Succession of flora and fauna refers to the deposition of sedimentary material, which will include the remains of plant and animal life that existed at the time of the deposition of these rock particles. The fossils of these plants and animals will be found in the rock formations that result from the deposition. The presence, absence, or change of the plant and animal life within a sequence of the geologic column provide important information that allows for the correlation of rock formations (and, thereby, relative time) from location to location. Also, the fossil records within sequences give important information regarding the evolution of life through geologic time. 

This system for keeping track of these important units is used as the basis for the standard geologic lime and the evolution of the animal life on earth. (See also Tables 2-26 and 2-27.) Table 2-28 gives the relationship between geologic time and important physical and evolutionary events that are used to aid in the identification of rock units in relative geologic time [26]. 

On a larger scale, landscape development reflects those mechanisms that expose bedrock, weather it, and transport the weathering products away. Present and past tectonism, geology, climate, soils, and vegetation are all important to landscape evolution. These factors often operate in tandem to produce characteristic landforms that presumably integrate the effects of both episodic and continuous processes over considerable periods of time. 

Numerous studies on the geologic and tectonic evolution in and around the Japanese Islands from Miocene to present have been carried out (e.g., Kitamura, 1959 ... 

However, in contrast to these geologic and tectonic studies, very few studies on the relationship between tectonics and hydrothermal system in Neogene age have been carried out. Therefore, these studies are briefly summarized and then the relationship between geologic and tectonic evolution and evolution of hydrothermal system associated with the mineralizations (Kuroko deposits, epithermal veins) are considered below. 

The causes for the different site of hydrothermal activity (submarine and subaerial environment) could be considered in terms of tectonic and geologic evolution of this metallogenic province from middle Miocene to Pleistocene.

The geological sciences are involved in studying the naturally occurring materials of the earth and solar system (i) to understand the fimdamental processes of crustal formation on earth and solar system evolution, and (2) to evaluate the crustal materials of potential economic value to man. Prior to the 1930 s, analyses were carried out exclusively using classical analytical techniques, with detection limits on the order of o.oi-o.i % (mass fraction). The number of elements contained in any sample could be as extensive as the periodic table, but very few of these could be determined. The development of instrumental techniques revolutionized the analysis of geochemical samples, beginning in the 1930 s.
