Sylvania Minerals Quarry

armstrong
Sylvania Minerals is a sandstone and limestone quarry located in the Village of South Rockwood, in north east Monroe County Michigan.

The quarry and plant began operations in 1998, and operates on a 600 acre site. The quarry mines clay, dolomitic limestone, and sandstone. The clay is used for a variety of land balance earth work projects and landfill applications. The sandstone is a high purity silica sandstone that is used for the manufacture of glass. The dolomitic limestone is used to produce a variety of construction aggregates used in road construction and pavement.

Geology

Exposed in the Sylvania Minerals quarry is Pleistocene glacial till, sandstone of the Devonian age Sylvania Sandstone Formation, and dolomitic limestone’s of Devonian and Silurian age.

The glacial till lies on top of the underlying bedrock, and was deposited during the last glaciation. As the glaciers began to retreat (melt) 25,000 years ago, they deposited a thick layer of material on top of the bedrock called glacial till. The till is predominantly clay with sand, pebbles, cobbles, and the occasional boulder. Whatever was entrained in the ice sheet, which was up to two miles thick at its maximum thickness, was deposited on the bedrock as the glaciers melted.

The sandstone under the till is the Devonian Age Sylvania Sandstone. The formation was deposited on the margin of a large epicontinental sea that inundated the middle of the North American Continent 380 million years ago. The sandstone is made up of well sorted washed quartz sand, sediments typical of shoreline and eolian (sand dune) environments.

Underlying the Sylvania Sandstone is the Raisin River Dolomite, which is the formation that is mined for construction aggregates in the Sylvania Minerals quarry. The upper unit of the Raisin River Dolomite is a cherty dolomitic limestone which is generally 100 feet thick in the quarry. The lower unit of the formation is also approximately 100 feet thick, and is made up of dolomitic limestone largely devoid of chert. The sediments that make up the formation were deposited in a shallow marine environment that covered Michigan 410 million years ago.

Some interesting fossils and minerals are occasionally found in the quarry. The most common minerals are calcite and celestite. Fossils include coral, brachiopods, bryozoans, and the rare trilobite.

Friends of Mineralogy

Explaining Friends of Mineralogy

FRIENDS OF MINERALOGY (FM):  Mission Statement and Affiliations

WHAT IS FRIENDS OF MINERALOGY?
Friends of Mineralogy (FM) is a national organization of professional and amateur mineral collectors, founded in Tucson (AZ) on February 13, 1970.  FM operates on a national level and also through seven regional chapters.   FM is comprised of professional mineralogists, mineral museum curators, and amateur collectors who share a love of mineral specimens and the desire to promote understanding and appreciation of mineralogy and geology.  Anyone who shares those interests may become a member of FM.

 

FRIENDS OF MINERALOGY MISSION STATEMENT:
FM’s objectives are to promote, support, protect, and expand the collection of mineral specimens and to further the recognition of the scientific, economic, and aesthetic value of minerals and collecting mineral specimens.  FM also holds as important the development of positive relationships with landowners and mine operators and is committed to safe collecting.

 

FRIENDS OF MINERALOGY ASSOCIATIONS:
The Friends of Mineralogy is affiliated with the American Geosciences Institute (AGI) and the Mineralogical Society of America (MSA), as well as with Rocks & Minerals and the Mineralogical Record magazines.  FM is co-sponsor with the Tucson Gem & Mineral Society (TGMS) and the Mineralogical Society of America (MSA), of the annual Tucson Mineralogical Symposia.  Among its activities it also sponsors awards for best articles each calendar year in The Mineralogical Record, Rocks & Minerals and extra Lapis English and gives special recognition at the February Tucson Gem and Mineral Show for educational displays that help explain an aspect of mineralogy.  Both of these magazines provide FM space and publish news of its activities from time-to-time.  FM in turn supports these magazines in various endeavors.

 

FRIENDS OF MINERALOGY COMMITMENT TO EDUCATION:
FM members do not just go into a quarry to collect nice specimens to take home.  Our members like to know what they are collecting and the geologic environment in which it formed.  Considering this, every field trip can be a learning experience for our members.  We share this information and specimens with quarry personnel so that they can help educate young students in their area.  The result is that the quarry can impact science education in their area by affiliations developed through FM field trips.  At the same time, quarry personnel often share information with us about their operation, whether their quarry mines materials for cement, ag-lime, decorative stone, or road aggregate.  With information coming from both sides – the geology of the field trip – and the products of the quarry’s operation, all parties can share in the learning experience.  FM also works closely with the Ohio Earth Sciences Teachers Association, which provides mineral samples for teachers.  It is through our commitment to education and safety that we hope to develop positive relationships with host quarries.

 

FRIENDS OF MINERALOGY COMMITMENT TO SAFETY:
A majority of our field trips are to quarries where the host asks for MSHA hazard and safety training certification.  Therefore, only those members who have completed an MSHA hazard and safety training refresher course within the past year are permitted to attend field trips where MHSA certification is asked for.  If, on a given trip, a collector finds nothing worth taking home (which is rare!), when that collector leaves a quarry in good health, that collector has had a successful day.  An important goal is to have everyone in our membership employ safe collecting procedures and follow the directions of our host.  We feel that, because our commitment to safety is so important, this is an important first step toward developing positive relationships with our host quarries.  In addition, through a program initiated by one of our members who is an associate MSHA instructor, senior Ohio Department of Natural Resources geologist, and veteran collector, we are working to standardize MSHA training tailored for collectors throughout the region of the FM Midwest Chapter (IL, IN, KY, MI, MO, and OH).
