Cap d’or is an area that has been covered by repeatedly by ancient lava flows about 200 million years ago. The basalt, now in layers, was uplifted when the glaciers retreated about 10 thousand years ago. Somewhere in-between the two, there were numerous contacts and faulting. This is also a copper-rich area, making it an interesting combination for rocks.
Here is what I found. Location photos have been previously posted if you are interested in geology, or nature.
Photo 1 - Agate
Photo 2 - Agate
Photo 3 - Agate
Photo 4 – Agate and Jasper Confusion
Photo 5 – Green Moss Agate and Red Jasper Crust
Photo 6 - Blue Agate in Red Jasper
Photo 7 – Survivor Rock
Red jasper was first agatized by blue agate with red plumes. That resulting rock was then fractured and white quartz filled the voids. What looks like fractures have all been filled.
Photo 8 – Agatized Rhyolite
If this isn’t agatized rhyolite, it is green moss agate where the moss dominates the agate.
Photo 9 – 5 Layers
This seam was only about 1” thick, but contained 5 distinct layers. Hope it doesn’t fracture along a layer when worked.
Photo 10 – 4 Layers
Top layer is translucent banded agate when backlit. Second layer is red moss agate. Third layer is brown jasper but has some fine quartz veins. Bottom layer is … ? Well, 3 out of 4 ain’t bad!
Photo 11 – Copper Flakes
This crystalline rock has a copper-coloured crust that has been pulled in a little like moss. Every once in a while the saw would slice through a flake of copper. Not a real beauty, but an interesting one for the specimen collection.
Thanks for viewing.
