academic and applied Earth sciences questions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

2022年美国地质摇滚地质学会的彭罗斯会议（PRF2022）将召集大约75名国际科学家和工程师，以促进我们对建筑和自然环境中岩石裂缝的理解。充分了解岩石裂缝是要了解对社会健康和安全至关重要的地球元素，包括：与岩石和滑坡有关的自然危害；与岩石相关的基础设施的退化；岩石风化和侵蚀；甚至是沉积物颗粒的大小和分布以及地球上皮的内部结构（建筑），这有助于地球土壤并拥有其水和自然资源。然而，传统上研究天然岩石断裂的地球科学家在很大程度上忽略了岩石物理和工程研究的知识和含义，反之亦然。因此，PRF2022的一个关键目标是为在岩土工程，表面过程，自然危害和石材遗产问题的背景下研究渐进式岩石失败而获得新的见解。这一目标将通过最大程度地提高会议的纪律多样性和参与多样性来实现。为了确保会议成果的寿命和可及性，PRF2022还将为早期职业和学生参与者提供心理计划，并与公众以及科学家本身交流会议思想。对1）断裂在关键区域过程，景观进化和岩土技术问题中起的核心作用； 2）裂缝机制的“新”领域，适用于工程和自然的表面过程，但在这种情况下已被理解 - 即渐进的岩石衰竭（又称亚临界裂纹，环境破裂和微裂纹）。特别是，渐进的岩石故障在自然岩石断裂中的作用在很大程度上未被认可或错觉，在各种表面过程和工程应用中，它可能起着主导作用。为了最好地利用最近，迅速发展的跨学科概念的岩石裂缝概念及其与侵蚀，危害，保护，气候和化学风化的关系，该Penrose会议将在美国北卡罗来纳州（2022年6月）举行。 PRF2022将：提供一个平台来识别完整的数据/观察和建模方法；揭示现有和所需数据集的关键；刺激新的多学科合作以及科学和商业资金机会；并建立一个在学术和应用地球科学问题中对PRF进行评估的框架。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准通过评估来诚实地支持。
