【摘要】 本文根据C.A.Swanberg和P.Morgan提出的利用地下水中二氧化硅达到平衡状态时的温度与实测的大地热流值之间的经验公式,计算了南北地震带北段的硅热流值,并作出了硅热流值等值线图。研究结果显示了该地区的硅热流值整体上属于中等正常值,其高值区属于弱正异常。本文还讨论了硅热流值与地质构造的关系。更多还原

【Abstract】 Based on C. A. Swanberg and P. Morgan’s. empirical formula between temperature of silica equilibrium state in groundwater and practical earth heat flow data, this paper calculates the silica heat flow values in the northern segment of North-South Seismic Belt, and gives the outline of siliea heat flow isogram of this region. The result shows that the silica heat flow as whole is middle normal value, and the high silica heat flow region is feeble anomaly. In addition, the relation between silica heat flow and tectonics is also discussed.更多还原
