Since 2011, more than 2,000 iSquares have been collected from diverse academic disciplines and from around the world.

This paper presents for the first time chemical data on ancient (Antiquity period) marble quarries of Delos Island and some architectural marbles from its famous exceptionally well-preserved archaeological site. geological substratum is mostly composed granite, including very few decametric enclaves. However, Delian architecture dominated by gneiss marbles. A large quantity had thus to be impor...

Microscope images of marble thin sections can be used to determine their geographical origin by means of the shapes, sizes, and spatial distribution of their grains. In this paper, we present a method that is the first step towards an automatic origin determination, namely, the segmentation of grains in digital images of thin marble sections. Each grain has a preferred direction, different from...
