Aug 17: earthcache - "Ya Got To Know When to Holdem,Know When To Fold em"

This is a new section that was created by the construction of the new Walmart in New Glasgow, Nova Scotia.

The strata are part of the Pennsylvanian Cumberland Group (Stellarton Formation) in the Stellarton Basin, Pictou County, Nova Scotia. Located behind the Highland Mall in New Glasgow, the outcrop is approximately 500 metres south of the Cobequid Fault, which forms the northern margin of the basin. The section comprises interbedded oilshale, mudrock and sandstone, which are interpreted as freshwater open-lacustrine and lacustrine delta deposits.

The Stellarton Basin is interpreted as a transtensional basin, occupying a pull-apart structure developed at a releasing bend on the Cobequid-Hollow fault system. Late-stage shortening which resulted in a positive flower structure along the northwest basin margin, is probably responsible for the folding.

and another on in front of a different section

i needed to calculate the stike & dip of the rock layers.

quite impressive

the layers go in all directions

you can just image the forces required to bend the layers of rocks.

a closer view of one of the folds

interesting water patterns in the rocks.
