Collection of Geochemical Samples from Minnesota Minnesota Geological Survey, in cooperation with industry, sampled the State of Minnesota and adjacent regions for till geochemistry and indicator minerals at a 30-km spacing during summer 2004. Within target cells, each a quarter-degree latitude by a half-degree longitude, till from between about 1 and 2 m depth was sampled by filling a 15 liter plastic pail. At a few sites, vertical profiles were collected. In addition, three transects to the north were sampled, to help identify sediments derived by long-distance glacial transport, to obtain reference samples from the Thompson nickel belt, and also to extend sampling to the limit of Hudson Bay-derived carbonate-bearing sediments, to permit comparison to Minnesota...

This collection of over 6,400 sets of drill cuttings dates as far back as the late 1800s. The collection is stored in our soil lab at our office and is accessible to the public by appointment. Each borehole cutting set is assigned a MGS lab number upon arrival, processed and washed by UMN student soil lab workers, and stored chronologically in cardboard boxes. Each cutting set cardboard box contains multiple paper envelopes representing a sample taken at that depth. Each paper envelope contains ~100-200 grams of original sample and ~100 grams of washed sample processed by...
