Study of Rock-Water-Nuclear Waste Interactions in the Pasco Basin, Washington. Part I. Distribution and Composition of Secondary and Primary Mineral Phases in Basalts of the Pasco Basin, Washington

摘要

In Part I of this report the results of Task III are presented and discussed. The subject of Task III is the study and identification of secondary and primary mineral assemblages in basalts of the Pasco Basin of southeastern Washington. In particular, we have determined the relative amounts, crystallization sequence, and compositions of secondary minerals found lining vesicle and fracture surfaces. This information, together with data on the chemical composition of primary minerals and the extent to which they have undergone dissolution, has been used in theoretical simulations of mass transfer which is the subject of Part II (Task IV) of this report.
