Hi. My name is Andy. I'm a geologist from Canada who has been collecting minerals for decades and now I have added meteorite collecting to my hobby. This blog is loaded with photos of my personal collection of minerals and meteorites. I have also been adding my own photos of what I think is cool and interesting geology. Unless I indicate otherwise, all the microscope photos amd macro photos have been taken by myself. Please use the "Ask me anything" option to leave comments or questions. I'd love to hear from you.

Tool marks on the base of a Triassic sandstone bed in Banff National Park, Alberta, Canada. Tool marks are a type of sole marking formed by grooves left in a bed by things like sticks or pebbles being dragged along by a current. The average direction of these can be assumed to be the flow direction, though it is bimodal, so it could be either way along the mark. Flow direction in the photo example would be across the page with the longitudinal axis of the tool marks. Several marks appear to become deeper (stick out more) on the right side, suggestion the paleoflow direction was from left to right.

Silty sandy turbidite beds within marine shale of the Jurassic Fernie Formation near Banff, Alberta, Canada. Due to differential weathering, the more resistant turbidite siltstone tend to stick out from the outcrop. The beds are part of an overturned syncline. Depositional scouring marks can be seen on the base of the turbidite units. Top (younger rocks) is towards the right.

Petrified tree stump in the Jurassic-Cretaceous Passage beds of the Morrissey Formation in the Kootenay Group in Banff National Park, Alberta, Canada. The tree stump is seen in cross sectional view and the tree rings are evident in the lower, close-up photo. In the upper photos the petrified tree can be seen sitting at the bottom of a thick sandstone channel. The trunk is marked “T” and outlined in red. The channel is marked “C” and outlined in yellow. The beds are structurally overturned and younger sediments are towards the right, in the direction indicated by the black arrow.

Petrified tree stump in the Jurassic-Cretaceous Passage beds of the Morrissey Formation in the Kootenay Group in Banff National Park, Alberta, Canada. The tree stump is positioned along strike within the structurally overturned shallow marine sediments. Younger beds are to the right. Petrified trunk is just over 1 meter in length.
