Document Summary
Dolostone:a sedimentary carbonate rock composed primarily of the mineral dolomite. Dolostone at rock chapel was formed through a process called dolomization. This process involving the replacement of some of the calcium in limestone with magnesium to create dolostone. This leads to the reduction in volume and vugs are left behind. Sandstone: a clastic sedimentary rock composed of sand sized grains. Limestone: is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate. Can be characterized by its fissile nature and thin bedding. Seismic waves - energy released during earthquakes, pulverizes rocks generates heat and causes vibrations. Primary (p) - travel through solid and liquid, faster then s. Secondary waves (s) - don"t travel through liquid at all but do travel through solids. Surface waves - travel through surface of the earth, are the most damaging because of high amplitude and how they move.
