Ogliuga Posted January 20, 2022 Share Posted January 20, 2022 There is a large area with red soil here in Tuscany, central Italy. Area where we have an intense mineralization, red dirt. Years ago I took this stone which I use to make some quick test at home. Hematite is an iron ore and that’s why I need pulse inductions too.. 1 Link to comment Share on other sites More sharing options...
JCR Posted January 20, 2022 Share Posted January 20, 2022 We have hematite here in our East Texas area also along with maghemite & limonite iron ores. My red dirt sites will cover a magnet with little bits, pebbles & fuzz. Quite a few of the darker rocks are hot. It is a special needs type of dirt for sure. I don't have a PI unit but my Tarsacci MDT 8000 handles it well. 1 Link to comment Share on other sites More sharing options...
Ogliuga Posted January 20, 2022 Author Share Posted January 20, 2022 Thanks for your reply! I’ve never tried with a magnet but it is a test I have to do. There’s bauxite as well. When I touch the soil with the pinpointer before doing ground balance, it screams.. Anyway think Tarsacci is a really serious machine! 1 Link to comment Share on other sites More sharing options...
JCR Posted January 20, 2022 Share Posted January 20, 2022 I would think bauxite would be problematic depending on the concentration. Link to comment Share on other sites More sharing options...
