摘要
冲绳海槽是一个高热流区 ,平均热流值极高 ,但不均匀 ,实测最小值与最大值相差三个数量级以上。结合海槽地区的构造和地球物理特征 ,探讨了导致这一高而分散热流特征的多种因素 ,包括异常壳幔结构、海底热液循环以及地下水对流等 。
Okinawa Trough is a high heat flow region with extremely high but uninformed heat flow value, of which the maximum is three orders larger than the minimum. Based on the specific structure and geophysical features in the region, it is suggested that this special thermal character result from various factors, including abnormal crust-mantle structure, seafloor hydrothermal circulation, and ground water convection as well.and the controlling mechanism of these factors to the heat flow distribution is discussed.in this paper.
