On one side this may look like just a ordinary clam shell but when you flip it over it contains beautiful golden calcite crystals. The crystals formed when the clam died and a cavity formed allowing the crystals to develop. Took over two million years to do this. Found on the east coast of Florida in Brevard County.

Cracker Lake, Glacier National Park

Suspended glacial silt gives the lake it’s otherworldly turquoise color. I saw so many photos of this lake before hiking there (about 6 miles each way) and still could not believe how beautiful it was - I never wanted to leave!

The Geology of the Channel Coasts

I found this geologic map while randomly searching files the other day and I was impressed at how much of the geologic history of this area, home to two of Europe’s major cities, is displayed right here.

The rocks to the far northwest are heavily faulted, folded, and metamorphosed. These rocks are the last remnant of Pangaea; the continent that is today Europe collided with the continent that is today North America, thrusting up a number of great mountain ranges, including the Variscan mountains represented by these rocks.

Spotted Lake | #Geology #GeologyPage #BritishColumbia

Spotted Lake is a saline endorheic alkali lake located northwest of Osoyoos in the eastern Similkameen Valley of British Columbia, Canada, accessed via Highway 3. Spotted Lake is richly concentrated with various minerals. It contains dense deposits of magnesium sulfate, calcium and sodium sulphates. It also contains high concentrations of eight other minerals and lower amounts of silver and titanium.

Bear rock We regularly share interesting shaped rock formations formed by erosion. This granite work of nature’s art is located in Sardinia. The type of structure is called Tafoni, or honeycomb structure, and results from water leaching dissolved minerals to the rock surface. As it dries the minerals precipitate and flake off layers of rock in a process called cavernous weathering. The shape of the formation therefore reflects the movement of fluids through the granite.

I’m an igneous and metamorphic petrology kind of gal, but I when I looked down the microscope at this limestone I audibly gasped. These nebula-looking things are protists called foraminifera that have been replaced by calcite. The forams are identified by their chambered tests, which are preserved in the rock, showing the protist’s original shape.
