2016 UPDATES of MY AMATEUR IMPACT CRATER/STRUCTURE EXPLORATIONS

by: Charles O’Dale

DECEMBER

• Prince Edward Point, Ontario  – UNDERWATER EXPLORATION

This image illustrates dark material deposited in a linear manner in a natural groove in the bedrock by wave motion. This explains the “dark” pseudo-crater rim that I saw from the air.

NOVEMBER

• Charles O’Dale – CV  – Presentation in the DEN OF LOR

OCTOBER

• Chicxulub, Yucatan Peninsula 

Renne, Paul R.; (et al) Jan (7 February 2013). “Time Scales of Critical Events Around the Cretaceous-Paleogene Boundary”. Science 339 (6120)

SEPTEMBER

• IDENTIFYING IMPACT STRUCTURES  – SHATTERCONES

AUGUST

• Chicxulub, Yucatan, Mexico  – FUTURISM POSTER

JULY

• Panther Mountain, USA – JOINT EROSION

The joints were spaced about a foot apart there, some 10 times closer than jointing elsewhere in the surrounding rocks. That’s what governed the circular course of the creeks – water will preferentially erode away rock where it’s weaker and so areas of the bedrock with more frequent jointing will eventually form creek valleys..(Hudson Valley Geologist)

• Barringer Crater, USA – GRANULAR ZIRCON REVEALED

Transformations to granular zircon revealed: Twinning, reidite, and ZrO₂ in shocked zircon from Meteor Crater (Arizona, USA) Aaron J. Cavosie, Nicholas E. Timms, Timmons M. Erickson, Justin J. Hagerty and Friedrich Hörz

• Carolina Bays, USA –

JUNE

• Jocko River Spring Structure –

I am balancing half way up the crater rim and holding a birch branch so it hangs vertical. Referencing the vertical branch with the one placed on the rim, the angle is ~50°.

 

MAY

• Sudbury, Ontario – CHEMOSTRATIGRAPHY & ZIRCONS

Differentiated impact melt sheets may be a potential source of Hadean detrital zircon – Gavin G. Kenny, Martin J. Whitehouse and Balz S. Kamber

• Chicxulub, Yucatan, Mexico – DRILLING PROJECT

• Marmora Mine, Ontario Canada –

Marmora Mine 520 X 365 metres and 215 metres deep (1700 feet X 1200 feet and 700 feet deep).

 

 

APRIL

• Parry Peninsula, NWT 

The 160 Km diameter Parry Peninsula structure is a possible central peak impact crater.

 

 

MARCH

• Younger Dryas Extinction – LONSDALEITE

Nanosecond formation of diamond and lonsdaleite by shock compression of graphite (Kraus et al 2016)

• Manitou Islands, Ontario – GEOLOGICAL UPDATE

Aeromagnetic map of the Manitou Island complex (from ODM-GSC 1965c)

 

 

 

• Wanapitei, Ontario – BOLIDE IDENTIFICATION AND IMPLICATION

Update: Evidence for a second L chondrite impact in the Late Eocene: Preliminary results from the Wanapitei crater, Canada. R. Tagle1 (et al) 2006
