Sign board at Irving Nature Park in New Brunswick, Canada

The photographs in this post show the rocky outcrops and beach stones on one of the seashores around Irving Nature Park near Saint John in New Brunswick, Canada. The characteristics of the beaches in the park are dependent on their location. On this particular beach, the beach stones were fairly uniform in composition and retained angularity but with some of the edges rounded. The exposed rocks on the two arms of the gently curving beach, and also emerging midway from amongst the beach stones, were similar to those I had encountered not far away at Saints Rest Beach.  They are very old, belonging to the Taylor Island Formation PreCambrian volcanic rocks (ZCTIvs) dating from upto 600 million years ago. The colours, textures, and markings were very interesting, and some at least showed evidence of being damaged by a relatively recent tidewater glacier about 15,000 years ago. I also think that the rock outcrop found amongst the beach stones some way along the shore may indicate fracturing on a fault line.

For more information look at the Stonehammer GeoPark website.

I will update this post as I discover more information about the Pre-Cambrian and Cambrian rocks exposed on the shores of Irving Nature Park.
