A Workshop on Neutrino Geoscience will be held in September 2008 at SNOLab (Sudbury Neutrino Observatory Laboratory). This 2.5-day meeting will have geology and particle physics talks focused on recent developments in global and Canadian geology, and geoneutrino experiments at SNO (Sudbury Neutrino Observatory), KamLAND and Borexino. There will be ~60 participants, with roughly equal representation from both communities. There will be a tour of the SNO underground facility, including a view of the SNO+ experimental environment. This meeting will engage the North American geological and particle physics communities in an effort to foster collaborative research. The particle physics community seeks feedback and insights from the geological community in regards to knowledge about the K, Th and U content in the nearest 500 km radius, half-spherical volume beneath the SNO+ detector. The meeting organizers include Drs. Mark Chen (Queens University, Ontario, Canada), Claude Jaupart (University of Paris, France), Bill McDonough (University of Maryland, USA) and Roberta Rudnick (University of Maryland, USA). Significant progress has been made in exploiting the practical utility of antineutrino detection for geological and nonproliferation purposes, in particular, reactor monitoring. Despite these remarkable successes, these inter-related communities have had only modest overlap. As a result, the fields of applied and basic antineutrino physics lack an overarching strategy that would allow efficient exploitation of the resources and strengths provided by each stakeholder. This workshop aims to develop the basis for such a strategic alignment of interests between the fundamental and applied antineutrino physics communities, including geosciences.Broader Impact: The geonneutrino signal represents a background contribution to a global antineutrino signal, which also includes contributions from nuclear reactors and weapons related nuclear materials. Thus, understanding in detail the geoneutrino contributes greatly to the viability of antineutrino detection for nuclear nonproliferation purposes. Some applications are potentially important to maintaining a safe society that uses such nuclear materials. Intellectual Merit: The importance of this workshop will be to unite disparate groups of multi-disciplinary scientists with shared goals in antineutrino detection research and applications. A goal of the workshop is to develop stronger bonds of communications between these fields. This step is necessary in order to fully understand the various the components of an antineutrino spectrum and identify correctly the sources of the signal.

中微子地球科学讲习班将于2008年9月在SNOLab（萨德伯里中微子观测实验室）举行。这次为期2.5天的会议将有地质学和粒子物理学的会谈，重点是全球和加拿大地质学的最新发展，以及SNO（萨德伯里中微子天文台），KamLAND和Borexino的地中微子实验。将有大约60名参与者，两个社区的代表人数大致相等。参观SNO地下设施，包括SNO+实验环境。这次会议将使北美地质和粒子物理界参与，努力促进合作研究。粒子物理学界寻求地质学界的反馈和见解，以了解SNO+探测器下方最近500公里半径的半球体中K、Th和U的含量。会议组织者包括Mark Chen博士（加拿大安大略皇后大学）、Claude Jaupart博士（法国巴黎大学）、Bill麦克多诺博士（美国马里兰州大学）和Roberta Rudnick博士（美国马里兰州大学）。在为地质和不扩散目的，特别是反应堆监测利用反中微子探测的实际效用方面，已经取得了重大进展。尽管取得了这些显著的成就，但这些相互关联的社区只有少量重叠。因此，应用和基础反中微子物理学领域缺乏一个总体战略，可以有效利用每个利益攸关方提供的资源和优势。本次研讨会的目的是发展的基础和应用反中微子物理学社区，包括地球科学之间的利益，这样一个战略联盟的基础。更广泛的影响：地中微子信号是一个全球反中微子信号的背景贡献，其中还包括来自核反应堆和武器相关的核材料的贡献。因此，详细了解地中微子有助于反中微子探测的可行性，为核不扩散的目的。有些应用对维持使用这种核材料的安全社会具有潜在的重要性。智力优势：这次研讨会的重要性将是团结不同的多学科科学家群体，在反中微子探测研究和应用方面有着共同的目标。讲习班的一个目标是加强这些领域之间的交流。这一步是必要的，以便充分了解反中微子光谱的各种成分，并正确识别信号的来源。
