This research study deals with the processing and interpretation of the total Bouguer anomaly and the total count iso-radiation data for a region located in the western desert of Iraq. The research aims to delineate the approximate locations and the effective depth of faults and how does rocks radioactivity act nearby the faults. The graphical method adopted to separate the residual fields...

BACKGROUND A conventional gravimetry and electro-gravimetry study has been carried out for the precise and accurate purity determination of lead (Pb) in high purity lead stick and for preparation of reference standard. Reference materials are standards containing a known amount of an analyte and provide a reference value to determine unknown concentrations or to calibrate analytical instruments...

Airborne gravimetry is an important tool for the geodesy and geophysics communities. Able to provide medium to high-resolution measurements over large areas, it is the link between the low-resolution satellite measurements and expensive terrestrial campaigns, especially in remote areas. To explore the potential of airborne gravimetry, the Gravimetry using Airborne Inertial Navigation (GAIN) pro...

Coal mining subsidence seriously affects the mine natural and ecological environment. Leveling is the traditional method to monitor the coal mining subsidence. It is possible to monitor the subsidence by gravimetry instead of leveling based on the negative linear correlation between the gravity change and the height change. Equations are derived to monitor the subsidence by gravimetry in the pa...

Compilation of almost 200 new maximum horizontal stress (SHmax) orientations in Texas reveals a complex intraplate stress field. A large extensional stress province is associated with extensive growth faulting from northeastern Mexico to Louisiana. SHmax is subparallel to the coastline, following the strikes of the growth faults. In contrast, we observe a strike-slip/normal faulting regime with...

Surveying the Earth’s gravity field refers to an important domain of Geodesy, involving deep connections with Earth Sciences and Geo-information. Airborne gravimetry is an effective tool for collecting gravity data with mGal accuracy and a spatial resolution of several kilometers. The main obstacle of airborne gravimetry is extracting gravity disturbance from the extremely low signal to noise r...

The integration of the Strapdown Inertial Navigation System and Global Navigation Satellite System (SINS/GNSS) has been implemented for land-based gravimetry and has been proven to perform well in estimating gravity. Based on the mGal-level gravimetry results, this research aims to construct and develop a land-based SINS/GNSS gravimetry device containing a navigation-grade Inertial Measurement ...

$EVWUDFW With airborne gravimetry routinely reaching accuracies of 1-2 mGal at 5-10 km resolution, it is a challenge to perform a reliable downward continuation of the gravity anomalies at altitude. Airborne gravimetry is especially suited for geoid determination in mountainous and polar regions, due to the random, alias-free sampling of the terrain, relative to typical surface surveys. In the ...
