Sand Grains, Pantanal, Brazil

I was looking for something simple for my outreach project in western Brazil last October, so I decided to work with sand grains. In the images, we have some commercially mined sand from Aquidauana, state of Mato Grosso do Sul, Brazil. It was wonderful to see the kids (4-6 grade from nearby public schools in the city of Corumbá) marvel at the different shapes, sizes, and angularity of these beautiful quartz grains. The Pantanal and the Paraguay River that courses through it is full of quartz sand and silt.

    Dear @ELO418,

    Welcome to Foldscope community. This is the first post from Brazil; so I am delighted to see you sharing your explorations. We would love to see more posts coming from latin america; specially with the intense biodiversity to share.

    Could you also post some pictures of where you collected the sand from? How is it mined? What happens after the mining?

    The sand was being sold in Corumbá, about 300 km away from Aquidauana, but I know nothing more about where the sand came from. The city of Aquidauana, MS is located on the eastern border of the Pantanal floodplain, so I suspect that the sand comes from floodplain or channel levee deposits. The sand might have been washed to improve its commercial value.
