Composition and Constitution of Ten Samples of Glacial Till, St. Lawrence Seaway Project

摘要

Ten samples of glacial till from the St. Lawrence Seaway Project were subjected to petrographic examination, X-ray diffraction study, and chemical analysis to develop data on their composition and constitution. In addition, some soil tests were made on one sample. This work was done in response to claims by the contractors that, among other things, the till contained excessive fines and was cemented by a calcareous material. (Author)
