#NovaScotia’s northernmost documented mineral occurrence is on St. Paul Island, an extension of the Appalachian Mountains, north of #CapeBreton!
Check out the history of this neat island: the Graveyard of the Gulf!

The mineral occurrence isn’t of any significance – it’s a small outcrop of galena, sphalerite and pyrrhotite in limestone, and marcasite in small quartz veins – but it’s as far north as you can go in #NovaScotia.

What is interesting is St. Paul Island itself. It's in The Cabot Strait, at the entrance of The Gulf of St. Lawrence, about 14 miles from Cape Breton.

It's a wee bit cooler today but nothing like 126,000 years ago when the #AtlanticBubble was covered in ice!
The last ice age ended 10,000 years ago but there have been glacial periods in #NovaScotia on and off for at least 500,000 years...

During periods of climatic cooling, ice sheets develop and advance, aided by the reflection of the sun's light from the white snow surface. Sea levels drop as ocean water is used to make ice. The glaciers grow, coalesce and flow all the way out to...

This was the #AtlanticBubble 400 million years ago!
The 4 provinces were part of 1 landmass as supercontinent Pangea was slowly coming together, a process completed 300 million years ago.
The pictures start with a close-up and zoom out to show our place globally.

North America was part of the Euramerican continent back then. Note that #NovaScotia, on the east coast of Euramerica, was south of the equator. NS had a hot, tropical climate back then and our coal, salt and gypsum deposits formed down south.

The Appalachian Mountains, which formed 480 million years ago when N. America and N. Africa collided, ran 2400kms from Newfoundland to Alabama, right thru the Maritimes. They were taller than the Himalayas but are mostly eroded now. The #CBHighlands are a remnant of them.
