Green and pinkish minerals matrix, some silver-colored metal seen on similar fragment and gold color metal or mineral.
Close up showing suspended gold color flecks on right.
Slightly left from top center are gold color flecks within greenish and redish matrix. Do not know what is shown on right at upper right.
String of gold flecks upper left from top center in the rock's matrix.
Rev. of darker magnetic rock fragment
Darker fragment - close up
Darker fragment of with cloudy white melt minerals
Darker piece with cloudy white melt matrix - close up
Larger fragment of rock
A larger fragment with similarities to the above.
Plagioclase or Polysynthetic Twinning seen - forms as the plagioclase cooled. Angled to a light source, light reflects off one set of microcleaveage surfaces.
Front with silvery metal flecks, melt minerals as seen on mixed fragment and rust.
Rock with silvery metal flecks and melt mineral seen on mixed mineral fragment.
The outer portion of the above rock fragment (pic 1) shows melting while inside (pic 2) shows colors of greenish and
reddish glassy matrix. Upper right (pic 3), above center to left (pic 4) and upper left (pic 5) attempt to show suspended
gold color flecks believe to be sulphides. Objects shown on the upper right of pic 4 could be ferrimagnetic pyrrhotite.
Plagioclase Twinning captured from another fragment (pic 6). Photos (7 & 8) of another rock fragment showing what
appears to be secondary melt crust. There is an abundance of this fragment.
Close up on rock fragment with silvery metal in melt matrix.
Fragment showing silvery metal flecks, fractured vein, melt white and black minerals.
Fragment showing metal flecks in melt matrix.
Fragment showing crusty area with what appears to be graphite.
Larger fragment showing white and black melt minerals
Stone fragment with silvery metal flecks
Magnetic rock fragment showing what maybe secondary fusion crust or just melt minerals
This piece of high-metal content fragment shows a mix of glassy mineral (appears as bright streaks in the photos of both the front and reverse sides -
pics 1 & 2) and carbon chips (pic 3 close-up at bottom left). Filed section fragment shown in pic 1 along with another high-metal fragment (pics 6 &
7). The inside of the rust covered metal fragment showing bronze to golden yellow color - Osbornite. This mineral was acquired by NASA's Stardust
mission during its collection of Comet Wild 2 dust (pic 8).
Front of high metal content fragment showing possible graphite chips - dark spot areas.
High metal content fragment showing glassy melt section with plagioclase twinning and possible graphite chips - dark spots.
The outer portion of the above rock fragment (pics 1 and 3) shows matted crust with various light-brown spots.
Close-ups of the surface (pics 2 and 4).
Filed rock fragment with rust, melted minerals, what maybe remnant of fusion crust (black area), fractured vein on side and silver color metal flecks.
Very difficult to remove the outer portion with a hand-held diamond file as instead of the rock being filed, the particles from the file are removed.
This group of rock fragments, although appear different from the others above, show what maybe secondary fusion crust and silver color metal flecks.
Possible remnants of graphite shown on fragment in pic 2. Effort made to file fragment in pic 3 without success.
This multicolor fragment with grayish-blue, green and yellow minerals (pics 1 and 2) is seen on the rock fragment in
pic 3. These minerals appear to be partially melted serpentine and is seen on another fragment with numerous
impact fracture veins (pic 4).
Fragment showing fractured veins and melt mineral similar to the fragment beside it.
Mixture of minerals in a fragment that appears to be partially melted serpentine. Same material seen on the rocks with the pink and green matrix above
Mixture of minerals seen on the rocks. This fragment appears to be partially melted serpentine.
high metal fragment with graphite chip in lower left
comet fragments covered with material appearing to be partially melted serpentine.
Close-up of high metal content comet material, quite possible, Osbornite!
high metal content cometary fragments or what may be the core of a differentiated asteroid.
Filed portion of high metal content cometary fragments
According to NASA’s Jet Propulsion Laboratory on its research of Comet Wild 2, a comet is an
aggregate composed of different minerals one would not find in an area composed purely of
Sedimentary rock types. [http://stardust.jpl.nasa.gov/news/news110.html]
cometary fragment with dark color minerals appearing to be carbonados with cuboid shape black diamond crystals
Perhaps this should be the pink mineral group of comets' minerals.

Pink minerals with black minerals
reverse of pic 3 showing pink and black minerals
A cometary fragment with prominent pink and black minerals
cometary fragment with alkalic igneous glassy nature
akalic igneous appearing asteroid fragment
magnetic prominent pink k-feldspar, white and black minerals giving the rock a gabbroic appearance.

A darker fragment with shatter cone shape that was picked up from the middle of the small impact structure.

cometary fragment with high metal content.

Group of comet impact melt glass, possible portions of the asteroid's crust with rounded vesicles.
Cometary impact melt material or comet material of foamy, vesicular glass.
Group of highly magnetic impact melt glass or comet material.
melt glass - glassy cinders - foamy glass from the comet impact melt or I am leaning more to this being a part of the comet as it is magnetic.
Close up of the glass melt, vesicular cinders showing the gas pockets and glass minerals.
Highly magnetic vesicular, mixture of glass and metal believe to be portions of the comet's crust. A high metal content fragment is seen on the far
right (photo 2). The aggregate of colors showing on the fragments may be indicative of the pieces being subjected to very high temperature.
Close-up on broken fragments showing glass and vesicles (photo 4). Note that the vesicles are round!
cometary fragment with glassy clast similar to those seen on alkalic igneous rocks.

Above is an aggregate of different colorful, magnetic igneous rocks believed to be portions of a comet or asteroid that hit North America on its northeast
side shortly after the withdrawal of the late Wisconsinan Glacier. The bulk of the rocks gathered are shown in the Cometary Fragments section.
