Geologic Mapping C

[Snayhill]

Do you guys have any idea as to what specific geohazards we should have in our binders?

I'd get the obvious ones, general info about earthquakes, volcanoes, hurricanes, and tsunamis.

Earthquakes, volcanoes, slumps, rockfalls, and rockslides are the ones that immediately come to mind for me. Anything that applied to Dynamic Planet's previous topic would probably fit well.

does anyone have any good geo mapping test?

Unome's geomapping test is on the test exchange

Is there a good geology book that is useful for this event? If there is could someone send me an amazon link to it? Thanks

What do we need to know about geologic maps?

What do we need to know about geologic maps?

How to read them I guess. The rules give the example task of using geologic maps to help assess geohazard risks, construct a cross-section of sub-surface structures, and reconstructing the evolution of a given plate boundary.

The rule says tracing paper and pin. What kind of pin?

The ideal pin would of the capped type sometimes used with nametags. Any type of pin with a flat head should work, provided you can avoid being poked by the tip pointing upwards.

I believe I mentioned an example on the first page: viewtopic.php?f=285&t=12238#p359151 as well as noting that you should find example videos on youtube to see the process (which should help show you why / the type of pin you need): viewtopic.php?f=285&t=12238#p359155. Note for both those cases those are just examples, not necessarily the best or cheapest (aka I was just putting that together quickly as examples, you should look into it yourself of course).

Not sure what Unome means by capped pin for nametags (maybe/probably same thing?), but hopefully that should work/helps. Specify if it doesn't, etc!

On one test, the formula for true thickness was given as T = Wsin(d) + Hcos(d) where T = true thickness, W = width, H = height, d = dip, whereas on another test, the formula for true thickness was given as T = Wsin(d) where T = true thickness, W = width, d = dip. Which one is the correct formula? I am very confused.

What is height?

(Note that a formula for true thickness can be derived using basic trig in emergencies!)

I would strongly recommend deriving the formula yourself, so you understand how it works. There are several standard formulas for true thickness that cover various situations.

Hello Everyone!

I was just wondering if anyone here know what lines that are not faults in a relative dating/strata diagram are. Here's a link https://d2vlcm61l7u1fs.cloudfront.net/media%2Fd3f%2Fd3f1e735-faac-4704-aa99-61fcf269b020%2FphpIiQrsg.png. I'm specifically talking about "G" in this picture.

Thanks!
