Don't Panic Geocast

In this episode of the Don't Panic Geocast, we dive into the fascinating world of dolomite, a mineral that is commonly found in sedimentary rocks. They discuss the unique characteristics of dolomite and the different ways in which it is formed. We also highlight a fun paper on equine dietary preferences, which explores the food choices of horses in different environments. The paper reveals interesting insights into the feeding habits of horses and how they adapt to different conditions Fun Paper Friday Goodwin, Deborah, Pat Harris, and Nell Davidson. "Behaviour of stabled horses presented with foraging devices in mangers and buckets." (2005): 96.
