Geoscientist Jelle Zeilinga de Boer shares his expansive knowledge of Connecticut in a series of entertaining essays about the unexpected ways the land shapes the way we live. An utterly unique way to engage with local history, Stories in Stone reveals the secrets embedded in the world around us-in its rocks, deep below its surface, and in its unpredictable and outsized weather.
You might have noticed that pretty as my komatiite deskcrop is, when I wanted to show the most impressive examples of spinifex textures, such as the variations in crystal size within a lava flow, I had to resort to field photos. In fact, whereas those photos come from a lovely fresh exposure in a stream bed, the hand sample on my desk comes from a nearby field, where the outcrop was rather badly weathered and horrible. This was deliberate: the small exposure in the stream is one of the best examples of spinifex textures found in the entire Barberton Greenstone Belt, and much of its value comes from being able to study the relationships within and between the different lava flows (in fact, we were visiting the locality with 60-odd students in tow for precisely this purpose). Hacking off a chunk simply to beautify my desk would therefore be rather irresponsible.
