Comments on the workings information

  • THE WORKINGS CONSIST OF SHALLOW TRENCHES AND OPEN PITS TRENDING NW. FOR 1/4 MI. ONE TRENCH MEASURED APPROXIMATELY 76.2 M (250 FT) LONG, TRENDING N14E. APPARENTLY THIS IS THE TRENCH EDMUNDSON (1938) DESCRIBED AS BEING 3 TO 6.1 M (10 TO 20 FT) WIDE AND A MAXIMUM DEPTH OF 3.7 M (12 FT); ONLY THE OUTLINE OF THE TRENCH WAS VISIBLE IN 1975. THE PITS MEASURED UP TO 3 M (10 FT) IN DIAMETER AND UP TO 1.8 M (6 FT) DEEP, WHEN SEEN IN 1975.

Comments on development

  • DUE TO ITS LONG PERIOD OF INACTIVITY AND POOR SHOWING OF BARITE, THIS PROPERTY HAS BEEN CONSIDERED BY SOME RESIDENTS AS AN OLD METAL MINE. MINE CONSISTED OF PITS AND TRENCHES. IT WAS OPENED A SHORT TIME AFTER THE CIVIL WAR AND PRODUCED ABOUT 2,200 TONS OF BARITE.

Subject category Comment text
Deposit THE ABOVE FIGURES APPLY TO THE LARGEST CONTINUOUS WORKINGS. NO BARITE WAS FOUND ON THE SURFACE OR IN THE WORKINGS IN 1975. THE MINE OCCURS IN THE DECOMPOSED PART OF A DIABASE DIKE, THE ONLY KNOWN OCCURRENCE OF THIS TYPE IN VIRGINIA. THE BARITE IS ASSUMED TO REPRESENT ORIGINAL FISSURE FILLINGS OR REPLACEMENT OF THE DIABASE.
Deposit ALL OF THE WORKINGS ARE IN THE DECOMPOSED PART OF THE DIABASE DIKE WHICH CAN BE TRACED ACROSS THE BARITE AREA EAST OF THE SOUTHERN RAILWAY. THIS OCCURRENCE OF BARITE IN DIABASE APPEARS TO BE UNIQUE FOR VIRGINIA. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV; 5 PERS COMM
