内容記述 | A subcrustal convection current having a linear dimension of a few thousand kilometers accounts for the high heat flows found on the East Pacific Rise provided a velocity of several cm/year and 1℃/km temperature gradient are assumed in the earth's mantle. A long-lived magma of high temperature and a phase transformation layer can give rise to only a fraction of the world average of heat flow for conceivable cases. In general, it is therefore difficult to presume what sort of geophysical events are prevailing in the earth only from the heat flow anomalies observed.|地球マントル内の定常熱対流に伴なう地表同然流量を計算し,通常想像されているように温度勾配を1℃/km,流速を数cm/year程度と仮定すれば,波長1000km程度以上の対流においては,East Pacific Rise海底で観測されるような大きな熱流量の値が期待されることを示した.つぎに地殻内に高温マグマや相転移層が長期間存在する場合の定常熱伝導を調べたが,熱源がきわめて地表に近い場合を除けば,10-6 cal/cm2 sec以上の熱流量を期待することはほとんど不可能であり,このような場合には熱流量の異常を調べて,地下の状態を推定することは困難である. | |||||
