The Lime Crest and Franklin (or "Farber") quarries of Sussex County were host to a surprisingly large number of mineral species.


Those tiny black specks near the center of the photo are collectors. 
This area later became flooded with water;  more recently it may have been drained.

The minerals of Lime Crest are mostly underwater now.  The "official line" has it that the quarry was bought out deliberately by a multinational with the goal of shutting it down (to eliminate competition, I guess).  I find that a bit hard to believe, because it can't be cheaper to import bulk stone than it is to quarry it locally.  Fuel costs may be lower, but that's never reliable.  There is a whole back-story involving a couple of people who wanted to get the quarry shut down because of the dust, noise, etc.  This certainly played a role in the quarry's demise.

There are numerous minerals that occur in the impure marbles of Franklin, Ogdensburg, Sparta, Hamburg, McAfee, etc... there are still minerals I haven't added to the list.  Lime Crest was by far the biggest and best marble quarry in the region, but sadly it's gone (or not?... see below.)   The good news is that the uppermost levels (which sit essentially even with the landscape) still have quite a bit of mineralized rock.   While the quarry was flooded, there were still collecting trips to the dry upper levels.  I wish I'd gone on some of these. 

Here's an enouraging update:  According to Mindat, the quarry was apparently drained in 2013 and is operating again.   As for the collecting status, I do not know. 


Finally, there are still other windows into the Franklin marble;  if we include the Amity-Warwick area of New York, there are even more sites yet.  All of them have similar mineralization, though certain minerals (e.g., warwickite) appear to be more localized.   Also-- just my informal observation here-- Lime Crest seemed to have mineralization that didn't appear so much in the ones farther away from the Franklin-Sterling Hill complex.

What follows is a listing of some minerals that occur in these quarries.  I'veI divided the list in two, just because I didn't want pages that seemed to scroll on forever.
