Comments on the geologic information

  • THE HOST ROCK CONTAINS MICROCLINE, PLAGIOCLASE, TOURMALINE, AND ZIRCON AND HAS AN AVERAGE TIN CONTENT OF 0.0005%. RED BLUFF GRANITE WAS RECOGNIZED TO BE ONE OF THE YOUNGEST PRECAMBRIAN INTRUSIONS IN THE FRANKLIN MOUNTAINS. IT IS LATE PROTEROZOIC, APPROXIMATELY 950 M.Y. OLD. ROMARCHITE (SNO) WAS REPORTED IN MICROCLINE PEGMATITE, BUT THE DATA DO NOT SUPPORT A DEFINITE IDENTIFICATION. THE BUREAU OF ECONOMIC GEOLOGY'S X-RAY DIFFRACTION OF HEAVY-MINERAL SEPARATES OF SAMPLES FROM THE SAME LOCALITY INDICATES THE PRESENCE OF CASSITERITE, FLUORITE, PYRITE, AND TOPAZ, BUT NO ROMARCHITE.
