Graham Baird: How do crystals work? Natural Resources Revenue Data. Tourists who stole sand from beach in Sardinia could face up to six years in prison. A pair of tourists face up to six years in prison after allegedly stealing a large quantity of sand from the pristine beaches of Sardinia.
The French couple were found to have nearly 40kg (90lb) of fine white sand in the boot of their car. The vehicle was stopped during a routine check by border police as the tourists were preparing to board a ferry in Porto Torres, on the north coast of the island, bound for Toulon in France. The sand was found in 14 large plastic bottles and had been taken from a beach near Chia in southern Sardinia. Sardinia re-homes sand taken from its beaches by pilfering tourists.

The 'Images of Clay' Archive is an ongoing project of the Society's Clay Minerals Group and The Clay Minerals Society (USA).
The idea behind this project is to build a collection of high quality images that are freely available to all to download for non-profit purposes, such as the teaching of clay mineralogy (see the copyright statement below). Suitable images include electron micrographs of clay minerals, or indeed any image associated with the study of clay mineralogy.
Anyone wishing to contribute images to the archive should e-mail them to to Steve Hillier, at email@example.com. The Mineralogical Society of Great Britain and Ireland - Kaolinite. M.

Scientists explain ancient Rome's long-lasting concrete. Image copyright JP OLESON Researchers have unlocked the chemistry of Roman concrete which has resisted the elements for thousands of years.
Ancient sea walls built by the Romans used a concrete made from lime and volcanic ash to bind with rocks. Now scientists have discovered that elements within the volcanic material reacted with sea water to strengthen the construction. They believe the discovery could lead to more environmentally friendly building materials.
Unlike the modern concrete mixture which erodes over time, the Roman substance has long puzzled researchers. USGS Asbestos CA Map.

Gypsum — a key ingredient in the manufacture of drywall and plasters — forms through a four-stage process, beginning with the formation of bits of nanocrystalline calcium sulfate that gradually assemble into larger aggregates, according to new research.
Credit: James St. John, CC BY 2.0 Drywall and plasters made from both natural and manufactured gypsum are commonly used in home and building construction around the world, in part because of gypsum’s widespread availability. Despite its abundance, and its seemingly simple makeup, however, relatively little is known about how the calcium sulfate mineral forms in nature. In a recent study, researchers have shed new light on the multi-stage process by which gypsum grows — and the findings could help develop more efficient ways to manufacture the material.
The new research, published in Nature Communications, builds on a body of earlier work trying to sort out how gypsum forms. Fs2008 3089. Thomas Thwaites: How I built a toaster. Your House. Rocksare1.
