The dating of events and studying the timescales of processes are central objectives of Geosciences. Technological advances now make it possible to determine the concentrations of radioactive decay products, and hence dates, with an ever-increasing accuracy from sample volumes that are becoming smaller by the day. Thus, a rapid sequence of short-lived events may now be dated separately and accurately from in-situ samples (i.e., without the need for dissolution, maintaining the spatial textural contexts) with remarkable spatial resolution. In this effort, the most challenging step remains the need to associate each date with a specific geological event—in brief, to know: What is it that we are dating? It is in this challenging field that Daniela Rubatto established herself rapidly as a leader, and it would not be far-fetched to say that she was one of a handful of people who were instrumental in initiating what has now come to be known as a separate area of research—Petrochronology (a topic of a RiMG volume in 2017). What is remarkable is that some of the key papers that led to this development were published only a few years after the completion of her Ph.D., during the early days of her post-doctoral research work.People supporting Daniela’s nomination have discussed different sets of papers and their impact on the field. Today I will single out the astute choice of problem that is a sign of the scientific maturity that Daniela demonstrated coming right out of graduate school. While the need to relate dates to events has been a well-known issue to tackle, one could choose any number of different systems in which to explore the problem. Daniela picked garnets and zircons, recognizing that the pair is by far the most widely used mineral system for the determination of pressure-temperature conditions of formation (garnets) and dates (zircons), respectively. Therefore, connecting the two would considerably multiply the insights gained from either one by itself and provide a much more comprehensive picture of metamorphism than had been possible until then.As is often the case, solving challenging problems requires interdisciplinary approaches that borrow methods and skills from different areas. Daniela did just that, marrying isotope geochemistry with phase petrology as well as experimental petrology (the last part in collaboration with Jörg Hermann, another recipient of a Dana Medal). The process was initiated with her sole authored paper in Chemical Geology in 2002. Path-breaking research is defined by the quality that such work not only solves a long-lasting problem but also that the idea it germinates triggers a whole new direction of research. In this case, others began to apply ideas introduced in the 2002 paper to other accessory minerals used for geochronology (monazite, allanite) and to major rock-forming minerals used to determine conditions of formation (e.g., plagioclase, amphiboles). Daniela would not be Daniela if she were to rest on her laurels—she herself took a very active part in the process as well and has gone on to establish herself as the expert on accessory mineral dating and petrochronology. Her highly cited studies using monazite, allanite, or rutile are not her most visible contributions only because they are in competition with her extraordinary oeuvre of contributions on zircon. Indeed, the development of such new approaches has to run in parallel with new developments in analytical methods and instrumentation, and Daniela has not shied away from those either.Providing such major tools to the community would be accomplishments worthy of recognition by themselves, but Daniela has contributed more. She has always been curious to test how the tools developed by her perform in the field and what insights they offer. For this, she has teamed up with scientists from all over the world and from many different areas (petrologists, geochemists, structural geologists, and more) to address research problems that span the entire history of the earth (from very early Earth events to products of the most recent tectonic processes) and about a dozen different orogens (Alps, Himalaya, SE Spain, Bohemian Massif, Kokchetav, Rajasthan, Tianshan, Reynolds Range, New Caledonia, Limpopo Belt). She has traveled widely to field areas in all corners of the world to carry out this research. This last aspect, in particular, takes on a different significance when one considers that she has balanced raising children and a very active dual career family at the same time, demonstrating along the way how it can be a lot of fun!Daniela’s work has demonstrated that metamorphic processes can occur at rates comparable to those of plate motions. However, it has also revealed more nuanced variations that show that the processes are pulsed and are probably related to individual events of dehydration or fluid flux. Thus, a need to correlate dates to not just pressures and temperatures of formation but also fluid-related events has emerged, and Daniela’s current research is aimed at exploring such connections.Daniela’s broad spectrum of contributions is a result of her dynamic nature, her excellent team-building capabilities, and her highly disciplined management of projects. Beyond her own science, she has contributed to the community in many different ways. She is an untiring mentor to young scientists (she has advised over 25 Ph.D. students and mentored many more early career researchers). As one of her letter writers noted, it is in her interactions with her students and postdocs that her intensity, excitement, and dedication to science shows most prominently. She has been involved in editorial activities of several leading journals in the field, has been a contributor to RiMG volumes and Elements, was chair of the science committee of the Goldschmidt conference in 2018, and was an MSA distinguished lecturer, in addition to being a Keynote lecturer at a number of high-profile international conferences.Daniela has established herself as a leading metamorphic geo-chemist of our time and has been a driving force behind the emergeing field of petrochronology. She is one of the leading experts on isotopic studies of accessory minerals. She has accomplished this in a remarkably short time, with an exemplary work-life balance. It is my pleasure and privilege to present to you the awardee of MSA’s Dana Medal for 2020—Daniela Rubatto.

