Buchwald has this to say about the unusual etch pattern of Mount Dooling:
The reason for the Widmanstatten pattern being so ill-defined is the almost entire absence of taenite and plessite fields. This is in harmony with the nickel analyses, showing 6.2% on the average. Whatever there is left of a former Widmanstatten structure is mainly seen because the 1-2 mm wide and 5-15 mm long lamellae are oriented differently from the adjacent lamellae and, therefore, display a differently oriented sheen.
