OUTCROP AND HAND SAMPLE PHOTOS AND VIDEOS
There are at least two conglomerate beds in this outcrop. These images show the conglomerate with the larger (cm-sized) clast size.
The videos below show both the larger and smaller clast sizes.
Thin Section Photos and Videos
1st = plane polarized light; 2nd = cross-polarized light.
The thin section images are from the smaller clast size conglomerate. This close-up shows clasts of quartzite (top), k-feldspar/granite (bottom right), and shale (bottom left). There are also volcanic clasts in these rocks. The volcanics are from the Mount Rogers complex – remember this from the history of magmatism in VA?
Entire thin section scan. 1st = ppl; 2nd = xpl.
The shale clast is on the left – it’s the darker clast. Other rounded clasts can be seen in ppl and xpl.
