Old quarries, road cuts, and exposed landscapes are being examined by new generations of minerals enthusiasts. Each needs a comprehensive guidebook with clear photographs and accurate data. This is it. \u003c\/p\u003e\u003cp\u003e In a thick but handy format, more than 700 different minerals and rocks are grouped by color (for ease of location in the book) -- blue, red, yellow, brown, green, white and black crystals; brown and gray sedimentary rocks; and meteorites for anyone lucky enough to find one. \u003c\/p\u003e\u003cp\u003e Each has a picture -- four to a page -- opposite detailed but clear data: \u003c\/p\u003e \u003cul\u003e \u003cli\u003e Chemical formula \u003c\/li\u003e \u003cli\u003e Hardness \u003c\/li\u003e \u003cli\u003e Color \u003c\/li\u003e \u003cli\u003e Density \u003c\/li\u003e \u003cli\u003e Lustre \u003c\/li\u003e \u003cli\u003e Cleavage \u003c\/li\u003e \u003cli\u003e Fracture \u003c\/li\u003e \u003cli\u003e Tenacity \u003c\/li\u003e \u003cli\u003e Crystal form \u003c\/li\u003e \u003cli\u003e Similar minerals and where they are likely to occur.
