Re: Re: Re: Oregon Rock ID help From Cristmas Valley

The best and cheapest way that I know of to obtain a chemical analysis is to provide samples to a local colledge chemistry/geology department. If I providethem with sufficient intersting material that is relavent to ongoing studies they will sometimes to it for nothing. There are several scientific labs around the country that will perform testing but it get expensive quickly. try "googling" chemical or mineral analysis". I would venture to say it does not appear like you have a valuable mineral there so I would probasbly continue to dig and enjoy them and perhaps send some to a local club for another hands and eyes on opinion.
