Dating rocks and soils


Basaltic rock that cools slowly in a large thick layer will often form a distinctive hexagonal prismatic columnar jointing that produces "columnar basalt". These isotopes decay within the rocks according to their half-life rates, and by selecting the appropriate minerals those that contain potassium, for instance and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined. These ancient rocks have been dated by a number of radiometric dating methods and the consistency of the results give scientists confidence that the ages are correct to within a few percent. For example, feldspar crystals in a volcanic tuff commonly weather to form new clay minerals. Inhibition Model of Succession This model of succession suggests that the change in plant species dominance over time is caused by death and small scale disturbances and variations is plant species longevity and ability to disperse. As the plates spread, more basalt attaches to the plate. In the spring, these cracks fill with liquid water from melting snow which subsequently re-freezes. Ideal Gas Law This law describes the physical relationships that exist between pressure, temperature, volume, and density for gases. For example, a rock fragment carried along in a river's current continuously bounces against other fragments and the river bottom and eventually is broken into smaller pieces. Thus the graphic illustration of the geologic time scale, showing both relative time and radiometric time, represents only the present state of knowledge. A basalt, on the other hand, which has a high percentage of ferromagnesian minerals, weathers to a darker-colored soil that is higher in clay content and lower in quartz.
