GENERAL
INFORMATION ABOUT THE LOCALITY: |
|
This exciting find was made several years ago, quite by accident. The
tendency for specimens from this find is to form as elongated, single
tubes, sometimes slightly curved, but most often fairly straight down
the length of the tube. Branches are uncommon. The finder was kind
enough to provide the accompanying photos of the dig site. These
fulgurites were recovered from a sandy area where, in at least one case,
an excavation more than 10 feet deep was made in order to recover the
entire fulgurite! |

OUTSIDE
SURFACE: |
|
Form: |
Fairly straight,
to slightly curved down the length
of
the specimen, usually equidimensional, tubular. Small, secondary
branches are uncommon. |
|
Color: |
Light gray. |
|
Texture: |
Fairly smooth,
without ridges or large rocks attached. |
|
Sand
Granules: |
Small bits of
unfused Quartz sand, and tiny fragments of white
Feldspar are attached. |
|
GLASSY
INTERIOR: |
|
Color: |
Very pale “bottle-olive green” color is the normal. Rarely, specimens
with charcoal-black glassy interiors have been recovered. |
|
Texture: |
Where the
fulgurites are tubular and open, the texture of the glass is very smooth
and shiny. |
|
Bubbles (Gas
Pockets) Present: |
Numerous,
ranging from microscopic to 3/8” in diameter on some of the very large
specimens. |
