Abstract |
This dataset consists
of information about the textural quality of Minnesota Department of
Transportation Gravel Pits and aggregate sources. Six sieves were used to determine the textural characteristics
of the deposit. Includes the
weighted averages of all textural data within a pit or drilling area. This information was summarized off the
MN/DOT pit sheets. |

Purpose |
This table summarizes
the textural characteristics for the MN/DOT pit sheets. Six sieves were used to determine the
textural characteristics of the deposit.
Includes the weighted averages of all textural data within a pit or
drilling area. This information was
summarized from the MN/DOT pit sheets.
This table is a very gross indication of the textural characteristics
and should only be used as a large scale guide. |

Attribute Accuracy |
The ranges of values
were taken directly from MN/DOT pit sheets.
These numbers were also averaged to represent the entire pit. However, a pit may vary in textural
composition very much from one end to the other, or the top 10 feet may be
very different from the lower 10 feet.
Thus, great care must be taken when interpreting this information. For further detail, please see the pit
sheets from MN/DOT. |

Overview |
The ranges of values
were taken directly from MN/DOT pit sheets.
These numbers were also averaged to represent the entire pit. However, a pit may vary in textural
composition very much from one end to the other, or the top 10 feet may be
very different from the lower 10 feet.
Thus, great care must be taken when interpreting this
information. For further detail
please see the pit sheets from MN/DOT.
These data can be related to their locations, stored in the gvl_pits
shapefile, by relating on the sourcexx field in dot_qual.dbf and the
asis_number field in gvl_pits. |
