[QUOTE="kurra, post: 342514, member: 9971"] Hi, not sure if this is the right spot for this question and please move it if you feel it is under the wrong topic. The area I have been detecting in is known to contain gold, silver, arsenic...... and so on. My question is, I know they come in crystal form, but can arsenic, orpiment (arsenic sulfur) come in a powdered form throughout the rock, possibly after oxidization? I have found some rocks that seem to have a very vibrant scarlet type red and yellow through them and was concerned. I wouldn't know what to look for, for my own safety. They probably only contain Iron and yellow clay and I guess it is better to er on the side of caution and wear gloves. Does anyone have any photo's of rocks we should be wary of. I have looked it up on a google search and there are a couple of rocks that look similar to the ones I have, but most are in crystal form. Also, what is the difference between pyrite and asenopyrite? Do we have a topic or a group of photo's that show rocks to avoid? Sorry for all the questions, but I have no idea what to look for. I was also wondering whether most gold deposit come with mos/somet of these dangerous minerals? thanks,K [/QUOTE]
