Book Description
The Nicola Horst in the southern intermontane belt, British Columbia, is a Tertiary fault-bounded structure that exposes relatively deep-seated metamorphic equivalents of Late Triassic Nicola Group volcanic & sedimentary rocks, intruded by plutons. Associated with the Nicola facies are undated conglomerate & schist units which are unlike any known facies of the Nicola Group but which resemble units of the pre-Nicola, pericratonic succession to the east. This paper presents preliminary results of field work conducted to better understand the evolution & contact relationships of the Nicola Horst and to examine whether the Horst provides evidence regarding the contact between the Nicola Group and the ancient North American cratonic rocks.
