Identity HelpYellow mineral help on calcite from NJ

6th Nov 2019 03:37 UTCBrian Fussell

This calcite specimen is from either Franklin or Sterling hill and has some franklinite crystals and small amount of willemite, but I dont know what these yellow minerals are, they do not fluoresce. So not being all that familiar with this NJ material I was hoping someone here might have an idea what they could be.

Andradite grains and masses of different sizes, very common at both Franklin and Sterling mines.

Agree with Steven....very, very common at Franklin and Sterling mines.

Now that I have taken a closer look some of my other similar specimens I see what you mean as being very common, I was thinking sphalerite like Kevin suggested on these previously.
