Sep 15, 2015 (A Wilson) - This sample was taken from a wide marble belt which trends northeast across the southeastern corner of Dalhousie Township into Lanark and Ramsay Townships. This belt has numerous narrow metasedimentary, amphibolitic, and metaigneous units running parallel to, and contained within it. The belt is several kilometres wide in some areas and up to 20 km in length. It is flanked to the southeast by amphibolite where it is partially overlain by Ordovician sedimentary rocks, and to the northwest by metadiorite and amphibolite. Detailed mapping indicates that the area is underlain predominantly by white calcitic marble. Occurring within the marble are several narrow granitic dikes, most trending in a north-northeast direction. Only minor impurities occur within the marble, with the exception of a couple of narrow tremolite-rich zones.
