Breaking (Bad) Calcite - Mineral Cleavage

Source/Author: Scott Brande
Subject: physical geology, mineral properties
Description: The mineral calcite exhibits excellent cleavage in three directions. When it is mechanically broken, fragments form in a rhombic geometric shape. This is demonstrated in the video. An ending close up image of fragments is shown.
Duration: 00:00:48
Comments: Appropriate for an introductory earth science lecture and laboratory course that covers mineral properties.
