This Geographic Information System (GIS) point layer, Abandoned Mines of
New Jersey contains locations
and attributes for abandoned mines. The shapefile has locations for
nine types of abandoned mines which are Copper,
Graphite, Iron, Lead, Mica, Manganese, Sulfide, Uranium and Zinc. There are
588 abandoned mine locations in the
database and they are mapped at a scale of 1:24,000.
This updated version of the data has undergone significant changes in two USGS quadrangles since the previous version of this data, dated July 29, 2005, was published. Previously, Bloomsbury, Blairstown, Easton and High Bridge USGS quadrangles were updated. In this update, field work by geologists was conducted to improve the locational information of the mines in the Franklin and Riegelsville USGS quadrangles. Some of the mines in these quadrangles were located
using the global positioning system
(GPS). Certain mines in these quadrangles were mapped for the first time
and appear in this data but not in the previous
versions of the data. Some known mine locations in the previous versions of
the data have been more accurately mapped
and the points have been relocated.
