The search for a more realistic metallogenic map format, with reference to...
The format of most existing metallogenic maps is not adequate for scales of 1:500 000 or less. The major problem is the colourful out-of-scale locality symbols, which mask the... -

The age of the Mud Tank Carbonatite, Strangways Range, Northern Territory
Dates of 732 ± 5 m.y. (U-Pb zircon) and 735 ± 75 m.y. (Rb-Sr total rock) define the crystallisation age, and possibly also the emplacement age, of the Mud Tank Carbonatite.... -
