Presentation Transcript

  1. Regarding geological survey Geological fieldworks observations and tectonic measurements are strenghtened by - 120 ages by zircon mineral analysis • 15 ages by K/Ar method • 500 whole rocks chemical analysis • 1,300 whole rocks analysis for multi – elements assay • 2,500 new thin sections added to thin sections generated by former programs also studied • 500 mineral microprobe analysis • 28.000 stream sediments and panned heavy minerals

  2. The legend of the renewed geological map is better shaped than former

  3. Sample of renewed geological map at 1:500,000 scale

  4. Sample of renewed structural geology map at 1:100,000

  5. Sample of new geochemical Map at 1:200,000 scale

  6. Legend of geochemical Map for Mn element

  7. Are also available • Hydrogeology • Geomorphology, • Metamorphism • Distribution of ages Other thematic maps on Satellite imageries • JERS radar images • ASTER images

  8. Map of the Tectono-Metamorphic Domains of Madagascar (PGRM, 2008)
