Primary Minerals,tered in moist climates. The composition of primary minerals in soils is affected by the types of parent rocks, weathering, sorting, and other soil-forming factors, resulting in mineral compositions that deviate from the average mineral composition of the Earth’s crust.

Secondary Minerals,l, and biological functions of soils. As the size of secondary minerals is approximately 2 μm or less, electron micrographs and X-ray diffraction (XRD) are effective for characterizing these minerals. Schematic diagrams are used to interpret the chemical structure of phyllosilicate clay minerals.

Non-crystalline Inorganic Constituents of Soil,phane and imogolite are rich in Al whereas their parent material, volcanic ash, is silica-rich. Changes in morphological property and element concentration of volcanic ash or volcanic glass during the formation of these secondary non-crystalline constituents are discussed.

Introduction,ogeneous dynamics, we mean two different kinds of dynamics: Time-driven continuous-variable dynamics, the evolutions of which are typically governed by physical laws and are described by differential or difference equations; and event-driven discrete-variable dynamics, the evolution of which depends
