Description
Piece of course-grained intrusive Dolerite from a Tertiary age dyke structure at Grinshill quarry in Shropshire. This specimen has been cut and sectioned to produce microscope thin sections.
Diabase (dolerite) is a dark-colored igneous rock. It is compositionally equivalent to gabbro and basalt but texturally between them. Diabase is a common rock type. It occurs mostly in shallow intrusions (dikes and sills) of basaltic composition.
Imaged using a canon 5DS R and Stackshot 3x with turntable to provide 70 images which were then processed using agisoft photoscan at high levels.
