The Delaware Mineralogical Society, Inc., also known as DMS, is a U.S. registered tax-deductible 503(c)(3) non-profit organization located in Wilmington, Delaware, US. Its primary purpose is to promote education in the earth sciences. DMS was instrumental in the recommendation of Delaware's official mineral Sillimanite to the Delaware State Legislature in 1977.
The Delaware Mineralogical Society was founded in 1960. Its members have professional and hobbyist interests in geology, mineralogy, paleontology, and the lapidary arts. Some members are professional scientists and educators, such as chemists, geologists, school teachers, and college professors. Students also make up a portion of the society's membership. The club hosts educational programs, field trips, and an annual show the first full weekend in March.
The monthly newsletter, The Geogram, is published every month, except July and August. The group has also published over 60 articles about specific geological topics on its website. Two of its senior members have published books on paleontology.
The Society is a member of two larger organizations: The American Federation of Mineralogical Societies, the Eastern Federation of Mineralogical and Lapidary Societies, Inc. DMS also has a service affiliation with the Delaware Geological Survey. The Society has an ongoing educational partnership with the Delaware Museum of Natural History in Wilmington, Delaware.
Delaware is a state in the northeast and Mid-Atlantic regions of the United States. It borders Maryland to its south and west, Pennsylvania to its north, New Jersey to its northeast, and the Atlantic Ocean to its east. The state's name derives from the adjacent Delaware Bay, which in turn was named after Thomas West, 3rd Baron De La Warr, an English nobleman and the Colony of Virginia's first colonial-era governor.
The Mohs scale of mineral hardness is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of minerals through the ability of harder material to scratch softer material.
Claymont is a census-designated place (CDP) in New Castle County, Delaware. As of the 2020 U.S. census, the population of Claymont was 9,895.
Amateur geology or rock collecting is the non-professional study and hobby of collecting rocks and minerals or fossil specimens from the natural environment. In Australia, New Zealand and Cornwall, the activities of amateur geologists are called fossicking. The first amateur geologists were prospectors looking for valuable minerals and gemstones for commercial purposes. Eventually, however, more people have been drawn to amateur geology for recreational purposes, mainly for the beauty that rocks and minerals provide.
Mindat.org is a non-commercial interactive online database covering minerals across the world. Originally created by Jolyon Ralph as a private project in 1993, it was launched as a community-editable website in October 2000. As of 2023 it is operated by the Hudson Institute of Mineralogy.
Delaware Valley University (DelVal) is a private university in Doylestown, Pennsylvania. Founded in 1896, it enrolls approximately 1,900 students on its suburban, 570-acre campus. DelVal offers more than 28 undergraduate majors, seven master's programs, a doctoral program, and adult education courses.
The Mineralogical Society of America (MSA) is a scientific membership organization. MSA was founded in 1919 for the advancement of mineralogy, crystallography, geochemistry, and petrology, and promotion of their uses in other sciences, industry, and the arts. It encourages fundamental research about natural materials; supports the teaching of mineralogical concepts and procedures to students of mineralogy and related arts and sciences; and attempts to raise the scientific literacy of society with respect to issues involving mineralogy. The Society encourages the general preservation of mineral collections, displays, mineral localities, type minerals and scientific data. MSA represents the United States with regard to the science of mineralogy in any international context. The Society was incorporated in 1937 and approved as a nonprofit organization in 1959.
The Geological Association of Canada (GAC) is a learned society that promotes and develops the geological sciences in Canada. The organization holds conferences, meetings and exhibitions for the discussion of geological problems and the exchange of views in matters related to geology. It publishes various journals and collections of learned papers dealing with geology.
Wilmington University (WilmU) is a private university with its main campus in Wilmington Manor, Delaware, with a New Castle street address. It was founded in 1968 as Wilmington College by educator Dr. Donald E. Ross. As of 2016, the university served a total student body of 20,522 undergraduate and postgraduate students in nearly 100 degree and certificate programs. The university's programs are offered at its main campus in historic New Castle as well as at six additional campuses in Delaware, several partnership locations in New Jersey, and a single partnership location in northeastern Maryland.
The Society for Sedimentary Geology is an international not-for-profit, scientific society based in the US state of Oklahoma. It is commonly referred to by its acronym SEPM, which refers to its former name, the Society of Economic Paleontologists and Mineralogists.
The Geochemical Society is a nonprofit scientific organization founded to encourage the application of chemistry to solve problems involving geology and cosmology. The society promotes understanding of geochemistry through the annual Goldschmidt Conference, publication of a peer-reviewed journal and electronic newsletter, awards programs recognizing significant accomplishments in the field, and student development programs. The society's offices are located on the campus of the Carnegie Institution for Science in Washington, DC.
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research is an important component of geology, although many subdisciplines incorporate laboratory and digitalized work. Geologists can be classified in a larger group of scientists, called geoscientists.
Mineral collecting is the hobby of systematically collecting, identifying and displaying mineral specimens. Mineral collecting can also be a part of the profession of mineralogy and allied geologic specialties. Individual collectors often specialize in certain areas, for example collecting samples of several varieties of the mineral calcite from locations spread throughout a region or the world, or of minerals found in pegmatites.
The Mineral and Lapidary Museum of Henderson County is a non-profit, volunteer-run museum in Hendersonville, North Carolina, United States, founded in 1997 at 400 North Main Street in the middle of the city's Historic District.
The Lapidary Journal Jewelry Artist is an American magazine dedicated to lapidary interests such as gemology, jewelry design, metalworking, mineralogy, rocks, and gemstones.
Paleontology in Delaware refers to paleontological research occurring within or conducted by people from the U.S. state of Delaware. There are no local rocks of Precambrian, Paleozoic, Triassic, or Jurassic age, so Delaware's fossil record does not begin until the Cretaceous period. As the Early Cretaceous gave way to the Late Cretaceous, Delaware was being gradually submerged by the sea. Local marine life included cephalopods like Belemnitella americana, and marine reptiles. The dwindling local terrestrial environments were home to a variety of plants, dinosaurs, and pterosaurs. Along with New Jersey, Delaware is one of the best sources of Late Cretaceous dinosaur fossils in the eastern United States. Delaware was still mostly covered by sea water through the Cenozoic era. Local marine life included manatees, porpoises, seals, and whales. Delaware was worked over by glaciers during the Ice Age. The Cretaceous belemnite Belemnitella americana is the Delaware state fossil.
