Thinking about how to present them, I'm stuck between two methods I've seen other bloggers use: show a photo and give a complete explanation of what/when/where/how, or allow readers a shot at figuring out the what & how of the elements in the photo, and filling them in on the rest later on. So as a tryout, I will initially go with my preference, which is the latter. Below are two field photo's I've taken in southern British Columbia:
Field Photo #1 (height of photo =10m)
What do you see here? (hint: two distinct depositional environments are shown) |
Field Photo #2 (GPS = 15cm tall)
What do you see here? (hint: mechanism at work on both rocks) |
Dunno if this format will work or not. Heck, I don't know if I have enough readers yet. But those who do read, feel free to take a stab (or rockhammer) at it in the comments. I'll follow-up later on depending on response, and change method if preferred.
The first one looks like glacial drift but the lower part definately has some cross lamination going on. The 2nd photo is a xenolith but which rocks they are is hard to tell bc the face is so weather-beaten. Could be igneous within igneius, sed rock within igenous, metamorphic within sed rock etcetera
