“…This versatile technique is used at different scales, for reading satellite images, creating terrestrial geological maps, analyzing the lunar surface, and for mining explorations [37][38][39][40]. In archaeology, infrared spectroscopy has been widely used for surveys of aerial or satellite images [41,42] and provenance studies [24,[43][44][45][46][47][48]. All infrared spectra contain diverse information that refers to the various properties of the materials.…”

“…Near infrared spectroscopy does not deliver quantitative information about the composition of a particular stone but each infrared spectrum constitutes a unique fingerprint of the material. NIR portable probes can be used for collecting data on geological artifacts in situ, the datasets grant a good representation of molecular features and can be considered a preliminary step in the identification of raw material supply sources (see the detailed comparison and combination of NIR and XRF [47]).…”

The study of stone artifacts and their provenance is an important proxy for understanding the entangled relationship between humans and geological resources. In this paper, we explore the potentialities of an interdisciplinary approach combining in situ documentation of tool marks and characterization of stone types using a near infrared (NIR) portable probe. We argue that this protocol is useful for collecting screening data on objects that cannot be moved or sampled. NIR spectra describe textural and molecular features of the materials and can be used to achieve a preliminary characterization of raw materials. We present a case study from the territory of Montescaglioso (Basilicata, near Matera, Italy), where we combined the analysis of a calcarenite (limestone) quarry, in Masseria D’Alessio, which was exploited since the 6th century BC, as well as artifacts of the same chronology from surveys and excavations in the surroundings. The aim was to collect preliminary data about the distribution of the particular calcarenite extracted from the quarry and identify exploitation and trade patterns. The data were processed using multivariate statistics to highlight the relevant spectral information and perform supervised classification of spectral features. Documentation of tool marks and the process of stone working were combined with the spectral signature of the artifacts to link the stone types to the description of their extraction/carving methods.

“…The different spectrometry techniques are focused on the analysis of the composition of materials. Portable equipment such as hyperspectral cameras, RX equipment or spectroradiometers, make it possible to perform analysis of this nature without the need to extract a sample for laboratory analysis [33][34][35]. Working methods with the spectral techniques applied to heritage are described in [33].…”

“…For the cataloging of these, given the size and manageability, the analysis of spectral nature in order to establish similarities and differences between the pigments of different areas of the same work, has been of greater application [33,36,37]. For buildings, the use of these techniques is focused on archaeological and constructive studies as shown in [34,35]. In these works, the origin or composition of materials are determined from the spectral analysis differences, so that construction times or pathological conditions can be established.…”

The Tower of Belém, an early 16th century defense tower located at the mouth of the Tagus river, is the iconic symbol of Lisbon. It belongs to the Belém complex, classified since 1983 as a World Heritage Site by the UNESCO, and it is the second most visited monument in Portugal. On November 1st, 1755, there was a heavy earthquake in Lisbon followed by a tsunami, causing between 60,000 and 100,000 deaths. There is a possibility of a repetition of such a catastrophe, which could bring about the collapse of the structure. This was the reasoning behind the decision to evaluate the Tower of Belém by means of surveys using Terrestrial Laser Scanning and photogrammetry. Until now, there was no high-resolution 3D model of the interior and exterior of the tower. A complete 3D documentation of the state of the Tower was achieved with a cloud of more than 6,200 million 3D points in the ETRS89 PT-TM06 coordinate system. Additionally, measurements were made using a hyperspectral camera and a spectroradiometer to characterize the stone material used in the Tower. The result is a digital 3D representation of the Tower of Belém, and the identification of the quarries that may have been used to extract its stone. The work carried out combines geometrical and material analysis. The methods used may constitute a guide when documenting and intervening in similar heritage elements. Finally, the information contained therein will allow an eventual reconstruction of the Tower in the case of another catastrophe.

“…Some scholars have been focused on verifying the reliability of using FPXRF in archaeology [6][7][8][9][10]. Except for that, FPXRF has also been used with other instruments to study diseases of heritage building materials such as bricks and stone masonries [11][12][13][14][15][16].…”

Linqing brick is very famous in Chinese history. In 2008, "The manufacturing process of Linqing brick" was selected as the intangible cultural heritage list in China. Now in China, how to identify the origin of Linqing brick is an important issue in archeology and architectural history research. It can be used to verify some assumptions about the history of heritage buildings which cannot be solved only by historical documents. It can also be used to study the history of Linqing brick. Field portable X-ray fluorescence spectrometry (FPXRF) can quickly and non-destructively determine the main elements and concentrations of Linqing brick in situ. It may be significant for identifying the origin of Linqing brick. But FPXRF could be affected by many factors and it can only measure the element concentrations of surface. Which method we use can provide the most reliable data is an important issue. The aim of this study was to verify the reliability of FPXRF and to systematically evaluate different influential factors on measurement precision and accuracy, which can help with scientific advice for its use. We set up four experiments to determine the influential factors and assess reliability by cross validation using ICP-OES. Finally, we ensured that the FPXRF was reliable and determined the scientific advice required to use it to measure the main elements and concentrations of Linqing brick.
