Geology Exploring Earth-Week 3 Notes Here's Thursdays notes including a concept map for minerals. Tuesday was the snow day. MINERALS CONCEPT MAPPING EX: SPECIFIC CHARACTERISTICS: PYRIT MINERAL - SOLID -NATURAL METAL E -INORGANIC S &SULF NATIVE -ORDERED INTERNAL SULFID METAL HALOGE S STRUCTURE NS HALIDE ES NaCl S CLASSE SILICATES-ALL -SPECIFIC CHEMICAL (SALT) OXID S HAVE SILICA MOST -ORDERED INTERNAL CARBONAT COMMON STRUCTURE ES S TETRAHEDRO METAL EX: N -SPECIFIC CHEMICAL &OXYG CALCITE EN CO3 COMPOSITION EX: HEMATITE THESE ARE IMPORTANT BECAUSE THEY GIVE THE (FeSO3) MINERAL CLASSES ARE BASED MINERALS PROPERTIES THAT ON A SPECIFIC CHEMICAL WE USE TO DISTINGUISH COMPOSITION. THEM: SUCH AS... -STREAK -COLOR -LUSTER -HARDNESS -CRYSTAL FORM -CLEAVAGE -DENSITY MINERALS MAKE P ROCKS AND ARE USED TO MAKE COMMODITIES WE USE DAILY. THEY ARE THE BUILDING BLOCKS FOR ROCKS WITH DEFINED PROPERTIES LISTED ABOVE IN THE BOTTOM LEFT TEXT BOX.
