Mineralogical Characterization of Baptistina Asteroid Family: Implications for K/T Impactor Source
, 2011 Bottke et al. (2007) linked the catastrophic formation of Baptistina Asteroid Family (BAF) to the K/T impact event. This linkage was based on dynamical and compositional evidence, which suggested the impactor had a composition similar to CM2 carbonaceous

CleanMat, EarlyView.Oyster shell (OS) as a sustainable calcium source for chromium recovery from tannery sludge via co‐pyrolysis. OS outperformed CaCO3, achieving > 95% Cr recovery, attributed to its organic matrix proteins enhancing adsorption and phase conversion. The oxidation of tannery sludge Cr(III) to Cr(VI) improved recyclability, aligning with circular economy ...

Routine characterization and interpretation of complex alkali feldspar intergrowths [PDF]
, 2015 Almost all alkali feldspar crystals contain a rich inventory of exsolution, twin, and domain microtextures that form subsequent to crystal growth and provide a record of the thermal history of the crystal and often of its involvement in replacement ...