向丹妮拉·鲁巴托（Daniela Rubatto）颁发2020年美国矿物学学会达纳奖章

事件的约会和研究过程的时标是地球科学的主要目标。现在，随着技术的进步，可以确定放射性衰变产物的浓度，从而确定日期，并且可以通过日渐缩小的样品量来提高其准确性。因此，现在可以用非凡的空间分辨率与原位样品（即无需溶解，保持空间纹理环境）分别快速准确地确定短暂事件的快速序列。在这项工作中，最具挑战性的步骤仍然是将每个日期与特定的地质事件相关联的必要性—简而言之，要知道：我们正在约会的日期是什么？在这个充满挑战的领域，丹妮拉·鲁巴托（Daniela Rubatto）迅速确立了自己的领导地位，可以说她是少数人中的一员，这些人对启动如今被称为一个单独的研究领域-天文年表（2017年RiMG卷的主题）的人极少。引人注目的是，促成这一发展的一些关键论文在其博士学位完成后的几年内，即博士后研究工作的早期才发表。支持Daniela提名的人们讨论了不同的观点。套论文及其对实地的影响。今天，我将挑选出最明智的问题，这是丹妮拉（Daniela）刚从研究生院证明的科学成熟度的标志。尽管需要将日期与事件相关联已成为一个众所周知的问题，人们可以选择许多不同的系统来探索问题。Daniela挑选了石榴石和锆石，并认识到这对是分别用于确定地层（石榴石）和日期（锆石）的压力-温度条件的最广泛使用的矿物系统。因此，将两者联系起来将大大增加从一个人本身获得的见解，并提供比以前更全面的变质情况。解决挑战性问题通常需要跨学科方法，这些方法应借鉴和借鉴不同地区。Daniela做到了这一点，将同位素地球化学与相岩石学以及实验岩石学相结合（最后一部分与达纳奖章的另一位获得者约格·赫尔曼（JörgHermann）合作）。该过程始于她2002年在《化学地质学》上发表的第一篇论文。开创性的研究被定义为这样的质量，即这种工作不仅解决了一个长期存在的问题，而且其发芽的思想触发了一个全新的研究方向。在这种情况下，其他人开始将2002年论文中介绍的思想应用到其他用于年代学的辅助矿物（独居石，长石）和用于确定形成条件的主要成岩矿物（例如斜长石，闪石）。如果丹妮拉不为所动，就不会成为丹妮拉（Daniela）-她自己也非常积极地参与该过程，并逐渐确立了自己作为辅助矿物定年和岩石年代学专家的地位。她使用独居石，尿囊石，金红石或金红石并不是她最引人注目的贡献，仅仅是因为它们与她在锆石上的非凡贡献相抗衡。的确，这种新方法的开发必须与分析方法和仪器的新开发同时进行，但Daniela也不回避这些。向社区提供这样的主要工具将是值得他们自己认可的成就，但Daniela贡献了更多。她一直很想测试她开发的工具在该领域的表现以及它们提供的见解。为此，她与来自世界各地和许多不同领域的科学家（岩石学家，地球化学家，结构地质学家，等）来解决整个地球历史（从很早的地球事件到最近的构造过程的产物）以及大约十二种不同的造山带（阿尔卑斯山，喜马拉雅山，西班牙东南部，波西米亚地块，科克切塔夫，拉贾斯坦邦）的研究问题，天山，雷诺山脉，新喀里多尼亚，林波波带）。她已广泛前往世界各地的田野地区进行这项研究。当人们考虑到她同时平衡抚养子女和一个非常活跃的双重职业家庭时，这最后一个方面具有不同的意义，一路证明了这是多么的有趣！Daniela的作品已经证明了这一点。可以以与板块运动相当的速率发生变质过程。然而，它还揭示了更细微的变化，这些变化表明过程是脉冲性的，并且可能与脱水或流体通量的个别事件有关。因此，不仅需要将数据与地层的压力和温度相关联，而且还需要将与流体相关的事件相关联，丹妮拉（Daniela）目前的研究旨在探索这种联系。团队建设能力，以及她高度纪律的项目管理能力。除了自己的科学之外，她还以许多不同的方式为社区做出了贡献。她是年轻科学家孜孜不倦的导师（她为超过25名博士生提供了建议，并为更多早期职业研究人员提供了指导）。正如她的一封信的作者所指出的那样，在与学生和博士后的互动中，她的强烈，激动和对科学的奉献精神最为突出。她曾参与该领域几家主要期刊的编辑活动，曾为RiMG卷和Elements撰稿，曾于2018年担任Goldschmidt会议科学委员会主席，并曾担任MSA杰出讲师。丹妮拉（Daniela）已成为当今时代领先的变质地球化学家，并一直是岩石年代学新兴领域的推动力。她是辅助矿物同位素研究的领先专家之一。她在极短的时间内就实现了这一目标，并取得了良好的工作与生活平衡。
