General comments

Subject category Comment text
Deposit FIFTEEN SEPARATE SMALL LENSES OF SCHEELITE-BEARING TACTITE. FOUR LENSES PINCHED OUT AT A DEPTH OF 9 M AND THE OTHERS WERE EVEN SHALLOWER. TACTITE BODIES FORMED IN CS GRAINED RECRYSTALLIZED LIMESTONE. IGNEOUS CONTACT TRUNCATES BEDDING AT AN OBTUSE ANGLE, CAUSING ORE BODIES TO BE OF SMALL LATERAL EXTENT. IN THE SOUTHWEST PART OF THE AREA A FEW SMALL STRINGERS OF PEGMATITE CONTAINING SCHEELITE ADJOIN THE ORE BODIES.
