... Complutense, Madrid, Spain ABSTRACT: The Moon has a surface constituted mainly of basaltic materials. They are mostly vacu -olar-like basalts that are also abundant in soils of volcanic origin on Earth. The geotechnical features of these rocks from the Canary Islands are supported by the basic characteristics...
