These are a few more of my weekend finds from McKay Head. In general, vugs in amygdaloidal basalt have been lined with a rind of blue chalcedony, then filled with opaque quartz crystals. The quartz crystals tend to form in outward radiating spheres, that locals call “quartz flowers”. In some instances, the opaque quartz crystals have been coated with thin laminations of geyser opal.
The find-of-the-day was this thin shelled broken nodule. At first glance, it was somewhat interesting as a nodule. But after a closer look and cleaning, the inside was lined with tiny quartz spheres. I tried to photograph the inside, but am having problems with depth of field, so the focus isn’t crisp everywhere.
The next two are pieces of thin shelled geodes where the thickness of the rind in only a few millimeters. Really fragile.
The next three are loose quartz flowers that have fractured out of geodes.
The last few are partial geodes still attached to the basalt matrix.
