The Norbeck Intrusive Suite is an Ordovician granitic pluton in Montgomery County, Maryland. The intrusive suite was originally mapped as the Norbeck Quartz Diorite by Hopson,[1] and is shown as such on the Geologic Map of Maryland of 1968. A. A. Drake later revised the name after more detailed mapping.[2] It intrudes through the Wissahickon Formation.

Description

Three lithologies were mapped in the Kensington quadrangle by Drake:[2]
