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. |

Mille Lacs County Aggregate
Resource Evaluation - Aggregate Potential - Crushed Stone Potential -

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. |

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. |
