Welcome to the official website of the 3rd D.I.N.G.U.E. Conference, to be held on the 24th and 25th August 2013 at the University of Florence, Italy (immediately prior to the 2013 Goldschmidt conference).

During this two days meeting, noble gas geo- and cosmo-chemists will be invited to discuss technical and scientific aspects of new noble gas applications to terrestrial and extraterrestrial science.

24th & 25th August 2013

Important! This workshop is now fully booked. Only people who have submitted an abstract will now be allowed to register.

The registration deadline is 25th June 2013.

Abstracts
The abstract deadline is 12th April 2013. Abstracts should be directly submitted to the DINGUE3 workshop organizers via the abstract submission form (submission now closed).

Registration
The registration deadline is 25th June 2013. Registrations have to be done on the Goldschmidt website.
Important! This workshop is now fully booked. Only people who have submitted an abstract will now be allowed to register.

The registration fee is €65 (limited student grants will be available, please see the student grants section).

Registration includes refreshments, 2 lunches (Saturday 24th and Sunday 25th August) and the workshop dinner (Saturday 24th August). Special requests about food should be addressed to the organizers by email or via the contact form.

People wanting only to attend the DINGUE3 workshop (but not the Goldschmidt 2013 conference) should register using the category “Accompanying person, social only (€0)” in the first page of the registration process on the Goldschmidt website, before ticking the box corresponding to the workshop in the following webpage.

Keynote Speaker: Igor Tolstikhin
Igor discovered the primordial 3He in the mantle and the tritium-3He water dating technique. Both had a profound impact on our understanding of the Earth system. He will receive this year during the Goldschmidt conference the Urey award (EAG) and will honour us with giving the keynote of D.I.N.G.U.E. 3 workshop:

Noble gas sites, mobility and sources in rocks (minerals) of the continental crust.

There are two principal components of noble gas isotopes in minerals. One of these is produced in mineral in situ due to natural nuclear processes: decay, fission, nuclear reactions (hereafter radiogenic* species). This component is important for the “old” minerals, discussed in the presentation. The second component comprises gases which originated outside of the mineral and then were trapped during mineral formation or evolution (trapped species). Radiogenic* nuclides along with the parent isotopes are generally used for radiometric chronometry, whereas trapped gases recorded sources of (and respective processes related to) fluid components. To distinguish between these two components and present reasonable interpretations of each of them, knowledge of the sites and mobility of noble gas atoms in a mineral is required, which also allows specific features of the gas-hosting mineral to be derived. This requirement is not simple to perform and therefore it is in many cases ignored, leading to simplistic and even incorrect conclusions. The following examples illustrate the importance of detailed study of sites and migration rates of noble gases in minerals along with the abundances of the parent elements.
The first story illustrates the enormous difference of helium mobility in “one and the same mineral”, e.g., quartz. Here I compare results obtained for (i) a honeycomb quartz crystal (1815 Myr old, Volyn, Ukraine), characterized by almost “perfect” retention of helium isotopes, and (ii) quartz grains (separated from 280 Myr old sandstone, Molasse, Switzerland). In the latter case helium migration through the grains is so fast, that its concentrations inside the grains and in the interstitial pore water approach equilibrium in 10 Kyr, which make it possible to use quartz grains as detectors of the pore water helium concentration.
The second example relates to He and Ar isotope abundances in ancient alkaline granites (2860 Myr old, Kola Peninsula, Russia). Five different sites of noble gas atoms in one mineral (ilmenite), separated from these rocks, are observed: (i) radiogenic* helium in separated “closed” α-tracks, (ii) radiogenic* helium in large globular defects (probably around micro-inclusions of a radioactive mineral), (iii) radiogenic (but not in situ generated and almost un-supported by helium) argon, trapped during metamorphism of the granites, (iv) helium and argon trapped in fluid inclusions during mineral formation, (v) radiogenic* argon.

The programme for the DINGUE3 conference is still being compiled. Please check back soon!

Student Grants

Student grants will be provided by the European Association of Geochemistry (EAG). Grants up to €200 may be awarded and will cover at least the registration fee of €65.

To apply for EAG grants, students must:

  • submit an abstract for the workshop (submission now closed)
  • register for the workshop on the Goldschmist website – the deadline is 25th June
  • send to the DINGUE3 organisers a proof of student status (e.g. student card or a letter from the supervisor) at dingue3@noblegasgeochemistry.com – the deadline is 25th June

Students who only want to attend the DINGUE3 workshop (but not the Goldschmidt conference) should directly contact the DINGUE3 organizers – the deadline is 25th June.

Students awarded grants will be asked to write a small report (400 words) relating their experience at the workshop. Based on this material, the EAG may ask some students to post their report as part of the EAG blog.
