Metadata Summary

Originator Minnesota Department of Natural Resources, Division of Lands and Minerals, Mineral Potential Evaluation Section
Abstract This dataset consists of information about the geology, geological characteristics, and aggregate potential of crushed stone potential units. Four attribute fields relate to the crushed stone characteristics, including overburden thickness, quality, probability, and bedrock geological unit. These characteristics were used to calculate the aggregate potential of the map unit for crushed stone.

Ordering Instructions The Aggregate Resource Mapping Program's spatial datasets for Carlton County and the Fond du Lac Reservation are included in the file carlton_aggregate_data.zip, accessible from the MN DNR Aggregate Mapping web page: http://www.dnr.state.mn.us/lands_minerals/aggregate_maps/completed/index.html
The spatial datasets are also available as shapefiles and a file geodatabase stored at drive:\data\resource on the associated CD (where 'drive' is the CD reader or writer drive on the PC). The spatial datasets include: sand and gravel potential, crushed stone potential, field observations, mining pits, depleted mining lands, Minnesota Geological Survey (MGS) County Well Index (CWI) data points, sieve analysis table of selected field observations, MGS CWI stratigraphy table, and Mn/DOT ASIS pit quality table.

Selected aggregate resource datasets from this project can also be viewed in the Aggregate Resource Mapping Program's Aggregate Mapper at:

Aggregate Mapper allows users the ability to work with the aggregate resource data without having to download additional software. The site can display spatial and tabular aggregate resource data such as sand and gravel potential, crushed stone potential, field observations, mining pits, and depleted mining lands. This information can be overlaid on a variety of base map information from Web Mapping Services (WMS) sources like; 1:24,000-scale DRGs (digital topographic maps), 1991 black-and-white air photos, and 2008 Farm Service Agency color air photos.

Title Carlton County and Fond du Lac Reservation Aggregate Resource Evaluation - Aggregate Potential - Crushed Stone Potential - carlcsp
Abstract This dataset consists of information about the geology, geological characteristics, and aggregate potential of crushed stone potential units. Four attribute fields relate to the crushed stone characteristics, including overburden thickness, quality, probability, and bedrock geological unit. These characteristics were used to calculate the aggregate potential of the map unit for crushed stone.
Purpose To summarize the geological characteristics, bedrock geology, and crushed stone potential of the different bedrock units in Carlton County and the Fond du Lac Reservation. To help categorize the geological characteristics and incorporate them into a model to help determine the crushed stone potential of the deposit.

Horizontal Positional Accuracy 1:100000

Lineage Two factors control the distribution of crushed stone potential in Carlton County and the Fond du Lac Reservation: bedrock quality and thickness of overburden. Bedrock mapping was completed by MGS (Boerboom, 2009, Bedrock Geology, pl. 2 County Atlas of Carlton County 1:100,000 scale). Crushed stone potential is based on units defined by Boerboom (see Bedrock Geology Plate for detailed unit descriptions). Only two bedrock mapping units, a basalt (MGS map unit Pmc) and a metavolcanic group containing two identified units defined as porphyritic metabasalt (MGS map unit Pvg) and metagabbro (MGS map unit Pga) appear to have physical characteristics suitable for crushed stone. The second factor, overburden thickness, was based on broad observations of bedrock elevation and thickness of glacial overburden (Setterholm, 2009). Exposures of bedrock are observed as isolated knobs. In areas where well data are available, overburden was interpreted to grade increasingly away from the outcrop to approximately 25+ feet thick. Therefore, crushed stone potential is conservatively delineated and spatially limited to areas near outcrops.
