Is there a relationship between seismic velocity and heat production for crustal rocks
Reads0

TLDR
This article showed that heat production cannot be reliably predicted from seismic velocity, as velocity depends upon the major mineral constituents of rocks whereas heat production results from radiogenic components concentrated in both major and trace minerals in rocks.About:

Nature and composition of the continental crust: A lower crustal perspective
TL;DR: In this article, a three-layer crust consisting of upper, middle, and lower crust is divided into type sections associated with different tectonic provinces, in which P wave velocities increase progressively with depth and there is a large variation in average P wave velocity of the lower crust between different type sections.

Thermal thickness and evolution of Precambrian lithosphere: A global study
TL;DR: In this paper, the authors used the steady state thermal conductivity equation with the same geothermal constraints for all of the Precambrian cratons (except Antarctica) to calculate the temperature distribution in the stable continental lithosphere.
Journal ArticleDOI
The thermal structure and thickness of continental roots
TL;DR: In this paper, heat flow data from the Precambrian shields in North America and in South Africa were compared and the average heat flow values of different Archean provinces in Canada, South Africa, Australia and India differ by significant amounts.
Journal ArticleDOI
Radiogenic heat production variability of some common lithological groups and its significance to lithospheric thermal modeling
TL;DR: In this paper, the radiogenic heat production (RHP) variability of some common lithological groups from a compilation of a total of 2188 representative U, Th and K concentrations of different worldwide rock types derived from 102 published studies is addressed.

Xenolith-controlled geotherm for the central Fennoscandian Shield: implications for lithosphere–asthenosphere relations
Ilmo Kukkonen,P. Peltonen +1 more
TL;DR: In this paper, a 2D model of the kimberlite-hosted mantle xenoliths was used to provide a calibrated geotherm for the central Fennoscandian Shield in eastern Finland, where seismic estimates of lithosphere thickness range from 160 km to more than 200 km.

The velocity of compressional waves in rocks to 10 kilobars: 1.
TL;DR: The velocity of compressional waves has been determined by measurement of travel time of pulses in specimens of rock at pressures to 10 kilobars and room temperature as mentioned in this paper, mainly igneous and metamorphic rocks, furnished three specimens oriented at right angles to one another.
Journal ArticleDOI
Crustal temperature and heat production: Implications of the linear heat‐flow relation
TL;DR: The linear relation between surface heat flow and heat production in plutons is easily explained in terms of an exponential decrease of heat production with depth in the crust as discussed by the authors, which is the only possible explanation, provided that three other assumptions that seem geologically reasonable are made.
Journal ArticleDOI
Heat generation of plutonic rocks and continental heat flow provinces
TL;DR: Combined radioactivity and heat flow measurements in pluionie rocks at 38 localities in the United States define three heat flow provinces; the eastern United States, the Sierra Nevada, and a zone of high heat flow in the western United States which includes the Basin and Range province as discussed by the authors.
Physical properties of marine sediments
John E. Nafe,Charles L. Drake +1 more
TL;DR: In this paper, it was shown that seafloor sediments that blanket the ocean floor are of widely varying thickness but seismic observations indicate that 200 to 400 meters in the Pacific and one kilometer in the Atlantic are fairly typical values for deep water.

Exposed cross-sections through the continental crust: implications for crustal structure, petrology, and evolution
TL;DR: In this paper, the authors concluded that the most prominent layering in the crust is not compositional but metamorphic, and that the continental crust is characterized by lateral and vertical heterogeneities of varying scale which are the apparent cause of the complex seismic reflections recorded by COCORP.
