The Lost Horse intrusives are minor plutonic bodies occurring to the north and northeast of Copper Mountain, B.C. The rocks of the intrusives were classified by megascopic examination. It was felt that microscopic examinations of the rocks might bring out relationships which were obscure megascopically. Such was the case. The nine specimens examined, which were divided megascopically into six types, were found to consist of only three distinct rock types.
The identity of the three rock types had been obscured by weathering and by different types of hydrothermal alteration. Now that the changes brought about by weathering and hydrothermal alteration are recognized, fewer rock types will appear .on the detailed maps and, in addition, zones of alteration may be outlined. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate
