K. Mallick et Kk. Sharma, COMPUTATION OF REGIONAL GRAVITY-ANOMALY - A NOVEL-APPROACH, Proceedings of the Indian Academy of Sciences. Earth and planetary sciences, 106(1-2), 1997, pp. 55-59
A new scheme is put forward based on the shape function concept of fin
ite element approximation to compute regional gravity anomaly. The uni
queness of this approach is that excepting eight (or twelve) discrete
gravity measurements coinciding with the eight (or twelve) nodes of a
quadratic (or cubic) isoparametric element superimposing the map space
, often very large, no other observed gravity data are invoked to comp
ute the regional. Tests on two Bouguer gravity fields, an oil prospect
and a rift valley confirmed better resolution by this approach. This
technique is straight forward, uses simple mathematics to be easily au
tomated and yields repeatable results.
