The Science Behind Laboratory-Scale Models
of the Earth
Outstanding Student Paper Awards
Workshop on Advances in Quantitative Analogue Modelling (AiQAM);
Potsdam, Germany, 23–25 September 2013
presentations and the following plenary discussions made the experimentalist community aware of the pros and cons of each
method and helped participants identify the
relevant method for their specific needs.
The workshop had several major outcomes. First, the community learned about
the theoretical concepts behind each presented method, which is crucial for optimized use. It is essential for users to understand the limitations of each technique,
which have often been used as ­press-​­button
“black boxes.”
Second, the group agreed to write a methodological review paper listing the main
image analysis techniques discussed during
the workshop, which would be useful for the
experimentalist community.
Third, the group defined and discussed
two main future challenges of tectonic and
volcanological laboratory modeling, including quantifying stresses within the models
and integrating the quantitative data sets
with geophysical, geodetic, and numerical
modeling results. To these aims, a dedicated
session on methodology (in both numerical
and analog modeling) and a short course
on the derivation and implementation of
deformation laws have been planned at the
upcoming GeoMod meeting for modelers in
solid Earth geoscience, to be held in September 2014 at GFZ Potsdam.
Matthias Rosenau is gratefully acknowledged for his participation in the planning
of the workshop, as is the Marie Curie International Training Network’s “Sculpting the
Earth’s topography: Insights from modelling
deep Earth processes” (­TOPOMOD) project
for funding support.
Deformation processes involve systems
of tens to hundreds of kilometers moving at
highly variable rates. Because direct kinematic observations have proven difficult,
geoscientists are sometimes found in the lab
creating analogs, or laboratory models of
the Earth. The main scope—and a key challenge—of laboratory modeling of Earth systems is to provide a quantitative approach for
understanding geological processes. Since
the last decade, various image analysis techniques in laboratory modeling have been
designed and used to constrain the kinematics of the simulated processes at an unprecedented resolution. These techniques prove to
be the key quantification tools in experimental modeling, not only allowing mechanical
analysis of the experiments but also producing experimental data sets that are directly
comparable to geophysical and geodetic data
in nature and numerical models.
Reporting and integrating these advancements was the objective of an international
workshop on Advances in Quantitative Analogue Modelling (­AiQAM), held at the German Research Center for Geosciences (GFZ)
in Potsdam. The workshop was attended by
32 researchers in the fields of tectonics, volcanology, remote sensing, and fluid dynamics from research centers in Europe, the
Americas, and Asia. The focus was on image
processing and analysis methods for quantitative deformation analysis. The workshop
was followed by a short practical course on
application of particle image velocimetry
(PIV) in the experimental laboratory.
The aims of the six invited talks and the
poster presentations were threefold: to list
the state-of-the-art image analysis techniques used in the laboratory for the experimentalist community, to identify the outcome data sets of each presented method
(­2-D, ­3 -D, or ­4 -D), and to discuss in detail
the procedures to process and mechanically interpret these data sets. These
