Physical properties of marine sediments

TLDR
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.
Abstract
: The unconsolidated 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. At present direct observation of these sediments is limited to such samples as may be recovered by dredging or coring operations, for drilling has been carried out only in the shallow waters of the coastal shelves. Knowledge of the physical properties of the great bulk of the sediments deeper than the few tens of feet reached by coring equipment is thus necessarily derived from geophysical observations.

Crustal structure and rift architecture across the Krishna–Godavari basin in the central Eastern Continental Margin of India based on analysis of gravity and seismic data

TL;DR: In this article, a 3D gravity interpretation of both the onshore and offshore sections of the Krishna-Godavari basin integrated with detailed seismic reflection and refraction data provided significant new information about the crustal architecture and the early breakup history of the basin.

Thin oceanic crust below Bay of Bengal inferred from 3-D gravity interpretation

TL;DR: In this article, the 3-D gravity effect of the sedimentary layer computed for the derived density distribution shows large variations ranging from −5mGal over the Ninetyeast Ridge near the equator to as low as −210mGal at the apex of Bengal Fan in the Bangladesh shelf region.

A heat production model for stable continental crust

R.G. Allis
- 20 Aug 1979 - 
TL;DR: In this paper, a modified heat production model for stable continental crust is proposed based on constraints from density, seismic velocity and the inferred composition, which implies that lateral variations in surface heat production decay exponentially with depth to a mean value of approximately 0.7 μW/m3 at the base of the upper crust.

Experimental estimation of velocities and anisotropy of a series of Swedish crystalline rocks and ores

TL;DR: In this paper, the authors collected and measured more than 50 rock and ore samples for their seismic velocities in two mining camps and a carbonatite complex of Sweden, using 0.5 MHz P- and S-wave transducers.
