Album 5 - Shatter Cones & Special Evidence
Shatter cones and sharply angular rocks at the dig site
Shatter cones around the yard and on the mountain
These shatter cones, some of which are cometary fragments, are from the point of impact in the
small circular structure. They are sedimentary rocks of various lithology and so most develop
cleavages as oppose to the “horse tail” markings commonly seen on shatter cones develop in
metamorphic lithology.

Glass-like carbon fragments with crustal evidence of experiencing high heat show areas dotted with tiny luminescent crystals. Glass-like carbon is
covered in more detail in the Impact Melt section (photos 1 & 2). Transparent to semi-transparent crystals found mid-center of the small impact
structure. As there as many faces of different sizes and shapes on each side of the crystals, it is difficult to discern a basic shape on which to base the
crystals’ structures. The faces do have similarities in shape and being unfinished in form to the layers seen on the glass-like carbon. One of the
crystals has an indentation similar to those in the glass-like carbon. Quite possible, they are lonsdaleite__ the diamond that form under extreme
pressure and heat generated by an impact. Covered in High-pressure Shock Metamorphism section (photos 3 - 5).
Magnetic fragment of the comet with the appearance of Carbonado diamond. The black diamond outer surface shows melt flow on one side. The
other side, made up of small black crystals, has flow-like transparent material that is part colorless and part orange from rust (photos 1 & 2). Close-ups
of the Carbonado diamond surface (photos 3 - 5).

Group of magnetic grains, mini tektites or glass bombs in several cm sizes and different shapes. The group includes glass
spherules said to be high in titanomagnetite; glass sphere of different colors; carbon spherules said to contain nanodiamonds
and melt drops of different shapes.
The grayish and grayish-white rocks are not limestone. Considered impure, limestone in the area is mixed with marl aka
mud (as in limestone and marl), with what appears to be fish bones and carbon. Pure limestone is not to be found within
100ft of the surface in this area. Further, these rocks are black... with a thin grayish-white coating. The black under the
grayish-white coating has the appearance of "hornsfel", a baked rock that forms from shales __ pseudotachylites__
covered in the High-temperature Impact Melts section.
