Writing with Chalk

Updated: Oct 17, 2023

So, your writing is literally life. You write with the calcite skeletons of microscopic marine organisms, of planktonic algae. That is chalk. (Voices of Nature)

I'm the kind of writer who relies heavily on research while writing my stories. When I was working on my rock stories, I read a lot about metamorphism, geology, weathering, rock types, compositions, and more. Little did I know that calcite is the primary material found in both marble and chalk. It seems so counterintuitive, considering that marble is incredibly hard and chalk is soft and easily crumbles in comparison. These are the kind of marvels that you'll encounter in my writing - perhaps the ones that are so straightforward and seemingly simple that we often overlook them.


For instance, the revelation that chalk is primarily composed of calcite skeletons left a lasting impression on me. It instantly transported me back to my childhood days of drawing on the pavement, playing hopscotch, or scribbling on the school board. Yes, back then, we didn't have markers, but we never paused to consider that every line and mark we made left traces of planktonic algae behind. To me, this is one of the most wonderful metaphors for how writing has the power to breathe life into the seemingly mundane.


Now, shifting our focus back to geology, let me conclude this post with a recent research highlight published just yesterday in Geophysical Research Letters. This research pertains to mud volcanoes, both on land and beneath the sea. These geological formations come into existence when mud and rocks suddenly erupt. If most studies have focused on eruptions of fluids from a deep reservoir, new research suggests the importance of surface cracks.


Massimo Nespoli and his colleagues conducted a thorough study of the mud volcanoes located within the Regional Natural Reserve of Nirano Salse in Northern Italy. They employed specialized gravity measurements, revealing that the unique shape of these volcanoes is a result of a substantial crack in the Earth’s surface, known as a fault termination. This challenges the conventional focus on caldera collapse, which resembles a massive hole in the ground, as the sole explanation for these phenomena.


Why does this matter? Well, metaphorically at least, it means that we don't need to dig deep down to uncover hidden truths; they might be right on the surface, waiting to be discovered if we only know how to look.
