The Depositional Record, EarlyView.Microbialites are common throughout the rock record and key to our understanding of Earth history, yet a relatively common microscopy technique—cathodoluminescence (CL)—has not previously been leveraged to understand them. In this contribution, we examine microbialites of varying ages (modern to Proterozoic) with CL and report on the patterns and ...

A review of the methods used to study biocompatibility of Portland cement-derived materials used in dentistry [PDF]
, 2006 Advanced restorative dentistry may necessitate the need for surgical intervention to the infected root apex. Once access to the root end is achieved, the root apex is resected and filled with a dental restorative material.

The Depositional Record, EarlyView.Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.
