Famennian - Dapingian
358.9 - 470 Ma

ID: 2992505
Guilford Quartz Monznoite

Age: Paleozoic (358.9 - 470 Ma)

Stratigraphic Name: Guilford Quartz Monznoite

Description: Biotite-muscovite-quartz monzonite; occurs as discontinuous lenticular bodies; age 420 +/- 50 m.y. * by radiogenic dating.

Comments: Radiogenic date from Wetherill et al., 1966. (ref. MD003). Also second age date reference from USGS Geologic Names lexicon (ref. MD004): Isotopic dating (Rb-Sr) of the Guilford Quartz Monzonite indicates the unit is of Silurian age (425 Ma). Original map source: In 1995 the Water Resources Division of the U.S. Geological Survey digitized the geologic map of Maryland from the 1968 paper map (Reference MD001). Information about products from the Maryland Geological Survey can be found at http://www.mgs.md.gov/.
