Dimitris posted a topic in General Fossil DiscussionHello all! I am trying to find some new areas around my place. So far there is not a single reference for fossils in this place, so I need somehow to choose some spots to prospect. There are some common rules like road cuttings, rivers & creeks that cut into the formations, abandoned quarries etc, all of which are beautifully presented in this post. However, I need to know how to take advantage of all information provided in a geological map. Which place would you check first for fossils? There are faults, borders between two geological ages etc. What are those numbers next to this symbol that looks like T (sometimes inversed)? *As per the legend this T represents foliated and stratified rocks. Additionally, on the legend there is description of the rock composition of each formation. Which of those would you consider to check first? Sandstones, clay, sandstone clay, marl. I guess these must be my best candidates while volcanic and metamorphic deposits like amphibolite and tuff should be excluded. Using Photoshop, I managed to create a picture that combines the geological map onto the actual map. First I need to have both maps at the same scale, then I create two layers in Photoshop. My main layer is the geologic map and the actual map is placed upon the other. Using the opacity, I can change the transparency of the layer and like this I am able to pin point the exact location of interest. Here is the place of interest Looking forward to hearing your comments and ideas on prospecting. Happy hunting
For Christmas I was given a Garmin GPSMAP 64 device. I would like to load geologic maps on the device to help with my field work, but I can’t figure out how to convert files so they can be loaded. Does anybody know how to convert standard Geologic information files like mpk files to the format needed for Garmin devices? I can’t spend a lot of money on GIS software. Thanks!!
