Ann: Mineralised carbonatites intersected over 3.5km -West Arunta, page-161

Good pick up @Wack

Updated regional tenements with these and to the north. Also geology doesn't stop at state lines so added NT tenements (slightly different system to WA so may have missed some - all shown in NT are classed as applications with much of the area pegged by consulting type outfits)

Why did ENR peg these four claims?
Magnetics are not prominent - RTP? Geoview.


Processed magnetics show more detail with the first vertical derivative.



Is P2 also along the Elephant Island fault?
Parallel fault structure to north? mostly WA1 application area.
Both magnetic images suggest, to me, the cover is much deeper to the north (and south of the original ENR tenements; also becomes deeper in the far east?)

Gravity


Geoview regional gravity gives a very different image to the magnetics though some structures are probably common to both. The 1VD magnetics also reflect the northerly trend seen between 5936 and 5937.
Major crustal feature sub parallel to Elephant I fault? Of interest for 5934,6 perhaps but less so to the west (35, 7)

Geology


Immediately north of the prominent magnetic ridge there is probably a down faulted zone (mainly WA1 applications). North of this and partially covered by ENR claims is a sequence of northerly striking units with local folding. Outcrop exposure is fairly good judging from government mapping.
============
Now for something esoteric - Gravity worms from NT and WA survey processing.




Not certain what the worms represent. Probably deep seated structures. Any geophysicist?
