Lithology Comments

Sep 11, 2015 (A Wilson) - The marble found in this area is part of a metasedimentary belt which occurs on both sides of Rideau Lake. Much of the belt is overlain by Paleozoic sandstone and conglomerate. The marble ranges in texture from fine to coarse grained and in colour from medium grey to white. Marble in this area is predominantly white but ranges from pure white with only minor graphite and phlogopite, to impure buff with siliceous clots and bands. Some of the area is overlain by Paleozoic conglomerate which grades laterally into poorly sorted sandstone and conglomerate. Garnet-biotite paragneiss units within the marble tend to be discontinuous, trend northwest, and are normally less than 30 m wide. Of the four areas mapped, only one yielded a poor quality marble. Each of the other areas has development potential assuming that the marble is of adequate quality, although for each, factors other than marble quality must be taken into account.




Mineralization Comments

Sep 11, 2015 (A Wilson) - Samples 1206 and 1211 were taken from a marble unit (samples 1199 to 1213) that has relatively consistent CaO and MgO contents and a high CaO/MgO ratio. The area also has a consistently low SiO2 content. The trace and metallic element contents are also low, with the exception of Sr. In several of the samples Sr is above 1000 ppm, but there seems to be no correlation with any other element except that the marble samples with a high Sr content are calcitic and not dolomitic. Sample 1206 was taken from an area of predominantly clean marble with the exception of several paragneiss units within the marble.
