Investigations using portable X-ray fluorescence, X-ray diffraction and scanning electron microscopy with energy dispersive spectroscopy as well as micromorphological analyses were carried out to gain a better understanding of the corrosion processes affecting the copper alloy artefacts, by characterising the alloy composition, soil environments, and corrosion products. Preliminary results indicate that the artefacts consist of copper-lead-tin alloys, covered by copper hydroxy-chlorides and lead sulphate phases with slight variations in their crystallisation. The multi-analytical approach revealed the presence of quartz, calcite, gypsum and feldspars in the sediments, while thin sections more specifically indicate loess soils with local micro-environments.

This data can be used to improve research about the preservation and visibility of the archaeological record, and it can also aid heritage management. This paper presents a composite Image-Based Modelling workflow to generate 3D models, historical orthophotos, and historical digital elevation models from images from the 1970s. This was done to improve the interpretation of survey data from the early Roman colony of Aesernia. The main challenge was the lack of high-resolution recent digital elevation models and ground control points, and a general lack of metadata. Therefore, spatial data from various sources had to be combined. To assess the accuracy of the final 3D model, the Root Mean Square Error (RMSE) was calculated. While the workflow appears effective, the low accuracy of the initial data limits the usefulness of the model for the study of geomorphological change. However, it can be implemented to aid sample area selection when preparing archaeological fieldwork. Additionally, when working with existing survey datasets, areas with a high bias risk resulting from post-depositional processes can be indicated.

Due to the voluminous corrosion products and the decay of organic materials, the information contained in these objects is generally not accessible when they are left untreated. The decision is often made between either full treatment of all objects or no treatment at all.
This research offers an alternative solution to the question of treatment versus no treatment. X-ray and μCT imaging techniques were applied to iron objects from the early Medieval cemetery of Lentseveld (in The Netherlands), and these methods were combined with selective, investigative, and full cleaning. These methods and techniques vary in their approaches and results, and combining them can be useful. The strategy depends on the needs of a particular project and specific research questions. Objects from such a context often have no metal left at all. After many centuries of post-depositional processes, they consist almost entirely of corrosion products. Of particular interest for this paper are the results that can be obtained using techniques such as μCT to see through corrosion and soil.
The results include object outlines; internal structures and cross-sections; related objects; and associated materials. This research shows that applying and combining methods in a pragmatic manner has a clear advantage in terms of the achievable duration and obtainable information compared with the traditional strategy. It also suggests that μCT can contribute to both the conservation and interpretation of archaeological iron objects, especially larger object assemblages.

Advisory text specifying possibilities and levels of conservation versus expected results for specific object groups to improve time and cost efficiency by streamlining the process and research without compromising objects and treatment quality.

A survey of the research potential of archaeological finds results in four levels of information that will be considered in every step of the conservation process for iron finds.
Examples of different conservation techniques for iron objects, mostly from burial sites, ranging from standard conventional X-ray radiography, in combination with partial cleaning, to Computed Tomography (CT), are evaluated in regard to the information they reveal that is relevant to the archaeological research. Ultimately, a well thought out balance between common methods and new techniques will result in the most effective approach.

Their application is increasingly prevalent due to their lower cost and increased ease of use. Examples include satellites and unpiloted aerial vehicles (UAVs) with RGB, laser, and spectral sensors; geophysical techniques such as magnetometry, GPR, and resistivity; and Artificial Intelligence (AI) for data collection and interpretation.

Nowadays, there are significant variations in the archaeological research traditions in the
area, influencing the methodological approaches and the potential future research. In
the past decades, archaeological research has become an increasingly interdisciplinary
field, applying and combining knowledge from several scientific disciplines. While the
compatibility of the approaches brought forth by these disciplines is not always obvious,
these multifaceted approaches enable to “think outside the box” and create innovative
methodologies. Regardless of the numerous advantages of this approach, a well-defined
goal is frequently lacking in interdisciplinary studies.
This session intends to continue the fruitful discussion brought forth during the EAA2020
session “How to promote inter- and transdisciplinarity in Mediterranean Archaeology?”
by exploring previously identified issues and working towards the establishment of more
inter- and transdisciplinarity in training and research.
Papers discussing projects and case studies related to Mediterranean Archaeology that
involve the combination of various disciplines are encouraged. Contributors are invited to
share their experiences, obstacles, and solutions. The session will aim to address
questions along the following lines:
- What are the best practices employed to study materials and cultures in an inter- or
transdisciplinary way?
- What are the questions we can and need to ask, depending on the material?
- How to advocate for a specific approach within the project, especially when budget and
time are limited?
- Who formulates the main goal? (Different fields have different questions to ask and
different approaches)
- What is the professional identity of the inter- or transdisciplinary researcher?
