Soil Pb concentrations from three 30.5-m× 30.5-m squares at an abandoned smelter site in Socorro, New Mexico, are reproducible only within several hundred ppm. There was no statistically significant difference in log-transformed sample means for two

Illite/smectite (I/S) and illite samples that appear to be 1Md polytypes on the basis of the lack of diagnostic reflections can be resolved as partly either 1M or 2M~ or both by either vapor solvation in ethylene glycol for 40 to 80 hr at ambient tem

The difference in intensities of the 10 A X-ray diffraction maxima of sedimented clay minerals after treatment with ethylene glycol and after heating is generally assumed to be due to the collapse of expandable clay minerals to 10 A. Therefore, this

An exposure of Precambrian Sioux Quartzite near the city of New Ulm, Minnesota, shows evidence of intensive chemical weathering. The silica cement matrix material of the quartzite has been removed and the argillaceous part (probably sericite) of the

Variations in the relative abundance of kaolinite and illite in the clay-size fraction of the Ordovician Glenwood Formation of southeastern Minnesota, western Wisconsin, and northeastern Iowa suggest that the source area for this shaly unit was to th

A 2.5 ft-thick oolitic dolomite in the Shakopee Formation (Lower Ordovician) exposed near Lanesboro, Minnesota, contains scattered detrital quartz grains with multiple overgrowths. More than 75% of the quartz grains in the bed have multiple overgrowt
