- 요약Aragonite biomineralization is a process common to many marine organisms and plays a crucial role in the health of many ecosystems, including the currently endangered coral reef. Understanding aragonite biominerals and how they form is crucial to informing responses to climate change that focus on helping marine biomineralizes like coral.Using a combination of microscopy and spectromicroscopy techniques, this work aims to expand our understanding of how aragonite biominerals form, and what physical processes govern that formation. Electron backscatter diffraction was used to reveal a new model of crystal twinning in aragonitic nacre, and points towards a physical process governing twin formation in biominerals. Photoemission electron microscopy (PEEM) was used to show metastable precursor phases to aragonite at the forming edge of multiple aragonite biominerals, including newly revealed crystalline precursors. This finding was corroborated by detection of these same precursors with synchrotron infrared nano spectroscopy. The rate at which these precursors convert into mature aragonite was also measured with PEEM to show a correlation between crystallization rate and resilience to ocean acidification in coral.
