rocks‚ only those of volcanic origin are implicated in high aqueous arsenic concentrations. Sedimentary rocks tend not to bear high arsenic loads‚ and common matrices such as sands and sandstones contain lower concentrations owing to the dominance of quartz and feldspars. Groundwater contamination by arsenic arises from sources of arsenopyrite‚ base metal sulfides‚ realgar and orpiment‚ arsenic-rich pyrite‚ and iron oxyhydroxide. Mechanisms by

At the end of World War ² Japan began to capture areas in Asia and the Pacific that had valuable materials such as coconut copra‚ rubber and quartz. The inhabitants of captured territories where more or less given the status of slaves.

In many places rock units can be described‚ grouped together‚ given similar characteristics‚ and placed into lithofacies. These lithofacies are important for interpreting the past depositional settings of the rock units. At the Cemex Quarry‚ we went through three stratigraphic columns‚ describing the different rock layers‚ and placed them into distinct lithofacies. The first lithofacies we described was of an Imbricated Clast-Supported Conglomerate. The first thing that stood out was the orientation

This is relatively soft‚ so opal is sometimes coated with a thin layer of clear quartz. This is to make the opal more resistant to scratches. These are called opal doublets or triplets. An imperfection of the opal is crazing. That is when the gemstone is damp and then dried too quickly or suddenly exposed to intense light‚ which forms
