Metadata created using Minnesota Geographic Metadata Guidelines

### Metadata Summary

Originator | MN Department of Natural Resources, Division of Lands and Minerals, Mineral Potential Section, Aggregate Resource Mapping Program
Abstract | This dataset consists of information about the geology, geological characteristics, and aggregate potential of crushed stone potential units. Four attribute fields relate to 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 datasets for Mille Lacs County are included in the file milldata.zip, accessible from the MN DNR Aggregate Mapping web page: http://www.dnr.state.mn.us/lands_minerals/aggregatemaps.html The dataset is also available as aggregate resource data layers stored at drive:\data\resource on the CD (where 'drive' is the CD reader or writer drive on the PC). The datasets include data on sand and gravel potential, crushed stone potential, overburden model source points, field observations, aggregate pits and quarries, County Well Index (CWI) data sources, field observation's sieve database, and MN DOT ASIS pit quality database. In addition, selected Mille Lacs aggregate resource datasets can be viewed in the Aggregate Resource Mapping Program's Aggregate Mapper at: http://www.dnr.state.mn.us/lands_minerals/aggregate_maps/online_maps/index.html Aggregate Mapper allows users with little to no GIS experience the ability to work with GIS data. The site can display spatial and tabular aggregate resource data such as sand and gravel potential, crushed stone potential, field observations, and gravel pits. This information can be overlaid on a variety of reference information from Web Mapping Services (WMS) sources like 1:24,000-scale DRGs (digital topographic maps), 1991 black-and-white air photos, and 2003-04 Farm Service Agency color air photos.

Title | Mille Lacs County Aggregate Resource Evaluation - Aggregate Potential - Crushed Stone Potential - millcspp
Abstract | This dataset consists of information about the geology, geological characteristics, and aggregate potential of crushed stone potential units. Four attribute fields relate to 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. To help categorize the geological characteristics and incorporate them into a model to help determine the crushed stone potential of the deposit.

Attribute Accuracy |
Logical Consistency |
Completeness | The crushed stone potential units were delineated using an overburden model developed and interpreted from the county well index, soil surveys, MGS outcrops, exploratory drilling, and field observations. Additionally, the crushed stone potential was further interpreted using the following Minnesota Geological Survey Bedrock Geology Maps: 'Bedrock Geology of Mille Lacs 30X60 Minute Quadrangle' (1:100,000, M-100, 1999) & Bedrock Geology and Superimposed Magnetic on Gravity Anomaly of East-Central Minnesota' (1:200,000, M-132, 2003).
Horizontal Positional Accuracy | 1:200,000 in the southern portion, 1:100,000 in the northern portion.
Vertical Positional Accuracy | Not applicable.
Lineage | The first step in determining the distribution of aggregate resources is to understand the recent geological history of the area. The geological history basically tells us the story, or sequence of events, of when the aggregate and other sediments were deposited. By understanding this story we can determine where the aggregate was deposited, as well as some of the general characteristics about the material. Data about the overburden, bedrock, and depth to bedrock includes well locations with well log information indicating a depth to bedrock; bedrock outcrops from the soil information; bedrock outcrops from MGS; depth to bedrock information from exploratory drilling; bedrock outcrops observed in the field. To interpret the overburden depth, a GIS based computer model was created using the Spatial Analyst extension in ArcGIS 9.2.
