§ 31. Mr. John Pageasked the Parliamentary Secretary for Science what part the Geological Survey and Museum is playing in the preparation of the pro posed tectonic map of the world; and what progress has so far been made in the construction of this map.
§ Mr. Denzil FreethThe tectonic map of the United Kingdom has been prepared by the Geological Survey as part of a co-operative scheme for a tectonic map of Europe, which it is hoped will in due course form part of a similar map of the world.
§ Mr. Scott-HopkinsCan my hon. Friend tell the House what the word "tectonic" means?
§ Mr. FreethA tectonic map portrays major deformations and dislocations which have affected the rocks since their formation, changes resulting from earth movements, and what I am informed is called volcanicity.
