Rock Collecting in Georgia

Filed under: General Rock Collection — tdunevent @ 6:36 am

Great South Gems & Minerals will be holding an open-house on Saturday, April 26, 2013 and Ray Hill will be giving a demonstration and class on rock collecting in Georgia.  This event is open to the public and anyone interested in rock collecting, lapidary work, fossils, or other interest in the rock collecting field will have a great time at this open-house.

For many years Ray has traveled nearly all of Georgia and has become very knowledgeable rock collecting locations throughout the state.  Ray has collected agate, quartz crystals, jasper, kyanite, pyrophyllite, limonite, goethite, fossil crinoid stems, trilobites, brachiopods fossils, turritella fossils, large clam shell fossils, and others rocks, minerals, and fossils in Georgia, and has studied the geography of the state.

Pronounced “nice”, this is an excellent specimen of the process referred to as Gneiss. Many years ago at one of our local rock club meetings we had a professor from the University of Georgia speak to us about “Gneiss” rocks. He explained that as “birds of a feather flock together”, the process Gneiss is one in of which like minerals go through a metamorphic process and come together in layers or bands. I thought that was a pretty good explanation.

Wikipedia states that Gneiss rocks are “common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks.” This process takes place deep within the earth where time, heat, and pressure causes minerals of a type to come together.

Gneiss is coarser than schist and has distinct banding. This banding has alternating layers that are composed of different minerals. The minerals that compose gneiss are the same as granite. Feldspar is the most important mineral that makes up gneiss along with mica and quartz. Granite is commonly used by man as paving and building stone. Ray and his grand-son Spencer collected this material recently.

Fossil Pine Cones

Filed under: Fossils — tdunevent @ 8:39 pm

Great South Gems & Minerals just received thirty fossilized pine cones from Morocco. These specimens were found in the western Sahara desert in Morocco.  The fossil pine cones are from the Eocene period dating back 33 to 55 million years old.  On some of these specimens great detail of the pine cone, including the seeds are visible.  These fossilized pine cones belong to the conifer family.

Rutilated Quartz Points

Filed under: General Rock Collection — tdunevent @ 7:36 pm

We just received a shipment of beautiful rutilated quartz crystal points from Brazil.. Each of the crystals have been cut with a flat base to where the crystal will stand up, all of them have been polished. Some of the best rutilated quartz crystals we have ever had. This batch of crystals are mostly clear to smoky with golden color radiating rutile fibers inside them. Rutile is a mineral composed primarily of titanium dioxide. Rutile has among the highest refractive indices of any known mineral and also exhibits high dispersion. Natural rutile may contain up to 10% iron. Rutile derives its name from the Latin word rutilus, red, in reference to the deep red color observed in some specimens when viewed by transmitted light.

Rutilated quartz is prized by rock collectors, the metaphysical crowd, and is used as gemstones. Cabochons cut for a good quality rutilated quartz sell for upwards of $20.00 per carat.

Rock Collecting at Preston, Georgia

Filed under: General Rock Collection — briangsb @ 1:44 pm

Spencer, my 8-year old grandson, Ramona Beshear, my scientist rock-buddy and I went down to between Preston and Buena Vista, Georgia yesterday on a rock collecting trip.  It was an absolutely gorgeous day.  The weather was perfect.  Ramona and I had been to this location a couple of time, back some years ago.  The collecting area is on a dirt road named Slaughter Road out in the country.  Spencer didn’t do a lot of collecting but had a ball going up and down the red clay banks, counting how many deer tracks he could find, throwing rocks and sticks and in general acting like an 8-year old boy.  He stated on the way back home “Pawpaw, that was the best trip ever!”

Ramona and I both have about as much of the material from this location as we need and mainly went there looking for fossil root casts and goethite pieces with sea-shell imprints in them.  These are not plentiful at this location but they are there.  I found one nice fist-size specimen of goethite that has shell imprints, called trace fossils.  The imprints this specimen are of a thumb-nail size seashell, an imprint of a gastropod type shell and an imprint of a cephalopod.  This was the prize of the day.

Ramona and I both found lots of fossil root cast that ranged from half inch to over one inch in diameter and from one-inch long to about three inches long.  These fossils are composed of a dark brown limonite, with sand grains bonded to the outer surface.  It’s my guess that the fossils found here are at least cretaceous age, or about 100myo.  The root cast were formed when a tree died and rotted away.  The roots in the sandy soil would have deteriorated away, leaving a mold-like cavity where the roots had been, and then the iron rich sediment would have seeped into the cavity, taking the shape of the cavity where the root had been and then hardening into the limonite stone.

The goethite found at this location is very plentiful.  It is scattered in the ditches, road-way and banks for a mile or two up and down the dirt road.  Seasoned rock collectors go to this locations and look for goethite specimens that have areas with mirror-like, glassy, surfaces, much like the botryoidal hematite specimens coming from Morocco.
The real glassy material is not plentiful but it is there.  Seems like every time it rains here, there is more of the material exposed along this road way.

Goethite, pronounced “ger-tite”, is a principal ore of iron, along with limonite, hematite, and magnetite.  It has the same chemical formula as limonite, which can be bright yellow.  Yellow limonite is called ochre, which has been used as a pigment for paint and cosmetics throughout history.

I know I got more enjoyment from this trip than did my two companions, although Ramona and Spencer also had a great time.  It’s a true pleasure to be with others on a collecting trip when they are thrilled to be there!

We’ve just ran an ad in “Rock & Gem Magazine” for a rock tumbling kit that includes Lortone Rock Tumbler, all four stages of tumbling and polishing grit, and two pounds of semi-precious gemstones.  This will be one of our Christmas Sale items.  Kids of all ages are going to love this item.   Great South Gems & Minerals, Inc.

Specimens of CAVE ARAGONITE just in

Filed under: Minerals Wholesale — Tags: , , , , — josegsblog2250 @ 6:05 pm

Aragonite, CaveNEW: killer specimens of CAVE ARAGONITE just in.  Beautiful snow-white specimens.  Looks like small trees covered with snow.  Really nice material.  From Mexico.  White sparkling crystallized aragonite specimens that formed at the roof of a cave or cavity like a stalactite. Cave aragonite is a carbonate mineral, the stable form of calcium carbonate.  Aragonite is a mineral normally found in pearls and in some animal shells.
