The work of this project was divided between analytical chemistry by xray fluorescence techniques and geologic interpretation of a series of PreCambrian crystalline rocks from the contact aureole of the Stillwater igneous complex in the Beartooth Mts. of Montana. The former was needed for the latter. There are two sections to the report which correspond to the double thrust of the research.
The purpose of this section of the paper is to document the xray fluorescence methods used to obtain the data reported on Rb, Sr, Fe, Mn, and Ti concentration values in a later section of the paper. Also, a new instrumental approach and a new analytical method are suggested for the analyses of the elements of atomic number 21-26 (Sc-Fe). All methods involve estimation of the mass absorption coefficient (μ) of the rock.
