Please contact Paul Asimow or Paula Antoshechkina if you have any questions and please check the website link for the latest news. PLEASE CHECK THE AlphaMELTS2 WEB PAGE FOR DATES AND TIMES, the date and time stated above may not be accurate. **

The MELTS family of algorithms is widely used by petrologists and geochemists to predict the outcomes of melting and crystallization processes, to compare with experiments or to design experimental campaigns, to assess the energy budgets of igneous processes, to teach the principles of igneous petrology, and more. Although there are a variety of ways to access such models, this workshop will focus on the newly released alphaMELTS 2 interface, and alphaMELTS for MATLAB/Python. alphaMELTS 2 is a text-based front end to the Rhyolite-MELTS, pMELTS, and pHMELTS models, with built-in trace element calculations and a variety of unique features and workflows. (Note that no commercial software is required for the workshop; access to alphaMELTS from MATLAB or Python is near-identical, so users may select one or the other.) This two-day workshop will be structured to appeal to a wide range of users, who may choose to attend either one or both days. Day 1 will focus on introductory material and basic functionality for new users, whereas Day 2 will focus on the latest features, more advanced or larger-scale calculations, and special problems suggested by attendees. Day 1 will constitute sufficient preparation for a novice to be able to appreciate Day 2. Instructors Paul Asimow and Paula Antoshechkina from Caltech are the designers and maintainers of alphaMELTS 2, and related software, and will cover software installation as well as some undocumented tricks that are important to getting reliable results from MELTS calculations.

Applications of isotope tracers to geochemical kinetics studies

Sunday 21st June 14:00 - 21:00
Contacts: Chen Zhu, Jim Kubicki

**This workshop will be managed and run virtually from Indiana University on Sunday 21st June 2020. The workshop is free. Please refer to the weblink above for more details. PLEASE CHECK THE WEB PAGE FOR TIMES, the time stated above may not be accurate**

The isotope tracer method promises detection that is orders of magnitude more sensitive than the conventional method that uses concentrations (e.g., Si, Al) to measure reaction rates. The method introduces an enriched rare isotope of an element to an experimental solution that is interacting with a mineral or a suite of minerals that have normal or natural isotopic compositions. Although the method itself is not new, MC-ICP-MS technologies now make the measurement of many non-traditional isotopes accessible. The first objective of this workshop is to impart the methods and skills of designing, preparing, and interpreting experiments. The workshop will also provide a venue to link participants with laboratories that possess capabilities for analysis of non-traditional stable isotopes through short presentations and posters from the labs. The second objective of the workshop is to discuss various topics pertinent to the effective uses of the isotope tracer method in geochemical kinetics studies. These topics may include potential innovative experimental designs and theoretical models, as well as potential pitfalls. We plan to discuss with GCA or Chemical Geology the possibility of a cluster of papers. We will also discuss a possible proposal to the NSF Research Coordination Network program.

If this Crystallization via non-classical pathways is important during the formation of minerals in nature and has become to a popular method to synthesize advanced materials at both the lab and industrial scales. Unlike either classical crystal growth pathway via monomer-by-monomer addition or Ostwald ripening, crystallization via non-classical pathways such as particle-by-particle attachment can form bigger crystals, faster. Up to now, plentiful materials prepared via classical crystallization have been applied in various fields such as energy, catalysis, biomedicine, optics, electrics, and magnetics. Understanding crystallization via non-classical pathways could provide new insights on design and synthesis of novel materials. The workshop aims to bring to researchers updated information on the fundamental non-classical crystallization research, including theory and experiments. It is also designed for the experienced researchers to reinforce their knowledge on the scopes of development of new techniques, especially state-of-the-art in situ characterization tools, to understand mechanisms of crystallization via non-classical pathways. The topics that would be covered in this workshop include: ● Non-classical nucleation ● Crystallization via cluster aggregation ● Mineral formation from amorphous precursors ● Biomineralization via non-classical pathways ● Particle-based crystallization, such as oriented attachment and mesocrystals ● Observation of the non-classical crystallization pathways via in situ techniques ● Theoretical developments to simulate non-classical crystallization

Tuesday 23rd June 19:30 - 20:30
Contacts: Laurent Valentin
Location: Room 3, Goldschmidt2020 - Virtual Venue View on map
Price: US$0

Student engagement (SE) is what a student brings to Higher Education in terms of goals, aspirations and values and how these are shaped by their experience as students. These include 1) Expressing individual opinions and ideas, 2) Taking an active role in academic life, 3) Collaborating with staff and students in decision-making over both the process and outcome. There are many different examples of students and staff working in partnership to co-create learning and teaching experiences. These initiatives include examples of students as co-researchers, students as change agents, students as consultants and students as co-creators of curricula. This workshop is designed to provide guidance and strategies for students and academic staff wishing to initiate, sustain or extend student-staff partnerships. The aims of the workshop are threefold, i) explore the ways in which students act as partners in learning and teaching, ii) identify strategic and sustainable practices of engaging students as partners, iii) discuss the risks and challenges inherent to partnership and find suggestions for addressing them.

The fee is $40 and this will be donated to a fundraiser for earth sciences undergraduate field trips**

Geospeedometry, the science of extracting timescale information from element diffusion in minerals and melts has undergone a major surge in igneous and metamorphic petrology over the last two decades. As analytical and computational tools are improving quickly, applications of diffusion chronometry leveraging multiple elements (majors, minor and traces) in the same mineral or melt are becoming routine. Be part of this exciting and rapidly developing field and join us for a two-day workshop covering the underlying principles, analytical and numerical techniques, and uncertainties in applying diffusion modeling to magmatic and metamorphic systems. We will cover some basic background through a series of short talks, but mostly, emphasis will be put on gaining practical coding skills to start your own diffusion models using Excel®, and trying out more sophisticated programming tools like Matlab®. Several exercises encompassing analytical solutions and numerical finite differencing in 1D (and potentially 2D), all grounded in real case studies, will be utilized. We will also discuss uncertainties, potential pitfalls, unsolved diffusion mysteries, and areas that we as a community can help improve on in the years to come. The workshop is also co-organized by metamorphic petrology and diffusion expert Wali Faryad.
