2000, May, Quartz, Calcite

 

While driving on the interstate in Zederhaustal, something caught my attention that I had previously not noticed, a little wall of green-schist. Hidden in the woods, in a small ravine, this formation is visible for but an instant while driving on the motorway. A few days later, I was heading back to this rock-formation. I wanted to climb directly up the ravine in order not to lose sight of my target. Unfortunately, the ascent was more difficult than I had imagined: it was extremely steep and the way up was blocked by numerous fallen trees. Again and again, I was forced to take a detour. Two hours later, quite exhausted, I was standing on the upper part of the ravine. Finally, the wall of green-schist was not that far. When I was standing directly in front of the wall, I saw a little shelf five meters above, and directly above that, I noticed an open, narrow cleft leading into the rock.

I clambered onto this shelf. There, I had just enough room to stand. Now, I looked more closely at the gap. It was about 10 cm wide and 50 cm high. On the left hand side of the rock, in front of the opening, I could see a little crystallized calcite. Above the cleft, a band of quartz extended downwards towards and into the gap. Clearly very promising signs for an interesting cleft! I reached into the opening, felt smooth surfaces, and pulled out a perfect quartz crystal of about 10 cm length.

This was my first beautiful quartz crystal from a cleft of green-shist. To get deeper into the cleft, I started working feverishly. I broadened the opening with my chisel, but the cleft soon ended.  I managed to salvage four single quartz crystals worth collecting and one matrix-specimen. Two of the quartz crystals are translucent and partly colored green by chlorite. One double terminated floater piece is chloritized completely and highly lustrous black. Small magnetites are also crystallized on the matrix specimen.
