ESC2000 Lecture Notes - Lecture 2: Sulfur, Inta, Calcite
Document Summary
Naturally occurring inorganic solid with a definite & distinct internal atomic structure & chemical composition. 4000 minerals of which contain the 2nd most common elements in the earth"s crust. Feldspars (s1o2) most common minerals fe, al, ca, na, k, mg // (s1o2) 2nd most common. Element substance that can"t be broken down into a simpler substance. Elements are made of atoms smallest particle that exists as an element. Most minerals are made up of two or more elements. Compound substance with two or more elements that are chemically combined. But there are many single element minerals: gold, silver, copper, sulfur, diamond. Protons (+) the number of protons in nucleus that defines the elements. Crystal external expression of a minerals internal atomic structure: precipitation. The slower the magma cools, the larger the crystal will become. Cave limestone: metamorphism application of high heat &/or pressure to an existing body of rock. Luster ex: metallic, glassy, pearly, earthy how a mineral looks .
