Shale
1.
Color
a.
Dark gray
2.
Texture (clastic or crystalline/chemical?)
a.
Clastic
3.
Approximate Grain Size (for clastic rocks only: fine, medium, or coarse grained?)
a.
Fine
4.
Sorting (for clastic rocks only: well-sorted, poorly-sorted, or somewhere in between?)
a.
Well-sorted
5.
Depositional Environment (in what general environment was this rock originally formed?)
a.
Underwater where the current is gentle, such as the ocean floor.
Calcareous Tufa
6.
Color
a.
Beige
7.
Texture (clastic or crystalline/chemical?)
a.
Clastic
8.
Approximate Grain Size (for clastic rocks only: fine, medium, or coarse grained?)
a.
Coarse
9.
Sorting (for clastic rocks only: well-sorted, poorly-sorted, or somewhere in between?)
a.
Poorly-Sorted
10. Depositional Environment (in what general environment was this rock originally formed?)
a.
In alkaline conditions, such as salt lakes.
Sandstone
11. Color
a.
Orange around the outside, with a more uniform color where not exposed to the
environment.
12. Texture (clastic or crystalline/chemical?)
a.
Clastic
13. Approximate Grain Size (for clastic rocks only: fine, medium, or coarse grained?)
a.
Fine
14. Sorting (for clastic rocks only: well-sorted, poorly-sorted, or somewhere in between?)
a.
Well-Sorted (but less well sorted than Shale)
15. Depositional Environment (in what general environment was this rock originally
formed?)
a.
In moving water, where there is a current (less gentle than in the formation of
shale but not violent).
Conglomerate
16. Color
a.
Beige with intrusions of various colors (red, gray, and other shades of beige)
17. Texture (clastic or crystalline/chemical?)
a.
Clastic
18. Approximate Grain Size (for clastic rocks only: fine, medium, or coarse grained?)
a.
Coarse
19. Sorting (for clastic rocks only: well-sorted, poorly-sorted, or somewhere in between?)
a.
Poorly-Sorted (less so than Calc-Tufa, if only slightly)
20. Depositional Environment (in what general environment was this rock originally
formed?)
a.
In quickly moving water, such as a river.
Limestone
21. Color
a.
Beige, with mottling of off white where rock that was not exposed to the surface
has been chipped at.
22. Texture (clastic or crystalline/chemical?)
a.
Clastic
23. Approximate Grain Size (for clastic rocks only: fine, medium, or coarse grained?)
a.
Fine-Medium (slightly more coarse than Sandstone and a little rougher to the
touch)
24. Sorting (for clastic rocks only: well-sorted, poorly-sorted, or somewhere in between?)
a.
Medium-Well
25. Depositional Environment (in what general environment was this rock originally
formed?)
a.
In warm shallow water.
Fossiliferous Limestone
26. Color
a.
Beige, with mottling of off white where rock that was not exposed to the surface
has been chipped at. There are intrusions and patterns here where something has
decayed.
27. Texture (clastic or crystalline/chemical?)
a.
Clastic
28. Approximate Grain Size (for clastic rocks only: fine, medium, or coarse grained?)
a.
Fine-Medium (slightly more coarse than Sandstone and a little rougher to the
touch), aside from intrusions.
29. Sorting (for clastic rocks only: well-sorted, poorly-sorted, or somewhere in between?)
