ABSTRACT: The area covered by this study is the county of
Kakobola and its surroundings. Previous studies show that those related to the
study of depths by the gravity method, using other techniques, are not always
carried out until now. The main goal of this article is the gravimetric
characterization of our area by other approach. The interest is not only to map
the lineaments and to know their dip, but also to estimate the depths of these
different anomalies. The methods used for this study are the first total horizontal
derivative (FTHDT), tilt angle (TA),
analytical signal (AS) and horizontal gradient magnitude (HGM). The processing of the complete
Bouguer anomalies (CBA) data was done mainly
through software. Data analysis using the semi-finished body depth
method shows depths ranging from 7.49 m to 224.6 m. Data analysis using the AS method shows values ranging from 41.7 mGal/m to 510 mGal/m. The fractures and/or geological contacts in our
study area show dips ranging from -73.73°to
68.16° and North-South orientation according to the tilt angle method.
The FTHDT shows several lineaments, a NE oriented fracture of Kakobola and low
dip values which suggest a tabular structure of the subsurface in our study
area. According to the HGM, the study area shows several preferential
directions of fractures and/or geological contacts whose the most frequent
directions are the NNE-SSW and WNW.
