The Buckwheat workings started as the Buckwheat Mine and the Southwest Opening, both at the southern end of the Franklin orebody.
Subsequently, that portion of the orebody, at the shallow end where the two limbs of the orebody curved around and, vertically, form a "spoon" shaped basin, was excavated as the Buckwheat Pit.
This later major working obliterated the two prior workings in total.
The Buckwheat Pit incorporated areas intruded by pegmatites and featured major, vertical camptonite igneous dike intrusive bodies plus a veinlike body of vuggy dolomite (the Buckwheat Dolomite) of apparent Paleozoic age.
All of these geological features contributed to the diverse mineralogy of this locality.
This locality is within the Franklin Mining District.
The complete list of mineral species occurring within this district, as well as the official boundaries of the district, can be found under the locality file for "Franklin Mining District."

Franklin Marble

Age: Mesoproterozoic (1000 - 1600 Ma)

Stratigraphic Name: Franklin Marble

Description: White- to light-gray-weathering, white, grayish-white, or, less commonly pinkish-orange, coarse- to locally fine-crystalline calcite marble with accessory amounts of graphite, phlogopite, chondrodite, clinopyroxene, and serpentine. Contains pods and layers of clinopyroxene-garnet skarn, hornblende skarn, and clinopyroxene-rich rock. Thin layers of metaquartzite occur locally. Intruded by the Mount Eve Granite in the Pochuck Mountain area. Franklin Marble is host to the Franklin and Sterling Hill zinc ore bodies; exploited for talc and asbestiform minerals near Easton, Pennsylvania. Subdivided into an upper marble, "Wildcat marble," and a lower marble, "Franklin marble," by New Jersey Zinc Co. geologists (Hague and others, 1956).
