Exploring Franklin County examples

Appendix 6

  

This is a section of a page from “Exploring Franklin County” --  Appendix 6.


Note that these layers were formerly horizontal but have been tilted down to the east by quake movements along the Eastern Border Fault. Conglomerate rock (circles) is concentrated to the east of all the sedimentary layers since this area would have been closer to the steep mountains, where river flow was fast.

5.  The Massachusetts Geological Survey  [https://mgs.geo.umass.edu/ ]

A good resource to explore. Get Free Geologic Quadrangle Maps!!! See below

For geologic details about any spot in Franklin County or Massachusetts, you need the Geologic Quadrangle maps of your area of interest. There are two basic types: Surficial (glacial and recent deposits) and Bedrock. It is often difficult or inconvenient to find these maps, but they are online!  See below.

Dr. Steve Mabee is our Massachusetts State Geologist. I asked him for the best way to access Geologic Quadrangle maps and his answer is below. The “GQ” maps are the way geologists and others investigate an area. They are the result of detailed field work and analysis. Note that older maps will have had formations renamed and perhaps reinterpreted, so do one more step for current geological data: go to the site described in “1” page 187. This database will have updated names and geological time dates, however, the GQ maps have greater detail. They also have a written narrative of the geologic formations and history. Geologic cross sections are included. In other words, whether you are a professional or just wish a deeper look at your “spot”, the GQ map series is where you need to go. 

 

Steve Mabee, State Geologist, suggests this two step process.

1. First, find out what quadrangle map you are looking for.   Steve created an index map showing all the watersheds, towns and quadrangle names for MA.  Go here: http://mgs.geo.umass.edu/resources/quad-index 

Or http://mgs.geo.umass.edu/biblio/what-75-quadrangle-am-i-pdf-paper-map

You will see a map of this index or you can load the index into Google Earth as a kmz file and see more detail for locating your area of interest within each quad.

2. Once you know what quad you want, go to the Geologic Map Database found here:  https://ngmdb.usgs.gov/ngmdb/ngmdb_home.html 

Select “Map Catalog”.

Enter the name of the quad under “Title”, select the type of map (surficial or bedrock) under “Geology Themes” and then select “Massachusetts” under State or Territories.  

This will give you the link to the map!  Just click on the map and you can preview it as well as download various options.
