...Andrew J. Pearce; J. A. Elson Abstract Average rates of denudation over periods ranging from 11 800 years to 12 800 years at sites on Mont St. Hilaire, Quebec were estimated as follows: The rates of fluvial denudation at Mont St. Hilaire are lower by a factor of one-half than published short term...

...G. R. Webber; J. U. Jellema Abstract Soil samples from Mont St. Hilaire, one of the Monteregian Hills of Quebec, were analyzed by X-ray fluorescence for the elements Fe, Ca, K, Ti, Mn, Sr, Zr, Nb, Zn, and Rb. The samples were taken below the surface organic-rich horizon.The composition...

...R. T. Wilkin; H. L. Barnes Abstract The solubilities of analcime and clinoptilolite were determined in dilute, weakly alkaline, aqueous solutions below 300 degrees C and at vapor-saturated pressures. Analcimes used in this study were from Mont St. Hilaire, Quebec (an 1 , Si/Al = 2.02) and Wikieup...

...Gerald Giester; Yunxiang Ni; Dietmar Jarosch; John M. Hughes; Jorn G. Ronsbo; Yang Zhuming; Josef Zemann Abstract Six cordylites from the four known localities [Narssarssuk (Greenland), Mont St. Hilaire (Canada), Bayan Obo (China), and Kola Peninsula (Russia)] were investigated by electron...

...Robert F. Martin Abstract Gabrielle Donnay (née Hamburger) died peacefully at her home, on the flanks of Mont St. Hilaire, on April 4th, 1987. Gai was born in Landeshut, Silesia (in Germany at the time, now part of Poland). Her father was a textile manufacturer, and her mother had a career in music...

...Subrata Ghose; P. K. Sen Gupta; Charles F. Campana Abstract Montregianite, Na 4 K 2 Y 2 Si l6 O 38 ⋅ 10H 2 O from Mont St. Hilaire, originally reported to be orthorhombic, is actually monoclinic (pseudo-orthorhombic) with unit-cell dimensions a = 9.512(2), b = 23.956(4), c = 9.617(2) Å, β = 93.85(1...

... patterns from which the hexagonal cell dimensions have been determined to be a 10.451(3), c 6.510(2) Å, very close to those of burbankite from Mont St. Hilaire, Quebec. The Wyoming burbankite is heavily contaminated with organic matter which can be removed by moderate heating. The decomposition temperature...

... observations, optical properties, cell dimensions, and 2 new chemical analyses which confirm the formula are reported. Optical properties and cell dimensions of leucosphenite from many sources in the Green River Formation and from Mont St. Hilaire, Quebec, show little variation. Leucosphenite nlelts...

...G. Y. CHAO Abstract Carletonite, a new mineral from Mont St. Hilaire, Quebec, is tetragonal P4/mbm , with a = 13.178 Å, c = 16.695 Å, and z = 4. The structure was solved by threedimensional Patterson synthesis and refined by full-matrix least-squares method using anisotropic temperature parameters...

...J. A. Mandarino; D. C. Harris Two types of epididymites have been found at Mont St. Hilaire. The first consists of euhedral crystals which are tapering pseudo-hexagonal prisms, most only a few millimeters long; all have a soft grayish-brown covering. The second type consists of radiating groups...
