Aegirine showing color zoning from 3M Big Rock Quarry, Pulaski County, Arkansas. This is from a quartz xenolith collected in the 1980's. The aegirine formed from these xenoliths is extremely zoned. I ran EPMA on one of these and the composition is essentially identical for all the zones. Apparently the colors reflect the oxidation states of the Fe and not a change in %. Imaged with a Canon 40D, 30mm B&L lens and stacked with Combine Z. FOV about 1.5 X 2mm
Pink tabular brithiolite with golden eggletonite, zoned aegirine and yellow zircon on analcite and feldspar., 3M Big Rock Quarry, Pulaski County, Arkansas. This specimen is from a thin vein that contained the first eggletonite that Mike Howard and I recognized from the quarry. The Smithsonian had sent us a tiny fragment from the type specimen to look at and very shortly we found several small pegmatites that contained the mineral. Small amounts have turned up two more times since then, but it is not a common mineral in the quarry. Imaged with a Canon 40D, 23mm Nikon objective mounted on a 300m

Tiny yellow ball of gaidonnayite on feldspar and aegirine from the 3M Big Rock Quarry, Pulaski County, Arkansas. The late Art Smith first showed me these and asked if they were zircons because of the high refractive index. I ran powder XRD on some and found that they were gaidonnayite. The gas cavities frequently contain examples, but their tiny size also causes them to be overlooked. FOV is about .5 X .4mm.

Weird looking allanite from the eggletonite pegmatite we found at the 3M quarry. The allanite from this vein ranges from this brown to an almost red. It needs analysis like all the allanites.

This is what appears to be a new mineral species from the 3M Big Rock quarry, Pulaski County, Arkansas. Associated minerals are analcime, aegirine and brown needles of eggletonite. This is the only group of free growing crystals I've located so far. All the other specimens span the vugs, or are embedded in the syenite. These have only been found (so far) in the eggletonite pegmatite collected this spring and in the brown syenite pegmatite we collected about a decade ago. There appears to be no reason it is not present at Granite Mountain Number 1. Problem right now is that we have previously

Here is an old specimen from the 3M Quarry, Pulaski County, Arkansas. Golden blade of kuptletskite with typical "feather" termination , secondary aegirine "puffballs" and a nice Niobian titanite. The LED ringlight shows the green color of the Nb-titanite nicely.  When you use incandescent light, the titanite has a distinct red color. If you try and image one, it comes out  a disgusting greenish-brown color! FOV is about 1 X .7mm. Imaged with a Canon 40D, 23mm Nikon objective and 300mm Canon FD telephoto in a tube configuration.

Yellow tetrahedron of helvite with pink bastnaesite and white manganoan calcite from the Granite Mountain Number 3 Quarry, Saline County, Arkansas. This amazing quarry is difficult to collect anything from. It is small and normally dusty!

Imaged with a Canon 40D, 30mm B&L lens and stacked with Combine Z. FOV about 1.5 X 2mm
Bastnaesite from the 3M Big Rock Quarry, Pulaski County, Arkansas. This specimen has 8 of these tabular bastnaesite crystals on it. I collected the fragment from the central dike rock border pegmatite in 1986. It just popped out as I was breaking rock. I never found another fragment in that particular material! Imaged with a Canon 40D, 30mm B&L lens and stacked with Combine Z. FOV about 1.5 X 2mm
Bastnaesite ? with aegirine, feldspar and an unidentified green micaceous mineral from Granite Mountain Number 3 Quarry, Saline County, Arkansas. I call this one "Adam
Bastnaesite ? with aegirine, feldspar and an unidentified green micaceous mineral from Granite Mountain Number 3 Quarry, Saline County, Arkansas. I call this one "Adam's ant" (after my son who helped me collect it) because the group of bastnaesite hemispheres looks like an ant staring down at a patch of grass from an aegirine "twig". Imaged with a Canon 40D, 30mm B&L lens and stacked with Combine Z. FOV about 2 X 2mm
Eudialite embedded in pectolite from a cavity found at the Diamond Jo Quarry, Magnet Cove, Arkansas. One boulder produced a fairly large number of euhedral eudialite crystals, some free growing, but the majority embedded in fibrous pectolite like this example. The "gas" cavities are actually fluid bubbles cooked off of xenoliths sinking into the syenite magma.  They are confined to the pseudoleucite syenite bordering the Magnet Cove complex. Assimilated xenoliths comprise the remaining cavities in these syenites.

Yellow titanite on aegirine from a quartz rich xenolith, 3M Big Rock Quarry, Pulaski County, Arkansas. Imaged with a Canon 40D, 23mm Nikon objective mounted on a 300mm Canon FD lens in a tube configuration. Stacked with Combine Z. FOV is about .4 X .5 mm

Not a real attractive shot, but my best specimens of this are gone. Pink brithiolite with zircon and eggletonite from 3M Big Rock Quarry, Pulaski County, Arkansas. This was collected about 1987 from thin pegmatite dikes in the west end of the quarry. Unfortunately little activity has taken place in that area since. Most the brithiolite located has been white fibers, but this material is very interesting tabular hexagonal plates. FOV is about .5 X .4mm. Imaged with a Canon 40D, 23mm Nikon objective and 300mm Canon FD telephoto in a tube configuration and stacked using Combine Z software.
