Wanapatei Group - Anomaly Seen on this map is the Wanapatei Group -
I consider it not a meteor anaomaly but rather a
geological anomaly - 
Why would i say such a thing ?
Simply put - on the map belw owe can see a negative contour image that portrays the Wanapatei Group in a different light.
I'm seeing a distinct - resistence - a land mass that has resisted the Grenville land mass intrusion and resisted the Superior land mass.
My own eyes see a pre ripple effect and a post ripple effect.
Grenville pushes into the Wanapatei - indifferent geology - creating a land mass upheaval
and a post upheaval seen upper Wanapatei Group as an arc ripple.
Ripple pattern seen lower and upper in my minds eye - points to - Wanapatei land mass resisted the Grenville and resisted the Superior land masses.
= Ripple thrusts on either side.
A perfect answer and pattern = fractured breccia.
As for the meteor anomaly found at surface ?
I would / could pass it off as, smaller meteorites that entered our atmosphere and survived the landing.
What about the rock with - meteor particles with in - seen in former post ?
Hard ot say... and, is it really metoer remnants with in the rock ?
Here's the negative pic that shows the ripple resistences.
Which i feel expalins the faults and thrusted land masses on either side of the Wanapatei
Group and - could it be the Wanapatei land mass was of a stronger characteristic which prevented it from sucumbing to a Grenville intrusion ?
My hynch says - yes. Hence, the Wanapatei Group did not see too much alteration - rather - it survived the Grenville land mass intrusion -

Cheers....
