President’s
Message
I wish to thank all those
who attended and
assisted at the annual
picnic and auction on
Saturday, April 18. It did
not rain, we had a
delicious variety of food,
and members were
generous in their
response to the auction.
It also helps to reduce
some of our inventory at
the workshop and make
room for future donations. Thank you to Bill,
Cheryl and Rick, Tom
and Eivor, Emily and
Josh.
Members have been
producing some beautiful
work in recent classes
and open shop. We
always hope they will
bring their finished work
to show and tell so the
rest of us can appreciate
them.

Just For Kids
The Rock Cycle
Rocks are the most common material on Earth. They are naturally occurring aggregates of
one or more minerals.
Rock divisions occur in three major families based on how they formed: igneous, sedimentary,
and metamorphic. Each group contains a collection of rock types that differ from each other on the
basis of the size, shape, and arrangement of mineral grains.
The rock cycle is an illustration that is used to explain how the three rock types are related to each
other and how Earth processes change a rock from one type to another through geologic time.
Plate tectonic movement is responsible for the recycling of rock materials and is the driving force
of the rock cycle.

May’s Mineral— Fairburn Agate
What Is A Fairburn Agate?
Agates, in nodules and geodes, are some of the most
popular varieties of silica.
Agate forms under sedimentary conditions.
Whitlock (1946) states as an analogy that the quartz
varieties are like six-sided snow crystals, and agates
are like rounded icicles of freezing water. Agates
consist of alternating layers of fibrous chalcedony
with circular to semicircular layers, patterns, or
bands like rings of targets. These layers may be
composed of different thicknesses and colors. The
layers are usually concentric and parallel to the walls
of the rock cavity in which they are deposited. Fairburn agates are formed in this way.
Fairburn agates are noted for their strikingly contrasted, thin bands of wonderful natural colors
(Sanborn, 1976). Roberts and Rapp (1965) state
that the color patterns are generally yellowish-brown
with narrow opaque white bands, or dark red with
white bands. However, another beautiful combination shows salmon-pink bands alternating with white
bands. Other colors included in these agates are
black, yellow, grayish-blue and milky-pink.
These agates were originally named after a prolific
locality 10 miles east of Fairburn, South Dakota, in
the southern Black Hills area. According to Roberts
and Rapp (1965), Fairburn agates occur in a broad
elliptical belt extending from Creston in Pennington
County, South Dakota, to near Orella in Sioux County, Nebraska, with the maximum width approaching
15 miles near Red Shirt, South Dakota. According to
Fritzsch (S.D. School of Mines and Technology, personal communication, 1993), the area is more restricted (Figure 1). The Fairburn agate fields cover
thousands of acres of very stony land and most of it
is rugged terrain, well decorated with cactus, weeds,
and cedar trees (Zeitner, 1964).

What Is The Value Of Agate?
The Fairburn agate was designated as
South Dakota's state gemstone on February 11, 1966. In the literature, Fairburn
agates are reported as quite scarce, and
highly prized by collectors (Campbell and
Roberts, 1985). The price of a Fairburn
agate ranges up to $150, depending on
the size and quality of the geode (Eric
Fritzsch, Geology Museum, South Dakota
School of Mines and Technology, personal communication, July, 1993). As with
other agates, a larger Fairburn agate is
not necessarily a better-quality agate. Agates are primarily used as decorative
pieces, as mineral specimens, and in lapidary work.
