This award will support participants in a conference that will be convened in Seattle (WA) on October 2017 with the purpose of disseminating new knowledge and skills for the integration of petrology and geochronology. The primary audience for the conference is composed of graduate students, early-stage researchers as well as established professionals that would like to learn this new methodology. Through this type of training, early-career investigators will be able to develop future research directions that, in turn, will promote the advancement of the fields of petrology and tectonics. The conference will be held in the Washington State Convention Center, and will emphasize lecture-style presentations from experts in the discipline, and include a demonstration of data reduction software and possibly additional discussion time to identify areas of improvement of these methods. The first day will cover theory and analytical methods, and begin the systematic survey of relevant mineral systems. The second half-day will complete discussion of petrogenetically useful minerals and the presentation of useful software followed by discussion. Participants will be recruited from the broader communities interested in developing these new skills.Petrochronology has emerged in the last 5-10 years as a preferred approach to geochronology, basically using chemistry and/or textures to integrate ages of individual crystals or crystal domains into a petrogenetic context. Examples in metamorphic systems include the use of crystal domain-specific trace element patterns or thermometers in minerals like zircon, monazite, titanite and garnet to link an age to an overall P-T-t evolution. Examples in igneous systems include resolution of crystal residence times, timing and rates of magma recharge, and rates of magma transport from zoning in quartz, olivine, feldspar, and melt (glass). Petrochronology directly benefits studies of tectonics, and metamorphic and igneous petrogenesis. It is expected that a corresponding book, published through "Reviews in Mineralogy and Geochemistry", will provide an important foundation accessible to high-level undergraduate students, graduate students, and junior professional researchers who are interested in theory and applications within this burgeoning field.

该奖项将支持将于 2017 年 10 月在西雅图（华盛顿州）召开的会议的参与者，该会议的目的是传播岩石学和地质年代学整合的新知识和技能。会议的主要受众由研究生、早期研究人员以及希望学习这种新方法的知名专业人士组成。通过这种类型的培训，早期职业研究人员将能够开发未来的研究方向，进而促进岩石学和构造学领域的进步。会议将在华盛顿州会议中心举行，重点是该学科专家的讲座式演讲，包括数据缩减软件的演示，以及可能的额外讨论时间，以确定这些方法的改进领域。第一天将涵盖理论和分析方法，并开始对相关矿物系统进行系统调查。后半天将完成对石油成因有用矿物的讨论以及随后讨论的有用软件的演示。参与者将从对开发这些新技能感兴趣的更广泛的社区中招募。岩石年代学在过去 5-10 年中已成为地质年代学的首选方法，基本上使用化学和/或纹理将单个晶体或晶体域的年龄整合到一个岩石成因背景。变质系统的例子包括在锆石、独居石、钛矿和石榴石等矿物中使用晶域特定的微量元素模式或温度计，将年龄与整体 P-T-t 演化联系起来。火成岩系统中的示例包括晶体停留时间的分辨率、岩浆补给的时间和速率，以及石英、橄榄石、长石和熔体（玻璃）分区中岩浆传输的速率。岩石年代学直接有利于构造学、变质岩和火成岩成因的研究。预计通过“矿物学和地球化学评论”出版的相应书籍将为对这一新兴领域的理论和应用感兴趣的高水平本科生、研究生和初级专业研究人员提供重要的基础。
