Subject category Comment text
Deposit GARNET SKARN LENS IN CALC-SILICATE; LAMPED MINOR TUNGSTEN, MINOR DIOPSIDE, QUARTZ, HEMATITE AFTER PYRITE, CLOTS OF CALCITE, ALL IN PALE GREY HORNFELS NEAR GRANITE. THE SKARN ZONE IS EXPOSED ALONG THE NORTHERN MARGIN OF A GRANITIC STOCK, WHERE THIN-BEDDED LIMESTONES AND QUARTZITES ARE IN CONTACT WITH THE GRANITE. GARNET SKARN LENSES HAVE FORMED IN LARGER MASSES OF CALC-SILICATE ROCK. THE GARNET SKARN IS CUT PERPENDICULAR TO BEDDING BY CLOTS OF CALCITE. THE CALC-SILICATE ROCKS FORM A SHALLOW PENDANT UNDERLAIN BY GRANITE AT A DEPTH OF LESS THAN 100 FT BELOW OUTCROP.
