    1:前年度に行なった炭酸カルシウムの沈殿実験の結果,沈殿物の空間分布はランダムに近いことが明らかとなった.しかし一方で,実際に発見されている鉄コンクリーションの空間分布はランダムな分布からずれていると報告がされている.核形成プロセスは確率過程であるので,はじめに形成される沈殿物の空間分布はランダムになることが期待される.このまま沈殿物が成長してゆけば,最終的な空間分布もランダムになる.しかし,沈殿物が成長してゆく過程で隣の沈殿物と合体すれば,沈殿物の大きさに変化が生じることになる.大きな沈殿物と小さな沈殿物がある状態で地下水の状態が変化し,逆に溶解が進行したとすると,小さな沈殿物は消滅して大きな沈殿物が残ることになる.このプロセスにより,当初は空間的にランダムな分布をしていても.その後の成長と溶解プロセスにより空間分布が変化する可能性がある.そこで数値シミュレーションによりこの変化が実際に起こりうるかどうか検討した.はじめに小さな沈殿物を空間的にランダムに配置する.それぞれの沈殿物は一定速度で成長する.成長が進むと沈殿物が合体することもおこる.このようにしてある程度成長させた後,逆に一定速度で沈殿物を溶解させる.小さな沈殿物は消滅し,大きな沈殿物は生き残る.溶解終了後の沈殿物の空間分布を計測したところ,ランダムな分布からは明らかにずれていることが明らかとなった.

    Mechanical properties of dust aggregates strongly affect the first step of planetary formation. If elasticity of an aggregate is large, the collisioncal outcome of aggregates becomes bouncing and growth to planets is prohibited. In this study, elasticity between dust grains was determined as a function of the degree of sintering, which is an efficient mechanism in a protoplanetary nebula. There are four modes of deformation: 1: stretching 2: rolling 3: sliding 4: stretching. The determined elasticity for stretching was smaller than that in previous model. Empirical formulas were derived for the elasticities. The collisional simulation was conducted to check the effect of the modified elasticity. The collisional outcome of numerical simulation was not changed.

    Based on the study, the process of spherical concretions formation was revealed as follows; 1)spherical carbonate concretions are only found in marine sediments. 2)Sphere is formed by the diffusive process. 3)The reason why carbonate has been accumulated, is the process by the reaction with carbon and calcium in the sea water. 4)The fossils inside was well preserved, because of the reason by self sealing. 5)The reaction of carbon and calcium to form concretions is quite rapidly that before we had thought.

    Spherical Fe-oxide concretions in both in Utah and Mongolia have been investigated to understand the geochemical migration features relevant to the heavy metal adsorption. The results are not only Uranium but other REE elements are concentrated in the layer of Fe rich crust. This feature might be used for future heavy metal absorption and fixation technology.
