FIELD TRIP INFORMATION SHEET

March 2007 DMC Field Trip

DMC Program of the SFMS Field Trip Committee
An Official Field Trip of KYANA Geological Society, Louisville, GA (HOST)

Day and night digs
Saturday and Sunday, March 17-18, 2007
Hickory Cane Mines
Marion, Kentucky

FEE SITE

COLLECTING:  Fluorite, smithsonite, sphalerite, cerussite, galena, hemimorphite, hydrozincite, quartz, & pyromorphite. Calcite is by far the most common mineral found, and all other minerals require some digging in
the dump to locate.

FEE: The day time digs will cost $20 and the night time digs will be $30 (this entitles you to one five gallon bucket of specimens). Admission to the Ben Clement Fluorite Museum is $ 5.

All reservations for the digs will be handled though the Ben E. Clement Mineral Museum at www.MarionKentucky.us. Or call 270-965-9257, or write Ben E. Clement Mineral Museum, 205 North Walker Street, Marion, Kentucky 42064.
Information on campgrounds, lodging, and bed and breakfasts can also be obtained from Clement Mineral Museum.

In order to fill any vacancies in the scheduled digs, left by the SFMS, after March 1, 2007 these vacancies will be open to KYANA members and any other rock hound who wishes to join the dig. While the primary purpose of
this trip is to accommodate SFMS members, the secondary purpose is to help the Ben E. Clement Mineral Museum fund its efforts in maintaining a world class fluorite collection and making it available to the public.

WHAT TO BRING:  Other than standard collecting equipment, bring plenty of water, snacks, camera, and you will need a portable ultraviolet light. Daytime collectors will need a way to check fluorescence too! Black light boxes or whatever suits you. Night time collectors will need a standard flashlight to travel to and from their cars. The time of the month was chosen because it is the dark of the moon! Short wave and broad spectrum ultraviolet lights are best. Most collectors will share their lights, but do not count on it, after all someone will need to bring a light.

Although, the temperatures have been unseasonably warm thus far, March can occasionally be quite brisk in the Ohio Valley. So be prepared to dress warmly, multiple layers works best.

MINE HISTORY:  The mines where the dig is to be conducted are located on the Commodore fault system and date back to 1901. Mine shafts on the property have produced fluorite, smithsonite and sphalerite. Other minerals
that have been found in the mine dumps include; cerussite, galena, hemimorphite, hydrozincite, quartz, & pyromorphite. Calcite is by far the most common mineral found, and all other minerals require some digging in
the dump to locate.

The Rock Shaft dump comprises most of the material at this mine site. The Rock shaft was completed to the depth of 240 feet. From 1924-25 some 8,000 tons of smithsonite was removed from the Rock Shaft. The Maddox shaft
sunk in 1941-42 was completed to remove approximately 215 tons of "gravel spar" (fluorite). A crosscut was made from the Maddox shaft to the Commodore Fault and in 1945 a vertical raise was cut up though the Commodore Fault zone. This raise is known as the Yandell shaft. Mud, gouge, calcite, fragments of fluorite veins, sphalerite and galena were noted (R. Trace, 1954). There is an open shaft on the site which is surrounded by barbed wire.

The most common fluorescent mineral is calcite which glows a soft to bright pearly white. There are other colors other than white, but they are fewer in number. Of particular note are specimens of sandstone which glow a coral
pink to a bright red in either short wave or broad spectrum ultraviolet light. There are also specimens which glow various shades of pale yellow and bright blue. Please note: that included in the spoil are fragments of mortar and concrete which will also fluoresce. The concrete and mortar was made from rock from the mine.

Charles Oldham a retired professional geologist from the Kentucky Department for Surface Mining with over 30 years of mining experience will be your KYANA host, along with his sidekick Betty Hansel and as many KYANA
members as we can carry. Charles has been collecting minerals and fossils for over 50 years, starting at the age of five, when his father gave him a "gold ore" specimen from California. In later years his father (a retired naval engineering officer) asked Charles why he became a geologist and not an engineer. Charles replied you should have given me a micrometer and not a rock!

"Field trips are open to all members of associated clubs of the DMC program of the SFMS Field Trip Committee and to all members of SFMS member clubs who have provided their membership with SFMS liability insurance.  Because of insurance requirements, members of the GENERAL PUBLIC are NOT invited on this or any DMC program field trips!"
 
DMC Program / SFMS Field Trip committee's purpose:
To collect field trip information from it's member societies; schedule and coordinate field trip dates; disseminate field trip information to all member clubs so that each member society may publish this information as one of their "official" scheduled field trips.
