MyRock

Found on the bank of the Sabinal River, south of Hondo Texas in 1989

Is it a Meteorite?

SIZE: 5.9" wide, 4.0" tall, and 3.75" thick

CAUTION:

Meteor Identification page says:

"...holes or 'vesicles' were produced by bubbles of gas that formed in the magma as it was erupted. If you find a rock that is porous or contains vesicles it is a terrestrial rock.

The rock is not magnetic at all.

VOLUME = 800 cc [measured in graduated 2000 ml beaker]

WEIGHT: 5 pounds 6.5 ounces OR 86.5 ounces OR 2,453 grams [measured on a digital scale]

DENSITY = grams per cubic centimer

DENSITY = 2,453 grams / 800 cc = 3.06

The streak test on unglazed procelain produced a black streak.

Found on the sandy banks of the Sabinal River,


west of Ranch Road 187
6.77 miles south of Sabinal Texas
236 miles west of Houston

Latitude-Longitude 29.21990, -99.46359

The Sabinal River originates 48 miles north

Only the green-ish top was visible in the Sabinal river bed. The top of the rock was exposed -- mostly buried in a muddy algae pool at the edge of the bank. There is a green slime on the top part of the rock that must have been exposed to the algae for a long while. The bottom 2/3 of the rock was buried in harder mud. Notice the vertical color change from maroon to green in the top latitudes.

There are no vesicles on the bottom suggesting that the rock was broken along the bottom of the left-front-right images. This bottom view could be the interior of the broken heart shaped disk.

See "Formation of vesicles in asteroidal basaltic meteorites," 2006 Earth Planetary Science Letter

Whites streaks like the one shown on the 'FRONT' view continue very sparsely in the up-down direction. They appear in the 'BOTTOM' cross-section several white dots dispersed in an otherwise consistent gray solid.

My rock has a very similar structuure to (2) and (3) above (small vesticles and non-metallic)

If #3 rock above 113 gm = $30,000 then 2,453 gm = $ 651,000

DENSITY COMPARISON -- MyRock has 3.06 density and falls into three categories (highlighted in gray below) -- that compose 58 % of all meteorites.

The white dots are the white sparse streaks seen in the FRONT view -- but here in cross section they appear as white dots. There are about ten dispersed across the BOTTOM view.

There are only five or six very small vesicles in this BOTTOM view. There are many darker small gray circular bodies that are not vesicles. They have no depth.

Compared to the other views, the BOTTOM view is different. It is the inside view of a broken disk.

There is only one brown larger brown body that is shiny and reflects light
