THE PRESIDENT (Professor P. Allen) asked Dr Grocott if the structural history in his field area reflected events in the broader context (e.g. jostling of the Greenland blocks). DR M. K. WELLS asked the author to comment on possible variations of fabr

The elastic properties of the longer bones of the fore and hind limbs of an osteopetrotic Angus calf were measured using an ultrasonic technique. The same bones of a second Angus calf with unaffected bone tissue were also studied. The osteopetrotic b

A pulsed ultrasound Doppler velocity meter has been used to map the time varying velocity waveforms in the exposed left coronary arteries of anesthetized ponies. Velocity measurements were made without invading the vessels or disturbing the hemodynam

The Freetown Intrusion, Sierra Leone, evolved by recurrent injection of olivine-bearing magma producing an aggregate thickness greater than 6000 m of rhythmically layered rocks. Sedimentation and constrained viscous flow of crystallizing magma concen

SUMMARY. The stratigraphical limits on the age of the Freetown intrusion, Sierra Leone, are very wide, yet the intrusion has not previously been accurately dated by isotopic methods, despite a number of attempts. Rubidium-strontium dating of acid vei

SummaryA gradational increase in concentration of CO2 towards the margins of a very fine-grained basalt dyke has led to the development of a pale marginal facies, enriched in carbonates, particularly siderite. Increases in CO2 from about 3 % in the i

A method is described of finding the directions of the principal axes of stress at any point of a thin slice cut from a "frozen stress" model. The paper includes an account of the method of recording results by a stereographic projection, and a descr

The hypersthene-gabbro of Ardnamurchan Point is the earliest of the intrusions of Centre 2 of the Ardnamurchan complex as shown by 5. E. Richey (11, p. 208).I The mass is intruded into domed Jurassic sediments and Tertiary basalt flows (fig. 1). The

A layer of massive and lineated hornblende-biotite-gneiss has fractured along ac-joints (perpendicular to the layering and b–lineation), at regular intervals along its lower surface in contact with a thin marble bed. The joints have been opened fro
