本文叙述了西太平洋、澳大利亚和东亚的热流分布及其地质解释。从东亚和西澳大利亚区的469个观测值中确定平均热流值为63mW/m~2;在白令海一新西兰区的1215个测定值中,均值为80mW/m~2, 同亚一澳(包括中澳和东澳)太平洋过渡带的热流值基本一致;西太平洋472个测站的平均热流值为53m/Wm~2。这些资料揭示:1)亚一澳以东的白令海—新西兰区的热流值随着地幔上顶面埋深的减小而同步升高; 2)热流值不取决于岛弧的年龄;3)热流值主要依赖于地质构造年龄的结论不能成立,但可断定它与最近的构造活动有着直接的联系;4)岩浆源(局部熔融带)是热流最大值的来源,岩浆源上顶深度为15—30千米。
This article describes the distribution of heat fluxes in the Western Pacific, Australia and East Asia and their geological interpretation. From the 469 observations in East Asia and Western Australia, the average heat flow was 63 mW / m 2; in 1215 measured values in the Bering Sea-New Zealand region, the mean was 80 mW / m 2, Australia and East Australia) Pacific transitional heat flow values are basically the same; the average thermal flow value of the 472 stations in the western Pacific is 53m / Wm ~ 2. These data reveal: 1) the value of heat flow in the Bering Sea-New Zealand zone to the east of Ya’ai O increases with the decrease of the top burial depth on the mantle; 2) the heat flow does not depend on the age of the island arc; 3) The conclusion that the value mainly depends on the age of geological structure can not be established, but it can be concluded that it is directly related to the recent tectonic activity. 4) Magma source (local melting zone) is the source of maximum heat flux. 30 km.
