Fine microscopic and ultramicroscopic study of a few metamorphic rocks from dam sites
Abstract The study of metamorphic rocks is on the whole a difficult matter. Dam engineering geologists attempt to cast light on the structural data on a microscopic scale. Many methods are used to detect microfissuration, but generally the microscopic field below 100 μ is neglected. It is possible to detect, with a standard microscope which enlarges up to 2,000 times, the anomalies of crystalline structures: primary cavities, secondary fluid inclusions and their alignment which may give information on the engineering properties and on the geological history of the rock mass. Rocks from several dam sites have been examined. In the Malpasset rock, a very dense network of microfissuration was detected, very rich in secondary fluid inclusions, with a great number of alignments.
