Controls for ore emplacement

  • Nam Pathene Valley Deposits' Principal Ore Is A Surface Enrichment In Lateritic Clay Resulting From Pronounced Weathering Of Tin-Bearing Granitic Rocks And Extending Over An Area Of Some 220 Sq Km.

Comments on the geologic information

  • PRIMARY MINERALIZATION APPEARS TO BE IN VEINS IN PARTLY GREISENIZED MICROGRANITE INTRUDING A BIOTITE- HORNBLENDE GRANITE STOCK AND ITS COUNTRY ROCKS: META-LIMESTONE, HORNFELS AND GARNET-BEARING SKARN. ALSO, TIN MAY BE ASSOCIATED WITH ANDESITIC-RHYOLITIC AND TRACHYTIC-RHYOLITIC SUBVOLCANIC INTRUSIONS EMPLACED DURING TRIASSIC-LOWER JURASSIC EARTH MOVEMENTS. BRECCIATED MYLONITE PROVIDED A HOST ROCK FOR THE TIN MINERALIZATION INTRODUCED BY THE SUBVOLCANIC INTRUSIONS.
