One is the rising resulted from the buoyancy of acid plutons, e.g. granite and migmatite which are lighter in density, being 2.67 and 2.76 respectively. The other is the rising due to the squeezing of mafic and ultramafic plutons, e.g. peridotite and gabbro which have heavier densities of 3.23 and 2.98 respectively.\\nThere has been no verification for the mechanism of squeezing so far, though the mechanism by buoyancy has already been proposed by such authors as RAMBERG (Gravity, Deformation and the Earth's Crust, Academic Press, 214p, 1967) and KIZAKI (J. Fac. Sci. Hokkaido Univ., Ser. 4, 15, 157, 1972) and others.\\nThe term squeezing signifies that when a pluton is heavier than its surrounding rocks (crust), the pluton is squeezed out by the pressure of the surrounding rocks. The rising of pluton by squeezing is demonstrated numerically by a computer simulation in the present paper.","subitem_description_type":"Other"},{"subitem_description":"深成岩の上昇に関して，それらの成因上2つの機構が考えられる．1つは酸性岩，すなわち密度2.67g/cm^3の花崗岩や2.76g/cm^3のミグマタイトなどの，浮力による上昇であり，他は，超塩基性ないし塩基性岩，すなわち密度3.23g/cm^3のカンラン岩や2.98g/cm^3のハンレイ岩などの，しぼり出しによる上昇である．浮力による上昇機構はRAMBERG（Gravity,Deformation and the Earth's Crust, Academic Press, 214p, 1967)やKIZAKI(J.
