Diamonds were discovered at this location in 1906. Now a fee-based collecting site.

Four major rock types occur: magmatic lamproite (with mantle and crust-derived xenoliths); marr epiclastics (largely sandstone); lamproite lapilli tuff (phlogopite-rich); and lamproite breccia tuff. These last two types are the source of most of the diamonds recovered in the visitor area.

Haggertyite is present as microscopic hexagonal plates in the alteration zones of xenoliths in Prairie Creek lamproite.

The Prairie Creek Lamproite is Early Cretaceous (106 mya) in age.

Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.

Cretaceous
66 - 145 Ma



ID: 2840602
Igneous rocks

Age: Cretaceous (66 - 145 Ma)

Description: Includes undifferentiated altered sedimentary rocks of Paleozoic age at Granite Mountain, Pulaski County, and Mufreesboro, Pike County. Acid to intermediate - Nepheline syenite complexes at Magnet Cove and Potash Sulfur Springs, stocks at Granite Mtn., explosion breccias, and dikes and sills (principally trachyte,tinguaite, phonolite, some ranging from syenite to diabase). Basic to ultrabasic - Lamproite pipes (Murfreesboro, Pike County) and dikes and sills (principally lamprophyres of fourchite, ouachitite, and monchiquite).

Comments: Alkalic ring dike igneous complexes: Magnet Cove (Hot Spring County)-core of carbonatite-ijolite, inner ring of alkalic extrusives and outer ring of nepheline syenite; Potash Sulfur Springs (Garland County)-mafic alkalic rocks, carbonatite, nepheline syenite and syenite. Both intruded during Mesozoic time into Paleozoic shale, sandstone and novaculite. Original map source: Haley, B.R., Queen, J.E., and Green, G.N., United States Geological Survey Special Publication, 2000, The Geologic map of Arkansas, scale 1:500,000.
