Gravity investigation for detecting The subsurface basement topography Of the western part of behera Governorate, North Egypt
(
Qatar University
, 1999 , Article)
One of the most effective tools for exploration of the subsurface basement topography is the gravity method. The Bouguer gravity map of the western part of Behera Govemorate west of the Nile Delta of Egypt has been analyzed ...
Petrogenesis And Tectonic Setting Of The Vqlcanic Suite West Of Wadi Bagharid South Eastern Desert, Egypt
(
Qatar University
, 1987 , Article)
The metavolcanic belt west of Wadi Bagharid, south Eastern Desert, Egypt is geologically investigated. Petrographically, the metavolcanics are subdivided into four rock varieties namely: metaandesites, metadacite-rhyodacite, ...

A Simple Diagram For Gravity Interpretation By Gradients For A Lateral Varying Formation
(
Qatar University
, 1984 , Article)
A simple diagram is constructed for the interpretation of the gravity anomaly arising from a formation of linear density variation. The diagram can be easily used if the horizontal gradient is also known. With the help of ...
Geological interpretation of gravity data On a part at the western region of the High Dam Lake, South Egypt
(
Qatar University
, 1999 , Article)
The structural setting of the area was determined using the horizontal gradient of the gravitational field and the statistical analysis of its maximum trends. The gravitational field was resolved into its two components; ...
