Nebraska, USA

Dimensions: 14.2 cm x 6.2 cm x 5.5 cm
Weight: 671 g

Large alluvial cobble of “Prairie Agate” (two sides), most likely from the Ogallala National Grasslands in northwest Nebraska, in the same general area that Fairburn Agates (or “Fortification Agates”) are found (and also in the Black Hills in South Dakota). Some are also found occasionally in the Platte River alluvium all the way to the eastern part of the state.

Prairie Agate was designated the “state rock” of Nebraska in 1967. That fact is a hint that it is not really agate (a mineral), but chert (a rock). It is very hard and takes a good polish, but the layers are generally not as distinct as banded agates usually are.

Prairie Agate is believed to have originated in mostly marine sedimentary limestones of Middle to Late Pennsylvanian and early Permian ages that were deposited in the Front Range and Hartville Uplift of Wyoming and in the Black Hills of South Dakota. These rocks were subsequently eroded and the hard siliceous materials were carried into Wyoming, South Dakota, and Nebraska by streams that deposited basal conglomerates in the Chadron Formation of Oligocene age. (Source: Nebr. Geol. Survey “Agate Lexicon”).

RT9-21RClinoptilolite, Quartz SiO2 , Calcite CaCO3

Kanan Road Quarry, Agoura Hills, Santa Monica Mts, Los Angeles Co., California, USA

Dimensions: 58 mm x 47 mm x 37 mm

Clinoptilolite with quartz and calcite, on basalt, from the Kanan Road Quarry, about 30 miles west of downtown Los Angeles. The clinoptilolite occurs as brilliant small (sub-mm.) glassy crystals intergrown with tiny quartz crystals. Much larger crystals and masses of cream-colored calcite cover much of the surface. Ex Robert Ray (Northridge, California), with an acquisition date of 1971, then went to Dave Shannon, and later, Dana Slaughter.

QX8-2RTFerberite FeWO4

Multiple photos available
Old Mine Park, Long Hill, Trumbull, Fairfield County, Connecticut, USA

Dimensions: 20 mm x 13 mm x 11 mm
Weight: 11.3 g

Ferberite pseudomorph after a bipyramidal scheelite crystal. Opposite side (child photo) shows attached blady yellow crystals which I believe to be tungstite (but not analyzed). Ex David Burgess (6/17/1983), via Alan Benson. I measured a specific gravity of 6.3 for this specimen.

W5T-E53Hematite Fe2O3 , Goethite α-Fe3+O(OH) , Glauconite (K,Na)(Fe3+,Al,Mg)2(Si,Al)4O10(OH)2

Cass Co., Texas, USA

Field of View: 20 cm

Typical nodules of bog iron ore from Cass County, Plate 7 of Eckels (1928) The Brown Iron Ores of East Texas, USGS Bulletin 902. Bog iron ore was mined extensively in East Texas, beginning in Civil War times. The nodules are primarily limonite and hematite replacing glauconite. Some higher-grade nodules contain shiny, botryoidal goethite in the center.
