Lacustrine carbonate deposits with spherulitic facies are poorly understood, but are key to understanding the economically important “Pre-Salt” Mesozoic strata of the South Atlantic. A major barrier to research into these unique and spectacular facie... Read More about Are spherulitic lacustrine carbonates an expression of large-scale mineral carbonation?

The hydrochloride salt of isonicotinamide, C6H7N2O+·Cl-, has been synthesized from a dilute solution of hydrochloric acid in acetonitrile. The compound displays monoclinic symmetry (space group C2/c) at 150 K, similar to the related hydrochloride... Read More about Crystal structure of 4-carbamoylpyridinium chloride.

The origin of spherical-radial calcite bodies - spherulites - in sublacustrine, hyperalkaline and saline systems is unclear, and therefore their palaeoenvironmental significance as allochems is disputed. Here, we experimentally investigate two hypoth...
