Bouguer anomaly nap o f Shithatha area had been stu d ied q u a l i t a t i v e ly and q u a n t it a t iv e ly ( a f t e r naming top ograp h ic and g r a v im e tr ic survey and a l l the n ecessa ry c o r r e c t io n s ),
several
q u a n tit a t iv e methods been a p p lie d namely, G r i f f i n method, Second v e r t i c a l d e r iv a t iv e , frequen cy a n a ly s is , downward and upward a n a ly t ic a l c o n tin u a tio n ,
f i n a l l y the t r i a l and e r r o r cu rve-
mat cliin g. The q u a n tit a t iv e methods show two s e ts o f fa u lt s .
The f i r s t
s e t i s trending N-S, and the
second set i s tre n d in g E-W o r ENE-'ffSW, the two s e ts o f f a u lt s rep resen t sh allow fa u lt s r e s u lte d and a ffe c t e d by the presence o f d eep-seated f a u l t s in the area th a t o f A b u -J ir f a u lt and Inman f a u l t .
The q u a n tit a t iv e r e s u lt s o f th ese
two s e ts show th a t the upthrow b lock depth ranges
187 between 41 to 122 m.» and the downthrow block depth ranges between 241 to 1551 m ., whereas the dip of these sets of faults ranges between 61°to 85°E.
The Bouguer anomalies as well as the
other interpreted methods show a displacement of the N-S trending anomalies which, may be due to the precance of KE-SVY trending fault.
The
regional studies of the gravity field chow the prcccnce of a fault at a depth of (0.9 - 1.0)I-.i., with a throw of (2 - 2.2)Km ., v.hich nay be related to faults of deeper origin. GEOGRAPHY AND PHYSIOGRAPHY OP SHITHATHA AREA: Shithatha area is situated within the limits of Karbala Govemate and it is located about 88 Ems, south-west Karbala.
The area"under p investigation is about 108 Em and is bounded by latitudes 32° 35' 00” - 32° 41* 47” N and longitudes 43° 18* 49” - 43° 25* 24” E. Geomorphologically Shithatha area lies id thin the limits of the lower wadi an province 'Parsons,
1955).
It lies in flat area coverd
y lower Pars formation which is a series of imestone and gypsum, Pig ( 2 ) .
Tectonically the
ivestigated area i3 located in the stable and istable shelfs of the Arabian platfonn as fined by Buday (1973).
