the geophysics applied to the study of cultural heritage, also known as microgeophysics, involves the adaptation of several methodologies derived from geophysics. the main adaptation lies in the more or less miniaturization of geophysical instruments, especially transducers (both transmitters and receivers), so that they can be used in small volumes of material.
contribution of geophysical methods to karst-system exploration: an overview. by r. guerin. determine sinkholes and overburden thicknesses in selected covered carbonate karst terrains (kinta valley), perak, malaysia by combining wenner e.r. tomography, geological and satellite images techniques.
essentially, as the word suggests, geophysics is the application of method of physics to the study of the earth. the rocks does not differ only by their macroscopic or microscopic properties studied field geologists or petrologists. they also differ by their chemical and physical properties.
this work describes the application of the electrical resistivity (er) method to delineating subsurface structures and cavities in kuala lumpur limestone within the batu cave area of selangor darul ehsan, malaysia. in all, 17 er profiles were measured by using a wenner electrode configuration with 2 m spacing. the field survey was accompanied by laboratory work, which involves taking
a preliminary estimate of the reserve of the marble deposit in itobe area, central nigeria was determined from both outcrop geological mapping and geophysical resistivity surveying. two outcrops (designated as mass i and mass ii) of the marble deposit occurring about 850 m apart along a ne–sw axis were identified. the areal extent, thickness and density of the marble have been used in
geophysical methods allow subsurface conditions to be examined indirectly, quickly, cheaply, and reliably with sufficient results. the methods utilize different physical properties of the earth materials to study subsurface structure. two dimensional geoelectrical resistivity and seismic imaging are two geophysical techniques which are
ii) geophysical analysis. our second aim was to do large scale geophysical analysis from 20 cm depth until 160 cm depth to find out where substantial remains of buildings can be detected and where areas of refill and previously undocumented excavations were situated. iii) documentation of all antique surfaces.

by both methods as well as those unique to each method. resistivity profiles also assisted in mapping the spatial distribution of different geologic units. borehole geophysical log data, obtained a year earlier, were integrated with the surface seismic data and provided key information for deciphering complex reverse fault structures.
with the possibility of covering a larger volume of investigated soil and rock, geophysical methods have overcome the discrete nature of destructive investigation methods. however, the application of geophysical methods requires specific knowledge and experience on data acquisition, analysis, and interpretation, because the obtained solution may not indicate unique soil and rock
the ben ezra synagogue or el-geniza synagogue or the synagogue of the levantines, is located in the coptic section of old cairo area. it is considered the oldest synagogue or jewish temple found in egypt represents cultural heritage of outstanding universal values. it suffers multiple environmental, geotechnical and earthquake hazards. the integrated geotechnical and geophysical
the estimation of lithology from multiple geophysical survey methods needs to be addressed to develop advanced tomographic methods. an initial requirement for lithology discrimination is that lithology should be discriminable from the media properties physically related to the geophysical
2015). the geophysical models are generated by either forward or inverse techniques. forward modelling uses a priori knowledge of the physical properties of the bedrock in the study area, for example, in the case of the gravity field, density. the a priori knowledge is usually gained from laboratory

physical properties of marble. grain size – medium grained; can see interlocking calcite crystals with the naked eye. hardness – hard, although component mineral is soft (calcite is 3 on moh’s scale of hardness) texture: granoblastic, granular. acid reaction : being composed of calcium carbonate, marble will react in contact with many
in our research we have applied geophysical methods for the mapping of fault systems, the identification of marble blocks in the surrounding paragneiss, and in the search for cavities within these blocks. to solve these tasks we have used geoelectrical methods in the form of pole-dipole profiling, multielectrode resistivity, and gravimetry.
the renovation project of the historic branciforte palace (16th–17th century) in palermo (italy) was owned by the banco di sicilia foundation, with the aim for it to become a multi‐purpose centre for the promotion of exhibitions and cultural events.in the context of the restoration work, a multi‐methodological and non‐invasive geophysical study has been carried out.
geophysical investigation of road failure using electrical resistivity imaging method. abstract . a shallow geophysical investigation for road surface failure using 2d electrical resistivity imaging profiling was conducted to produce an approximate model of the subsurface resistivity.

the work aimed at highlighting the ability of methods devoted to the 3d geometry acquisition of small objects when applied to diagnosis performed by geophysical investigation. in particular, two methods widely applied for small objects modelling are considered and compared, the digital photogrammetry with the structure from motion (sfm) technique and hand-held 3d scanners.
