I found this Quartz Crystal Cluster on top of the forest floor yesterday while hiking in the Ouachita National Forest here in Arkansas yesterday. Most of it was covered in leaves, but I saw one side with some of the clear crystals showing. This Quartz Crystal Cluster was heavy and I was about six miles from my cabin so I left it in the forest near where I found it. It would make a great show piece and I may retrieve it if I hike this area again.
I have written about the Quartz Crystals here in Arkansas before: Arkansas Quartz Crystals
In 1967, the General Assembly adopted the quartz crystal as the Arkansas State Mineral.
Quartz is the second most abundant mineral in Earth’s continental crust.
There are many different varieties of quartz, several of which are semi-precious gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings.
The ideal crystal shape is a six-sided prism terminating with six-sided pyramids at each end. In nature quartz crystals are often twinned, distorted, or so intergrown with adjacent crystals of quartz or other minerals as to only show part of this shape, or to lack obvious crystal faces altogether and appear massive. Well-formed crystals typically form in a ‘bed’ that has unconstrained growth into a void; usually the crystals are attached at the other end to a matrix and only one termination pyramid is present. However, doubly terminated crystals do occur where they develop freely without attachment, for instance within gypsum.
Quartz is a defining constituent of granite and other felsic igneous rocks. It is very common in sedimentary rocks such as sandstone and shale and is also present in variable amounts as an accessory mineral in most carbonate rocks. (Wikipedia)
