Thanks for the reply Midas.

Unfortunately I have neither the training nor experience to carry on a logical dialogue with you about mineralogy and metamorphic sequence. My information was based upon an old text covering archean rocks and low-grade vs. high-grade terrains. Looking at maps and magnetic surveys led me to believe NWI is probably located in an area that could be classified as a high-grade terrain. I know my geo friend was surprised when he saw NWI's latest sections showing the former gneiss now as paragneiss. He had assumed it was probably granitic gneiss. This change caused him to wonder if perhaps the nickel bearing rock was indeed part of an intrusive.

However, I have a question for you. In your estimation, would the nickel bearing rock be older than the paragneiss or would the paragneiss be older. Secondly, is it usual to find a body of rock similar to NWIs (which according to their sections varies from mixed gabbro, gabbro and norite to pyroxenite and gabbro) floating over a bed of gneiss as indicated in all sections given to date.

Regards,

Bob
