| PYRITE SUN from a Coal mine in Sparta, Illinois | ||
 |
#R-543 LARGE, 3.5" diameter | $24.00 |
| Did you know? That Black Jet, made popular in turquoise jewelry, is actually a type of fossilized COAL formed 180 million years ago from dead trees? TRUE. | ||
DESERT ROSESFrom Naica, Chihuahua, Mexico. Found in a mine cavern are these glassy gypsum formations called "selenite". Crystals grow as opaque sand-filled crystal clusters with mica-like sheets. Clusters can be HUGE (room-sized) or just single ball rosettes. Under shortwave UV light, they fluoresce a bright cream color and are moderately phosphorescent, a good customer named Mike reports. Thanks, Mike! Gotta have one? |

SEPTARIAN NODULE specimensSeptarian nodules are found 15 miles E of Zion National Park, Utah. They were formed in an ancient sea floor during the Cretaceous period, 50-70 million years ago when the Gulf of Mexico extended into Utah. On the ocean floor, mud formed around decomposed sea life. Rocking back and forth in the water caused mud balls. When the ocean receded, the mud balls dried and cracked open. Over the eons to follow, mineralized solutions deposited in the cracks. First forming brown ARAGONITE, then golden CALCITE and occasionally BARITE clusters were formed within the cavities. The outside of the mud ball is now a gray limestone rock. As the nodules weathered out of the gray clay hills, at one time they could be picked up by hand on the surface. Now, excavating equipment is required for extraction, 20-40 feet underground. The name "Septarian" is Latin "Septem" meaning seven. The mud balls cracked with seven points in every direction, creating a beautiful design. The fossil which started forming the Septarian nodule is sometimes noticeable in the rock. So, yellow center = Calcite, Brown lines = Aragonite, Gray rock = Limestone. One side polished to a high sheen; these work well as coasters for the coffee table, or lovely display pieces Priced as marked; these are 1/2" thick slabs |

| MIMETOLITHS
Cool Customer Kristal shared photos with us of his great collection of mimetoliths (a natural topographic feature, rock outcrop, rock specimen, mineral specimen, or loose stone the shape of which resembles something else). Let your curiosity take you to searching the net using the word "mimetolith", you will find some amazing formations, it can be addictive. here's one example: http://www.cst.cmich.edu/users/dietr1rv/mimetoliths/ My most recent experience would be in the Kartchner Caves in Arizona, where there were bacon, eggs and angel formations within the cave which were mind boggling (see Latest Travels, for November 2007 for photos). Our neighbor Rebecca came across this tree stump that beavers had gnawed into what looks like an elephant head. See what you think:
