Langeo/BTSK is specialized in the geophysical exploration instruments, as DC resistivity/ip meter, 2D/3D multielectrode imaging system, proton magnetometer, digital seismograph, transient magnetic system(TEM), highpower induced polarization system and so on. Those all widely apply for different geophysical explorations as underground water, mineral source, city engineering, geothemal
Once the geophysical method suite was optimized, the investigation program was streamlined. Although this investigation program developed over time, the multiple objectives of investigation remained focused on: 1. Determining the presence or absence of a significant groundwater flow horizon just below auger refusal depths; 2.
Two different geophysical methods were applied, namely, electrical resistivity tomography (ERT) (Ward 1990) and electromagnetic terrain conductivity (ETC), using the Syscal Jr Switch 48 channels by IRIS and the EM31MK2 instruments by Geonics Limited, respectively. Resistivity profiling and electromagnetic mapping have been carried out in grids of 8 #215; 20 and 20 #215; 20 m, respectively.

Geophisical exploration is the (mostly) noninvasive investigation of subsurface conditions in the Earth through measuring, analyzing and interpreting physical fields at the surface. Some tools employed by geophysicists, such as core drilling, are also employed by geologists using
13/10/2020#0183;#32;THG designed a geophysical survey to investigate the bedrock using 2D electrical resistivity imaging, or electrical imaging (EI). Considering the site geology (weathered sandstone and limestone) and surface conditions, EI was selected as the

Landslide deformations involve approximately all geological materials (natural rocks, soil, artificial fill, or combinations of these materials) and can occur and develop in a large variety of volumes and shapes. The characterization of the material inhomogeneities and their properties, the study of the deformation processes, and the delimitation of boundaries and potential slip surfaces are
1/1/1974#0183;#32;As technology and the quality of instrumentation advance, there is abundant justification for periodic reassessment of the foundation geology and subsurface hydrology by geophysical, rock mechanics, and borehole investigations and installa tion of modern, improved monitoring devices which will foretell the need for corrective measures well in advance of possible foundation disintegration and

A poorly lithified and often glauconite rich sandstone rests upon the Precambrian bedrock. The glauconitic sandstone has been formed in a marine environment with relatively high water levels (Kornf#228;lt et al. 1978), and it is overlain by the Cretaceous transgressions and regressions occurred during the late Cretaceous, and the limestone consists to a large degree of carbonate
They have also been used to locate sink holes and caverns in limestone areas. The most common type of gravity instrument is the gravimeter, which measures the direct effects of the pull of gravity on a mass suspended by a delicate spring. Changes in the length of the spring are related directly to the vertical intensity of the gravity field.
CPT data has been correlated to soil properties. Sometimes instruments other than the basic CPT probe are used, including: A piezocone penetrometer probe is advanced using the same equipment as a regular CPT probe, but the probe has an additional instrument which measures the groundwater pressure as the probe is advanced.
A geophysical survey for limestone deposits was carried out at Nkalagu of Ebonyi State in foundations and walls where a high polish is not needed. instrument used for the survey is the ABEMTERRAMETER with the Schlumberger... Read more
