Summary

Description

Finely-laminated dolostone in the Devonian of Ohio, USA.

This is part of a large, loose block at an active quarry in far-northwestern Ohio. We were forbidden from closely approaching the walls. Rock piles on the quarry floor were available for close examination and mineral collecting.

This specimen is from the Lucas Dolomite of the Detroit River Group. The Lucas appears to consist of both dolostone and limestone. Finely-laminated, brown dolostone is a common lithology in this unit. Lack of stratigraphic control in the loose quarry blocks makes additional, specific lithologic assessments difficult. Stylolites are also present in the Lucas.

The finely laminated portions of the Lucas have been identified by other workers as microbial mats.

Stratigraphy: Lucas Dolomite, upper Detroit River Group, Middle Devonian
