Magmatic processes were important on the nascent Earth during the first 500 million years (Ma) after accretion, yet the causes and timing of this early magmatism are largely unconstrained, as no rocks from this period have been discovered. Rare >4000

Research was conducted to determine the influence of crop plants in weathering of ground basaltic rock by monitoring crystalline secondary mineral formation. The basalt, from Duluth, Minnesota, is similar in mineralogy, chemical composition, and text

This paper presents new data on sulfide assemblages, platinum group elements (PGE's) and halogen contents of biotites in anorthositic series rocks from the Duluth Complex. The data are contrasted with similar data from troctolitic series rocks. Sulfi

Exploration for unconformity-type uranium deposits in the late 1970s in east-central Minnesota led to the discovery of several uranium-bearing phosphorite occurrences in rocks of early Proterozoic age. In this report the authors use the term phosphor

Optical examination of nine polished grain mounts of Luna-24 drillcore material (0.09-0.50 mm size) revealed melt inclusions in olivine crystals. Two inclusions consist of clear glass with exceptionally high Si, yet contain no visible daughter minera

More than 2000 fragments were studied microscopically, and electron microprobe analyses were made of 39 selected areas, from a few square mm of polished surface, through 75- to 425-μm fragments of lunar soil from two samples of the Luna 16 core. The
